Arrhythmias caused by abnormal automaticity can result from diverse mechanisms (see Figs. 6.1 and 6.2). Alterations in sinus rate can be accompanied by shifts of the origin of the dominant …
WebSinus tachycardia is the most common tachyarrhythmia (tachycardia). Sinus tachycardia is the result of an increased rate of depolarization (i.e increased automaticity) in the sinoatrial node. This simply means that the sinoatrial node discharges electrical impulses at a higher frequency than normal. Similar to sinus rhythm, the rhythm is ... WebSep 27, 2024 · Automaticity: the ability to spontaneously depolarize and generate an action potential. Conduction: movement of a cardiac action potential from one part of the heart to another. Contractility: the potential to do work, often measured as the ability of muscle tissue to develop tension or shorten.
