Sudden Cardiac Arrest : Causes, Conditions and How To Prevent It

Sudden cardiac arrest (SCA) is the sudden loss of all heart activity due to an irregular heart rhythm. Breathing stops. The person becomes unconscious. Without immediate treatment, sudden cardiac arrest can lead to death.

Crisis treatment for unexpected heart failure incorporates cardiopulmonary revival (CPR) and shocks to the heart with a gadget called a mechanized outer defibrillator (AED). Endurance is conceivable with quick, proper clinical consideration.


Symptoms of sudden are immediate and severe and include:

  • Sudden collapse.
  • No pulse.
  • No breathing.
  • Loss of consciousness.

Sometimes other symptoms occur before sudden cardiac arrest. These might include:

  • Chest discomfort.
  • Shortness of breath.

When to see a doctor

When the heart stops, the lack of oxygen-rich blood can quickly cause death or permanent brain damage. On the off chance that you see somebody who’s oblivious and not breathing, call 911 or nearby crisis administrations. Then, at that point, begin CPR. The American Heart Affiliation suggests performing mouth-to-mouth with immovable chest compressions.

In the event that you haven’t been prepared, simply proceed with chest compressions. Permit the chest to rise totally between compressions. Continue to do this until an AED is accessible or crisis laborers show up.

Versatile robotized outside defibrillators, called AEDs, are accessible in numerous public spots, including air terminals and shopping centers.


Electric signs in the heart control the rate and beat of the heartbeat. Broken or extra electrical signs can make the heart beat excessively quickly, too leisurely, or in a clumsy way. Changes in the heartbeat are called arrhythmias. A few arrhythmias are brief and innocuous. Others can prompt abrupt heart failure.

Heart conditions that can lead to sudden cardiac arrest

The most well-known reason for abrupt heart failure is an unpredictable heart cadence called ventricular fibrillation. Quick, whimsical heart signals make the lower heart chambers tremble pointlessly as opposed to siphoning blood.

  • Coronary artery disease. Sudden cardiac may occur if the heart arteries become clogged with cholesterol and other deposits, reducing blood flow to the heart.
  • Heart attack. If a heart attack occurs, often as a result of severe coronary artery disease, it can trigger ventricular fibrillation and sudden cardiac arrest
  • Heart valve disease. Leaking or narrowing of the heart valves can lead to stretching or thickening of the heart muscle. When the chambers become enlarged or weakened because of stress caused by a tight or leaking valve.

Risk factors

The same things that increase the risk of heart disease can raise the risk of sudden cardiac arrest. These include:

  • A family history of coronary artery disease.
  • Smoking.
  • High blood pressure.
  • High blood cholesterol.
  • Obesity.


Keeping the heart healthy may help prevent sudden cardiac arrest. You can do this by:

  • Eating healthy.
  • Getting regular checkups.
  • Not smoking or using tobacco.
  • Being screened for heart disease.
