Cardiac Arrests: Causes, Symptoms, and Treatments

It is a common mistake to interchange cardiac arrest and heart attack. Cardiac arrest strikes immediately or could be a result of a cardiovascular defect. Although it is a very serious heart condition, there are certainly ways to treat it as well as get educated on its symptoms.

What is cardiac arrest?

Cardiac arrest is a sudden loss of cardiac function in a human who might or might not suffer from heart disease. It appears unexpectedly or followed by earlier illnesses. If the absence of blood supply to the brain and other organs is not addressed right away, a person might lose consciousness, become paralyzed, or face death.

What is the difference between cardiac arrest and a heart attack?

Heart attacks and cardiac arrest are two separate heart disorders, despite the fact that the terms are frequently used interchangeably. A clog in the arteries that prevents blood flow to the heart causes a heart attack. As those heart attacks can alter the electrical impulses in the heart, they might raise the chance of cardiac arrest as well as destroy heart muscle tissue. Once cardiac arrest arises unexpectedly followed by no particular existing heart dysfunction, in most cases it is a result of a heart attack.

Causes and risk factors of cardiac arrest

Cardiac arrest can occur spontaneously or be brought on by a cardiovascular disease. There are three primary causes of cardiac arrest, though:

  • Ventricular fibrillation and arrhythmia: An arrhythmia develops after faulty electrical impulses in the cardiac core cause an irregular heartbeat. The most typical arrhythmia and the trigger of cardiac arrest is ventricular fibrillation. A fast beating in the ventricle of the heart, or ventricular fibrillation, forces the heart to flutter instead of circulating blood properly.
  • Enlarger heart: Heart disease that stands for heart's muscle to enlarge or thicken.
  • Coronary artery disease: It develops once the coronary arteries become thickened and constricted due to plaque buildup, thereby it reduces blood supply to the heart. Coronary artery disease might lead to heart problems or arrhythmias, either of which could result in cardiac arrest if ignored and untreated.

Cardiac arrest symptoms

Although, there could be absolutely no indications of cardiac arrest in some circumstances, these signs could be present before a cardiac arrest:

  • Fainting
  • Fatigue
  • Breathing difficulty
  • Vomiting
  • Chest discomfort
  • Heart flutters (rapid or pounding heart beat)
  • Consciousness reduction

Some symptoms of cardiovascular arrest can be fatal.

How is cardiac arrest treated?

In order for their organs to receive more oxygen-rich blood, those who experience cardiac arrest require urgent medical care, two of which are described below:

Cardiopulmonary resuscitation (CPR)

Cardiopulmonary resuscitation (CPR) involves having someone else pressing on the chest to enhance blood circulation to the organs, is frequently the primary course of treatment. Until more sophisticated emergency care is provided to the individuals undergoing cardiac arrest, CPR can treat cardiac arrest momentarily.


Whenever emergency cardiovascular experts arrive, a defibrillator will be used to stimulate the heart by shocking it with electricity, which will restore its features and begin proper circulation.
