What is the cause of agonal rhythms?

Question

Quizplus · Accepted Answer

Agonal rhythms occur due to the failure of all pacemakers of the heart, resulting in a disorganized and irregular electrical activity. This can be caused by various factors such as cardiac arrest, severe hypoxia, and other critical conditions leading to inadequate perfusion to the heart. Failure of the SA node or blocked conduction at the AV node may lead to specific arrhythmias, but not necessarily agonal rhythms. Loose electrode wires may cause artifact or interference in the ECG, but not agonal rhythms.
