What Is a Sudden Cardiac Arrest?

Sudden cardiac arrest is a condition in which the person is unresponsive and his/her heart stops beating due to an irregular rhythm. Sudden cardiac arrest can lead to sudden cardiac death if the emergency care is not initiated within the first few minutes. Sudden cardiac death is the most common cause of natural deaths. This is responsible for more than half of death by cardiac diseases.

There can be few differences between a sudden cardiac arrest and a heart attack. Heart attack is also known as myocardial infarction, this is when one or two coronary arteries are blocked. This will lead to reduced blood flow to the heart. When the heart doesn’t get enough blood it doesn’t get enough oxygen which can damage the heart muscle.

Sudden cardiac arrest is when the electrical system of the heart has a problem and the rhythm of the heart changes. This irregular rhythm can cause the heart to beat too fast sometimes. This can be insufficient for the flow of blood to all the organs. The blood flow to the brain will be seized as well. This is when the person loses his conciseness or become unresponsive. This can lead to sudden death if emergency treatment is not performed.

Emergency treatment in this case consists of CPR (cardio pulmonary resuscitation) and defibrillation. The CPR helps to keep oxygen in the lungs till a shock is delivered by defibrillators to store the cardiac rhythm. There are portable defibrillators these days. It’s best to get defibrillator for sale and keep it in your house. More than 80% of sudden cardiac arrest occurs at home.

  • Ventricular fibrillation or tachycardia
  • Coronary artery disorders
  • Family history of abnormal heart rhythm
  • Congenital heart diseases
  • Heart failure
  • Cardiomyopathies
  • Diabetes mellitus
  • Obesity

Causes

The mostly common causes of cardiac arrest are malfunction of the electrical system of the heart causing irregular rhythm. Two most common pathologies are atrial fibrillation and ventricular fibrillation.

Management
