WitrynaConduction of the impulse to bundle of His 3. When SA node fails to act as pacemaker, it can take up the function of pacemaker, but at a decreased rate of impulse production. The nodal delay does not permit the impulse that has reached the AV node from SA node to get conducted immediately. The normal delay in the AV node is about 0.1 sec. WitrynaThe conduction system is functionally developed at 16 weeks of gestation. The components of the cardiac electrical conduction system are: 1) the SN, 2) the AV node, and 3) the His–Purkinje system. The role of this system is to generate and propagate the electrical impulse through the myocardium to produce each heartbeat.

Witryna12 mar 2024 · The electrical impulse originates in the sinus node. From there, it spreads across the right atrium and the left atrium (the top two chambers of the heart), causing both atria to contract. This is referred to as atrial depolarization, an action that pushes blood into the right and left ventricles, the bottom two chambers of the heart. 5 exophytic cyst on ovaryWitrynaThe interruption of the cardiac conduction system that occurs in the ventricles, anatomically after the electrical impulse leaves the atrioventricular node, generates bundle branch block.
