Sudden Cardiac Arrest (SCA)

Overview

Sudden Cardiac Arrest (SCA) is a life-threatening emergency in which the heart suddenly stops beating effectively due to an abnormal electrical rhythm. This causes an immediate loss of blood flow to the brain and other vital organs.

SCA is different from a Heart Attack, although a heart attack can trigger cardiac arrest. Without immediate intervention, sudden cardiac arrest can lead to death within minutes.

At Moolchand Hospital, a leading multi super speciality hospital in Delhi, patients receive rapid emergency response, advanced life support, and comprehensive cardiac care.

What is Sudden Cardiac Arrest?

Sudden cardiac arrest occurs when the heart’s electrical system malfunctions, causing dangerous arrhythmias such as ventricular fibrillation or ventricular tachycardia. The heart is unable to pump blood effectively, leading to collapse.

Symptoms

SCA occurs suddenly and often without warning.

Immediate Signs

• Sudden collapse
  
  

• Loss of consciousness
  
  

• No pulse
  
  

• No breathing
  
  

Possible Warning Signs (before event)

• Chest discomfort
  
  

• Shortness of breath
  
  

• Palpitations
  
  

• Dizziness
  
  

Immediate action is critical to save life.

Causes

Common causes include:

• Coronary artery disease
  
  

• Previous heart attack
  
  

• Cardiomyopathy
  
  

• Severe arrhythmias
  
  

• Electrolyte imbalance
  
  

• Congenital heart conditions
  
  

Risk Factors

Risk factors include:

• History of heart disease
  
  

• High blood pressure
  
  

• High cholesterol
  
  

• Smoking
  
  

• Diabetes
  
  

• Family history of sudden cardiac death
  
  

What to Do in an Emergency

Immediate response can save life:

1. Call emergency services immediately
   
   

2. Start CPR (cardiopulmonary resuscitation)
   
   

3. Use an automated external defibrillator (AED) if available
   
   

Early intervention significantly improves survival.

Diagnosis

After stabilization, evaluation includes:

• Electrocardiogram (ECG)
  
  

• Blood tests
  
  

• Echocardiography
  
  

• Coronary angiography
  
  

• Electrophysiology studies
  
  

At Moolchand Hospital Delhi, rapid emergency protocols ensure timely diagnosis and treatment.

Treatment

Treatment involves both emergency and long-term care.

Emergency Treatment

• CPR
  
  

• Defibrillation (shock to restore normal rhythm)
  
  

• Advanced cardiac life support
  
  

Hospital Care

• Medications
  
  

• Treatment of underlying cause
  
  

Long-Term Management

• Implantable cardioverter-defibrillator (ICD)
  
  

• Lifestyle modifications
  
  

• Ongoing cardiac monitoring
  
  

Specialists at Moolchand Hospital Lajpat Nagar provide comprehensive post-arrest care and rehabilitation.

Complications

If not treated immediately, SCA may lead to:

• Brain damage
  
  

• Organ failure
  
  

• Death
  
  

Even with treatment, delayed response can cause long-term complications.

Prevention

Preventive measures include:

• Regular heart check-ups
  
  

• Managing risk factors (BP, cholesterol, diabetes)
  
  

• Avoiding smoking
  
  

• Timely treatment of heart conditions
  
  

• Screening in high-risk individuals
