WebSep 15, 2024 · Many stimulants act via catecholaminergic augmentation, resulting in β-receptor stimulation, shortened atrial effective refractory period, increased cAMP (cyclic adenosine monophosphate), cytosolic calcium, atrial automaticity, and pulmonary vein ectopic depolarizations. 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 ...

WebIncreased automaticity occurs both in the atria and the ventricles. This initially manifests with premature beats (premature atrial beats or premature ventricular beats ), which are considered an early sign of overdosing. At higher plasma levels atrial tachyarrhythmias and ventricular tachyarrhythmias may occur.
