Web28 de mar. de 2024 · The sinoatrial node, better known as the sinuatrial or SA node is the key structure responsible for the generation of a regular heartbeat and is therefore often referred to as the pacemaker of the heart. It is the first component of the cardiac conduction system and is composed of specialized cardiac muscle cells, which are … WebThe conduction system of the heart. Left: Normal excitation originates in the sinoatrial (SA) node then propagates through both atria. The atrial depolarization spreads to the atrioventricular (AV) node, and passes through the bundle of His to the bundle branches/Purkinje fibers.
WebAnimal studies demonstrate that hypokalemia-induced arrhythmogenicity is attributed to prolonged ventricular repolarization, slowed conduction, and abnormal pacemaker activity. The prolongation of ventricular repolarization in hypokalemic setting is caused by inhibition of outward potassium currents and often associated with increased propensity for early … WebHow does your heart keep its rhythm?
