Full Form of PEA

What is PEA?

Pulseless Electrical Activity (PEA) is a cardiac arrest rhythm where the heart's electrical system continues to generate organized electrical impulses, but the heart muscle fails to contract effectively to produce a palpable pulse. In simpler terms, the ECG may show a rhythm that appears normal, yet there is no mechanical pumping of blood. PEA is a common initial rhythm in cardiac arrest, particularly in cases of hypoxia, hypovolemia, tension pneumothorax, cardiac tamponade, acidosis, or drug overdose. In Indian healthcare settings, especially emergency departments and ICUs, recognizing PEA promptly is critical because the treatment is not defibrillation but rather the identification and correction of reversible causes (often remembered as the 'Hs and Ts'). The term is widely used in ACLS (Advanced Cardiac Life Support) training across India by bodies like the American Heart Association or Indian equivalents. For medical students preparing for NEET PG, AIIMS, or nursing exams, understanding PEA is essential for cardiology and emergency medicine questions. Unlike ventricular fibrillation, PEA requires a focused search for underlying triggers, making it a high-stakes scenario requiring rapid clinical reasoning.

Example

The patient arrived in cardiac arrest, and the monitor revealed PEA; the team immediately started chest compressions and administered epinephrine while checking for reversible causes like hypoxia and hypovolemia.
