An irregular heartbeat can feel like fluttering, pounding, racing, skipped beats or an unexpected pause in the chest. Sometimes these sensations are harmless, but they may also be caused by an abnormal electrical rhythm that requires evaluation by a heart-rhythm specialist.
If you are searching for the best electrophysiologist in Hyderabad, it is important to understand what an electrophysiologist does, which conditions they treat and what expertise to consider when choosing a specialist.
Dr. M.S. Chandramouli is a Consultant Electrophysiologist and Heart Failure Specialist at Yashoda Hospitals, Secunderabad. He specialises in diagnosing and treating abnormal heart rhythms using advanced techniques such as electrophysiology studies, 3D cardiac mapping, radiofrequency ablation, pacemaker implantation, ICD implantation and cardiac resynchronisation therapy.
What Is a Cardiac Electrophysiologist?
A cardiac electrophysiologist is a cardiologist with specialised training in diagnosing and treating problems involving the heart’s electrical system.
The heart has its own natural electrical network. This network produces and carries signals that coordinate every heartbeat. When an electrical signal starts in the wrong location, travels through an abnormal pathway or becomes blocked, the heart may beat:
- Too quickly
- Too slowly
- Irregularly
- Inefficiently
These electrical abnormalities are known as cardiac arrhythmias.
A general cardiologist manages a broad range of cardiovascular conditions, including coronary artery disease, blood pressure problems, cholesterol disorders and heart failure. An electrophysiologist focuses specifically on heart-rhythm disorders and cardiac electrical problems.
An electrophysiologist may use medicines, electrical cardioversion, catheter ablation, pacemakers, implantable defibrillators and other advanced treatments to restore or regulate the heartbeat.
When Should You Consult an Electrophysiologist?
You may be referred to an electrophysiologist when symptoms or test results indicate a possible heart-rhythm problem.
Consider consulting a heart rhythm specialist in Hyderabad if you experience:
- Repeated or prolonged palpitations
- A suddenly racing heartbeat
- Irregular or skipped heartbeats
- Unexplained dizziness
- Fainting or near-fainting episodes
- An unusually slow pulse
- Persistent fatigue associated with a slow heartbeat
- Breathlessness during episodes of rapid heartbeat
- Recurrent chest discomfort with palpitations
- A previously diagnosed arrhythmia
- A family history of sudden cardiac death
- Problems involving an existing pacemaker or ICD
Patients diagnosed with atrial fibrillation, atrial flutter, SVT, heart block, ventricular tachycardia or other rhythm abnormalities may benefit from a dedicated electrophysiology consultation.
Palpitations accompanied by chest pain, severe breathlessness, fainting, confusion or collapse require urgent medical attention.

Heart-Rhythm Conditions Treated
1. Atrial Fibrillation
Atrial fibrillation, commonly called AF or AFib, is an irregular rhythm that begins in the heart’s upper chambers.
Patients may experience:
- Irregular palpitations
- Breathlessness
- Tiredness
- Reduced exercise capacity
- Dizziness
- Chest discomfort
Some patients do not notice any symptoms and are diagnosed during a routine ECG or health examination.
Treatment may include medicines to control the heart rate or rhythm, anticoagulants to reduce stroke risk, electrical cardioversion or catheter ablation. Treatment must be personalised according to the patient’s age, symptoms, stroke risk and underlying medical conditions.
2. Supraventricular Tachycardia
Supraventricular tachycardia, or SVT, is an abnormally fast rhythm that usually begins above the heart’s ventricles.
An episode may start and stop suddenly. The heartbeat can become very rapid, even when the patient is resting.
Symptoms can include:
- Rapid pounding heartbeat
- Chest discomfort
- Dizziness
- Breathlessness
- Anxiety
- Weakness
- Fainting in more significant cases
An electrophysiology study can identify the abnormal electrical circuit responsible for SVT. Catheter ablation may then be used to target that circuit.
3. AVNRT
Atrioventricular nodal re-entrant tachycardia is a common type of SVT. It occurs when an electrical signal repeatedly circulates through pathways near the AV node.
Some patients manage occasional episodes with medicines. When attacks are frequent, prolonged or significantly affect daily life, an electrophysiologist may recommend radiofrequency ablation.
4. AVRT and WPW Syndrome
Atrioventricular re-entrant tachycardia can occur when an additional electrical connection is present between the heart’s upper and lower chambers.
Wolff-Parkinson-White syndrome is associated with this type of accessory pathway. It can cause sudden episodes of rapid heartbeat.
During an electrophysiology study, the specialist maps the abnormal connection. Ablation may be used to interrupt the pathway and prevent future rhythm episodes.
5. Atrial Flutter
Atrial flutter is caused by a rapid electrical circuit, commonly in the right atrium. The upper chambers contract rapidly, and the ventricles may also beat faster than normal.
Treatment can involve:
- Rate-control medication
- Rhythm-control medication
- Anticoagulation when indicated
- Electrical cardioversion
- Catheter ablation
Ablation may be an effective treatment for typical atrial flutter when appropriately recommended.
