Mechanisms of Cardiac Arrhythmia Thoracic Key

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 14, 2024 · What causes increased automaticity? The automaticity in the sinoatrial node increases during physical exercise. The increased automaticity is a normal reaction since the cardiac output must increase during exercise. This is an example of normal (physiological) increase in automaticity.
