Reentrant Arrhythmias. [Review]
Citation: StatPearls Publishing. 2020 01PMID: 32491707Department: MedStar Health Baltimore ResidentsForm of publication: Journal ArticleMedline article type(s): ReviewSubject headings: IN PROCESS -- NOT YET INDEXEDYear: 2020Abstract: Reentrant arrhythmias are distinct electrophysiology maladies of the heart caused by the presence of circuits in the normal myocardium. Atrioventricular nodal reentry tachycardia (AVNRT), the most common reentrant supraventricular tachycardia (SVT), utilizes the AV node as its circuit.[1] Other reentrant tachycardias such as Wolff-Parkinson White (WPW) syndrome, utilizes an accessory pathway to create the reentrant circuit. Reentry occurs when the propagating electrophysiological signal fails to succumb to its normal continuance and persists, re-exciting the heart after the refractory period. This constant re-excitation of the heart can produce a heart rate of over 250 beats per minute. However, the typical range is usually 180 to 200 beats per minute in adults. Occasionally, hypotension can occur with prolonged episodes at a rapid ventricular rate.
