Cardiac arrest is a sudden and life-threatening medical emergency in which the heart unexpectedly stops beating effectively, leading to an immediate loss of blood flow to the brain and vital organs. Understanding what is cardiac arrest is critical, as survival depends on rapid recognition and emergency treatment.

Unlike a heart attack, cardiac arrest occurs due to an electrical malfunction in the heart that causes abnormal heart rhythms. Without immediate cardiac arrest treatment, the condition can result in death within minutes. Prompt medical care at our specialised heart hospital in Delhi NCR significantly improves survival outcomes.

Symptoms of Cardiac Arrest

• Sudden collapse
• Loss of consciousness
• No pulse or breathing
• Chest discomfort before collapse in some cases
• Dizziness or fainting
• Shortness of breath
• Sudden extreme weakness

Cardiac Arrest Causes

• Abnormal heart rhythms (arrhythmias)
• Coronary artery disease
• Previous heart attack
• Cardiomyopathy
• Severe electrolyte imbalance
• Drug overdose
• Trauma or severe injury

Diagnosis of Cardiac Arrest

Accurate and timely diagnosis of cardiac arrest is crucial for identifying the cause, guiding emergency treatment, and planning further care to reduce complications and support effective cardiac arrest prevention strategies.

• Clinical Assessment: Immediate evaluation of consciousness, pulse, breathing, and heart rhythm to confirm cardiac arrest.

• Electrocardiogram (ECG) : Identifies abnormal heart rhythms responsible for cardiac arrest.

• Blood Tests: Assess electrolyte levels, cardiac enzymes, and underlying metabolic conditions.

• Echocardiography: Evaluates heart structure and pumping function after resuscitation.

• Coronary Angiography: Identifies blocked arteries in cases of cardiac arrest related to coronary artery disease.

Treatment Options & Technology for Cardiac Arrest

Cardiac arrest treatment focuses on rapid resuscitation, stabilisation, and advanced cardiac care to restore heart function, prevent recurrence, and improve survival outcomes under expert supervision from our heart specialist in Delhi NCR.

• Cardiopulmonary Resuscitation (CPR) : Immediate CPR maintains blood flow to vital organs until advanced care is available.

• Defibrillation: Electrical shock restores normal heart rhythm in patients with life-threatening arrhythmias.

• Advanced Cardiac Life Support (ACLS) : Includes medications, airway management, and continuous monitoring in critical care settings.

• Post-Resuscitation Care : Intensive monitoring, temperature control, and organ support after revival.

• Implantable Cardiac Devices : Devices such as implantable cardioverter-defibrillators (ICDs) prevent future cardiac arrest in high-risk patients.

Prevention & Lifestyle Modifications for Cardiac Arrest

• Control Blood Pressure, Diabetes, and Cholesterol: Proper management lowers the risk of heart disease and sudden cardiac events.

• Quit Smoking and Limit Alcohol Consumption: Avoiding tobacco and excessive alcohol helps protect heart function and blood vessels.

• Maintain a Heart-Healthy Diet: A balanced diet rich in fruits, vegetables, and whole grains supports cardiovascular health.

• Engage in Regular Physical Activity: Moderate exercise improves circulation, strengthens the heart, and reduces risk factors.

• Manage Stress Effectively: Stress control techniques help prevent blood pressure spikes and heart strain.

• Take Prescribed Heart Medications Regularly: Adhering to medications ensures better heart rhythm control and risk reduction.

• Attend Routine Cardiac Check-Ups: Regular evaluations help detect early issues and support long-term cardiac arrest prevention.
