Understanding Pulseless Electrical Activity (PEA): Causes & Survival

Yes, it's possible to have a heartbeat but no pulse. This condition is called pulseless electrical activity (PEA). Although pulseless electrical activity appears life threatening, some people survive an initial PEA episode.

This can occur when the heart's electrical system is functioning, causing the heart to beat, but the contractions are too weak to produce a measurable pulse. This condition is commonly caused by a very damaged myocardium, such as in the later stages of a cardiac arrest event, and is often fatal if not treated promptly.

In pulseless electrical activity, cardiac output is absent or inadequate, meaning the heart is not pumping enough oxygenated blood to the rest of the body. Treatment for pulseless electrical activity typically involves cardiopulmonary resuscitation (CPR) and medications to improve heart function.
