WebJan 27, 2024 · Asystole does not occur without a cause. An event, trauma, injury, or literal electrical shock may stun the cardiac muscle and lead to asystole. This is known as secondary asystole. Asystole may also occur from a failure of the electrical nodes in the heart to generate an action potential (contraction), known as primary asystole. WebTo pump the blood, the heart uses an electrical conduction system composed of nodes and conducting fibers. The sinoatrial node, or SA node, which is a group of pacemaking cells in the myocardium of the right atrium, produces an electrical impulse that travels through the heart in specific pathways causing it to contract.
