What are the warning signs of cardiac arrest?

Dr. Kristopher J. Selke, DO
Interventional Cardiologist

Typically, there are two major warning signs of sudden cardiac arrest in younger people. The first is exertional fainting episodes --  if you are exercising and passing out during exercise, you need to pay acute attention to this. The second thing that's important to look at is if there's a family history of people dying suddenly before the age of 50. If both these warning signs are present, follow up with your doctors for tests.

A person in cardiac arrest is unconscious, not breathing and has no heartbeat. The heart has either stopped beating or is beating weakly and irregularly so that a pulse cannot be detected.
