A Complete Patient Awareness Guide by Dr. M.S. Chandramouli Introduction: When a Fast Heartbeat Becomes Dangerous A racing heart can be frightening. Many people experience sudden episodes where their heart starts beating unusually fast — sometimes reaching 150–250 beats per minute. While this can happen due to stress or exercise, in some cases, it […]
Atrial fibrillation (AF) is one of the most common rhythm disorders seen in cardiology practice. For patients whose symptoms continue despite medicines, pulmonary vein isolation (PVI) can play an important role in restoring rhythm control. This blog explains AF in simple language and walks readers through a real-world cryoablation-based PVI case shown in the uploaded […]
A Comprehensive Guide to Hardware and Tools for Safe Transvenous Lead Extraction Cardiology | Electrophysiology | Device Management Introduction Cardiac implantable electronic devices (CIEDs)—including pacemakers, implantable cardioverter-defibrillators (ICDs), and cardiac resynchronization therapy (CRT) devices—have revolutionised the management of cardiac arrhythmias and heart failure worldwide. As global implantation rates continue to climb, so too does […]
Understanding the Purpose of an ICD An ICD is a life-saving device implanted in patients at risk of: Sudden Cardiac Arrest (SCA) Ventricular Tachycardia (VT) Ventricular Fibrillation (VF) Severe cardiomyopathy with low ejection fraction The device continuously monitors heart rhythm and delivers: A shock to terminate life-threatening arrhythmias Anti-tachycardia pacing (ATP) in selected devices Backup […]
Atrial arrhythmias in patients with prior coronary artery bypass grafting (CABG) can be complex, challenging, and often recurrent. Scar-related circuits, atrial remodeling, and structural heart disease make diagnosis and management significantly more demanding. This case highlights an atypical left atrial (LA) flutter successfully diagnosed and treated using advanced electrophysiological study (EPS), high-density (HD) mapping, and […]
Most people experience heart palpitations at least once in their life. It may feel like your heart is racing, fluttering, skipping a beat, or pounding harder than usual. Often, it happens suddenly—during rest, after exercise, or even while lying quietly in bed at night. For many, palpitations are harmless and temporary. But in some cases, […]
Atrial flutter is often perceived as a straightforward arrhythmia, especially when it involves the cavotricuspid isthmus (CTI). However, atypical atrial flutter, particularly in the presence of atrial scar, presents a far more complex diagnostic and therapeutic challenge. Accurate identification of the re-entrant circuit is essential to ensure durable procedural success. This case highlights the role […]
A Detailed Case-Based Explanation Abnormal heart rhythms (arrhythmias) can significantly affect quality of life and, in some cases, pose serious health risks. One such rhythm disorder is Focal Atrial Tachycardia (AT)—a condition where rapid heartbeats originate from a specific abnormal focus within the atria rather than the heart’s normal pacemaker. This blog presents a real-world […]
Heart failure is often misunderstood as a condition where the heart becomes weak and cannot pump blood effectively. While this is true for many patients, there is an important and increasingly common form of heart failure where the heart’s pumping function appears normal on tests. This condition is called Heart Failure with Preserved Ejection Fraction […]
A Case was led by Dr. M. S. Chandramouli, Senior Electrophysiologist, from Yashoda Hospitals, Secunderabad Abnormal heart rhythms can significantly impact a patient’s quality of life—especially when they occur after a heart attack. This case highlights the successful diagnosis and treatment of focal atrial tachycardia (AT) using advanced electrophysiology study (EPS) and 3D-guided radiofrequency ablation […]
