	'''Pulseless Electrical Activity (PEA)''' is an electrocardiographic finding characterized by the presence of cardiac electrical activity without an adequate mechanical response from the myocardial tissue, resulting in no effective cardiac output or palpable pulse. Despite the presence of electrical rhythms on the ECG, the heart fails to pump blood effectively, leading to a critical condition that requires immediate medical intervention.

	PEA can be caused by a variety of conditions that can be categorized into ''hypovolemic, hypoxic, hydrogen ion (acidosis), hyper-/hypokalemia, hypothermia, toxins, tamponade (cardiac), tension pneumothorax, thrombosis (coronary or pulmonary), and trauma'' (the "H's and T's"). Each of these conditions can lead to the disruption of cardiac function, resulting in PEA.

== Introduction ==
'''Pulseless Electrical Activity (PEA)''' is an electrocardiographic finding characterized by the presence of cardiac electrical activity without an adequate mechanical response from the myocardial tissue, resulting in no effective cardiac output or palpable pulse. Despite the presence of electrical rhythms on the ECG, the heart fails to pump blood effectively, leading to a critical condition that requires immediate medical intervention.
