Sudden Cardiac Death – Understanding & Treatment
Sudden Cardiac Death (SCD) is a sudden, unexpected loss of heart function caused by a dangerous heart rhythm (arrhythmia). It is usually due to ventricular fibrillation, where the lower chambers of the heart quiver instead of pumping blood effectively.
At Fortis Hospital, Shalimar Bagh, Dr. Nityanand Tripathi, Principal Director & HOD – Cardiology & Electrophysiology, specializes in the prevention, evaluation, and advanced management of patients at risk of Sudden Cardiac Death.
What Causes Sudden Cardiac Death?
Several heart conditions increase the risk of SCD:
- Coronary Artery Disease and previous heart attack
- Heart failure with reduced ejection fraction
- Inherited heart rhythm disorders (e.g., Long QT syndrome, Brugada syndrome)
- Cardiomyopathies (hypertrophic, dilated, arrhythmogenic)
- Severe electrolyte imbalances
- Certain drug effects or toxin exposure
Emergency Treatment of Sudden Cardiac Arrest
Immediate action is critical:
- Cardiopulmonary Resuscitation (CPR): Starts blood circulation and oxygenation until advanced help arrives
- Automated External Defibrillator (AED): Delivers an electric shock to restore normal heart rhythm
- Advanced Life Support: Provided by emergency medical teams (medications, airway management, defibrillation)
- Hospital Care: Includes coronary angiography, angioplasty if needed, and intensive cardiac monitoring
Long-term Prevention & Treatment
- Implantable Cardioverter-Defibrillator (ICD / AICD): Recommended for patients at high risk of recurrent life-threatening arrhythmias. The device continuously monitors the heart and delivers a shock if a dangerous rhythm is detected.
- Medications: Beta-blockers, anti-arrhythmic drugs, and heart failure therapies to reduce risk
- Treatment of Underlying Conditions: Coronary revascularization, management of heart failure, and correction of reversible causes
- Lifestyle Measures: Heart-healthy diet, regular exercise (as advised), quitting smoking, and control of risk factors
Who is at High Risk of Sudden Cardiac Death?
- Patients with previous heart attack and reduced heart function
- Individuals with heart failure (low ejection fraction)
- Survivors of previous cardiac arrest
- Patients with certain inherited arrhythmia syndromes
- Those with significant cardiomyopathy