6. Atrial Tachycardia
Atrial tachycardia begins when an abnormal electrical focus within the atrium produces signals faster than the heart’s natural pacemaker.
It may occur intermittently or remain present for longer periods. Persistent atrial tachycardia can sometimes weaken heart function if it causes a continuously elevated heart rate.
A cardiac ablation specialist in Hyderabad can determine whether mapping and ablation may be appropriate.
7. Ventricular Tachycardia
Ventricular tachycardia is a rapid rhythm that begins in the heart’s lower chambers.
It can occur in patients with:
- Previous heart attack
- Cardiomyopathy
- Heart failure
- Scar tissue within the heart
- Inherited electrical disorders
- Structurally normal hearts in selected cases
Ventricular tachycardia can be serious and requires specialist evaluation. Depending on the cause and risk, treatment may include medicines, catheter ablation or an implantable cardioverter-defibrillator.
8. Bradycardia and Heart Block
Bradycardia means the heart is beating more slowly than expected. Heart block occurs when electrical signals are delayed or interrupted while travelling through the heart.
Possible symptoms include:
- Fatigue
- Dizziness
- Fainting
- Reduced exercise tolerance
- Breathlessness
- Confusion
- Weakness
A pacemaker may be recommended when a slow rhythm produces significant symptoms or creates a safety risk.
9. Unexplained Fainting
Fainting can have several causes, including blood-pressure changes, neurological conditions and abnormal heart rhythms.
When a rhythm disorder is suspected, evaluation may include:
- ECG
- Holter monitoring
- Extended event monitoring
- Echocardiography
- Implantable loop recorder
- Electrophysiology study
Identifying the cause is important because treatment varies considerably between different types of fainting.
Advanced Electrophysiology Treatments
Electrophysiology Study
An electrophysiology study, also known as EPS, is a specialised test that evaluates the heart’s electrical activity from inside the heart.
Thin catheters are passed through blood vessels and carefully guided into the heart. These catheters record electrical signals from different areas.
An EPS can help identify:
- Where an abnormal rhythm begins
- How electrical signals travel through the heart
- Whether an abnormal pathway is present
- Whether ablation may be suitable
- The possible risk of certain arrhythmias
In many cases, an electrophysiology study and catheter ablation can be performed during the same procedure.
3D Cardiac Mapping
Three-dimensional cardiac mapping creates a detailed representation of the heart’s electrical activity.
It allows an electrophysiologist to:
- Identify abnormal electrical signals
- Locate the origin of an arrhythmia
- Understand complex rhythm circuits
- Plan ablation more precisely
- Reduce unnecessary treatment of healthy tissue
3D mapping is particularly useful for atrial fibrillation, atrial tachycardia, ventricular tachycardia and arrhythmias that have returned after a previous procedure.
Radiofrequency Catheter Ablation
Radiofrequency ablation uses controlled energy to treat a small area of heart tissue responsible for producing or supporting an abnormal rhythm.
During the procedure:
- Catheters are guided into the heart.
- The electrical signals are recorded.
- The abnormal pathway or focus is identified.
- Controlled energy is delivered to the target area.
- The electrophysiologist tests whether the abnormal rhythm can still be produced.
The outcome depends on the type and location of the arrhythmia, associated heart disease and individual patient factors.
Atrial Fibrillation Ablation
Atrial fibrillation commonly begins with abnormal electrical activity near the pulmonary veins. AF ablation aims to electrically isolate these triggers from the rest of the atrium.
Ablation may be considered when:
- AF produces significant symptoms
- Medicines do not control the rhythm
- Medicines cause unacceptable side effects
- Maintaining a normal rhythm is clinically important
- AF contributes to worsening heart function
Not every patient with atrial fibrillation requires ablation. An individual assessment is necessary.
Pacemaker Implantation
A pacemaker is a small electronic device that helps regulate a heartbeat that is too slow or interrupted by heart block.
It usually consists of:
- A pulse generator
- One or more leads, depending on the device
- A programmed system that monitors the heartbeat
A pacemaker sends a small electrical impulse when it detects that the heart is beating too slowly.
Leadless Pacemaker
A leadless pacemaker is a compact device placed directly inside the heart without conventional pacing leads or a surgical pocket under the skin.
It may be suitable for selected patients depending on:
- The type of rhythm problem
- Required pacing pattern
- Heart anatomy
- Previous infections
- Vascular access
- Overall health
An electrophysiologist determines whether a leadless or conventional pacemaker is more appropriate.
ICD Implantation
An implantable cardioverter-defibrillator, or ICD, continuously monitors the heartbeat. If it detects a dangerous ventricular rhythm, it can deliver treatment to restore a safer rhythm.
An ICD may be considered for selected patients who have:
- Survived a life-threatening ventricular arrhythmia
- Significant heart weakness
- An increased risk of sudden cardiac death
- Certain inherited heart-rhythm conditions
Cardiac Resynchronisation Therapy
Cardiac resynchronisation therapy, or CRT, is used in selected patients with heart failure and electrical conduction delay.
