What is Sudden Cardiac Arrest?

  • Sudden cardiac arrest is an electrical disturbance in the heart that disrupts the heart’s pumping and stops blood flow to the body.

  • The most common arrhythmia at the time of cardiac arrest is ventricular fibrillation, where the lower chambers of the heart quiver erratically instead of pump blood.

  • There are many conditions that can lead to sudden cardiac arrest such as coronary artery disease, heart attack, cardiomyopathy, valvular heart disease, congenital heart disease, and primary heart rhythm abnormalities (

  • Some people who suffer from sudden cardiac arrest have no previous conditions and a cause is never found.
