Cardiac Causes:
Coronary Artery Disease (CAD) – the most common underlying cause.

Heart Failure
Ventricular Arrhythmias like ventricular tachycardia (VT) and ventricular fibrillation (VF)

Congenital Heart Defects

Cardiomyopathies (e.g., hypertrophic, dilated)

Electrical conduction disorders (e.g., Long QT syndrome, Brugada syndrome)

Non-Cardiac Causes:

• Severe electrolyte imbalances
• Respiratory arrest
• Pulmonary embolism
• Drug overdose or poisoning
• Trauma or injury to the chest

Who is at Risk?
Certain factors increase the likelihood of sudden cardiac arrest, including:

• Previous history of heart disease
• Family history of sudden cardiac death
• Smoking or excessive alcohol consumption
• Obesity or sedentary lifestyle
• High blood pressure, diabetes, or high cholesterol
• Use of stimulant drugs or certain medications
• Stress and anxiety disorders

Men over 45 years old and individuals with poorly managed heart conditions are particularly vulnerable.

Types of Cardiac Arrest (Based on ECG Rhythm)

• Ventricular Fibrillation (VF) – disorganized heartbeat
• Pulseless Ventricular Tachycardia (VT) – fast, ineffective rhythm
• Pulseless Electrical Activity (PEA) – electrical signals without actual pumping
• Asystole – complete absence of heart activity (flatline)

How is Cardiac Arrest Diagnosed?
During a cardiac arrest emergency, diagnosis is primarily clinical:

• No pulse or breathing
• Unconsciousness
• Dilated, unresponsive pupils

To determine the cause post-resuscitation, Dr. Sudhakar Reddy may use:

• Electrocardiogram (ECG)
• Echocardiography
• Blood tests for potassium, magnesium, and cardiac enzymes
• Cardiac imaging
• Coronary angiography, if required

Immediate Treatment of Cardiac Arrest  At Sridhaa Clinic, we follow evidence-based protocols for cardiac emergencies. Treatment involves:

1. CPR (Cardiopulmonary Resuscitation):
   Early chest compressions to maintain circulation.
2. Defibrillation:
   An electric shock to restore normal rhythm, using an Automated External Defibrillator (AED).
3. Advanced Life Support (ALS) :
   IV medications, oxygen support, airway management, and continuous monitoring.
4. Post-Resuscitation Care:
   Targeted temperature management

Cardiac catheterization

Neurological assessment

Long-Term Management After Cardiac Arrest
Survivors of cardiac arrest require a comprehensive heart health plan:

• Implantable cardioverter-defibrillators (ICDs)
• Medication management (beta-blockers, antiarrhythmics)
• Lifestyle changes (smoking cessation, weight loss, stress control)

Cardiac rehabilitation programs

At Sridhaa Heart & Endocrine Super Specialty Clinic, Dr. Sudhakar Reddy tailors individualized care plans to prevent recurrence and improve heart function.

Prevention of Cardiac Arrest

• Simple Lifestyle Changes Can Save Lives: Eat a heart-healthy diet rich in fruits, vegetables, and whole grains.
• Engage in regular physical activity.
• Quit smoking and limit alcohol consumption.
• Manage stress effectively.
• Control underlying conditions like hypertension, diabetes, and high cholesterol.
• Attend regular heart check-ups, especially if there’s a family history of heart disease.