CRT helps the ventricles contract in a more coordinated manner. In appropriately selected patients, this may improve symptoms, exercise capacity and heart function.
How Are Arrhythmias Diagnosed?
A normal ECG records only a short period of heart activity. If symptoms occur intermittently, the rhythm may appear normal during a clinic visit.
Depending on the symptoms, diagnosis may require:
- Resting ECG
- Holter monitoring
- Extended rhythm monitoring
- Event recorder
- Implantable loop recorder
- Echocardiogram
- Exercise stress test
- Blood tests
- Device interrogation
- Electrophysiology study
Patients should note when episodes occur, how long they last and whether they are associated with exercise, meals, stress, sleep, caffeine or medication.
How to Choose the Best Electrophysiologist in Hyderabad
There is no single doctor who is objectively best for every patient. The right electrophysiologist depends on the specific rhythm disorder and treatment required.
When selecting an arrhythmia specialist in Hyderabad, consider:
Specialised Electrophysiology Training
The doctor should have dedicated training in the diagnosis and treatment of electrical heart disorders.
Experience With Your Arrhythmia
Different arrhythmias require different approaches. Experience with the specific condition—such as SVT, atrial fibrillation, ventricular tachycardia or heart block—is important.
Experience With Ablation and 3D Mapping
When ablation is being considered, evaluate the specialist’s experience with electrophysiology studies, mapping technologies and different ablation procedures.
Cardiac-Device Expertise
For patients who may require a pacemaker, ICD or CRT device, look for experience in device selection, implantation, programming and long-term follow-up.
Hospital Infrastructure
Complex rhythm procedures should be supported by suitable catheterisation facilities, cardiac imaging, intensive care and emergency services.
Clear Communication
A good consultation should help the patient understand:
- The exact rhythm disorder
- Whether treatment is necessary
- Available treatment options
- Expected benefits
- Potential risks
- Alternatives to the procedure
- Follow-up requirements
Why an Accurate Rhythm Diagnosis Matters
Symptoms such as palpitations, dizziness or fainting can have many causes. Treating symptoms without documenting the underlying rhythm may delay the correct diagnosis.
An accurate diagnosis helps determine whether the patient needs:
- Reassurance and observation
- Lifestyle modifications
- Medication
- Cardioversion
- Catheter ablation
- A pacemaker
- An ICD
- CRT
- Further cardiac or neurological evaluation
The objective is not simply to reduce palpitations. It is to identify the rhythm, understand its risk and select the most appropriate treatment.
Frequently Asked Questions
Who is the best electrophysiologist in Hyderabad?
The best electrophysiologist for an individual patient depends on the type of arrhythmia, procedure required, medical history and hospital support needed. Dr. M.S. Chandramouli specialises in heart-rhythm disorders, cardiac ablation, 3D mapping, pacemakers, ICD, CRT and heart-failure care in Hyderabad.
Which doctor treats an irregular heartbeat?
A cardiologist can perform the initial evaluation. When an electrical rhythm disorder is diagnosed or suspected, a cardiac electrophysiologist is the specialist who focuses on abnormal heart rhythms.
Is cardiac ablation a major surgery?
Cardiac ablation is generally a minimally invasive catheter-based procedure rather than open-heart surgery. Catheters are passed through blood vessels to reach the heart. The exact procedure, anaesthesia and recovery depend on the type of arrhythmia being treated.
Can an arrhythmia be permanently cured?
Some rhythm disorders, particularly several types of SVT, can often be effectively treated by eliminating the abnormal electrical pathway. Outcomes vary between conditions, and some patients may require continued monitoring, medication or an additional procedure.
Does every patient with palpitations need ablation?
No. Palpitations can have many causes. Treatment depends on the documented rhythm, symptom severity, frequency of episodes, associated heart disease and individual patient preferences.
Is an electrophysiology study painful?
An EP study is normally performed with local anaesthesia and appropriate sedation. Patients may notice pressure at the access site or brief palpitations when the rhythm is tested. The medical team monitors the patient throughout the procedure.
When is a pacemaker required?
A pacemaker may be required when the heartbeat becomes too slow or electrical signals fail to travel normally through the heart. The decision depends on ECG findings, symptoms and the type of conduction problem.
Is a pacemaker the same as an ICD?
No. A pacemaker primarily treats abnormally slow heart rhythms. An ICD can recognise and treat certain dangerous rapid ventricular rhythms. Some devices combine pacing, defibrillation and resynchronisation functions.
Can atrial fibrillation cause a stroke?
Atrial fibrillation can increase stroke risk because blood may pool and form a clot in the upper chambers of the heart. Stroke risk varies between patients. An appropriate assessment determines whether anticoagulant medication is needed.
When should palpitations be treated as an emergency?
Seek urgent medical help if palpitations occur with chest pain, severe breathlessness, fainting, confusion, collapse or a sustained very rapid heartbeat.
