Objective The purpose of this study was to investigate the hypothesis that abnormal Ca i dynamics are responsible for triggered activity in the pulmonary veins (PVs) during acetylcholine infusion in a canine model of heart failure. … Webcircus movement tachycardia (CMT) a reentry circuit that uses an accessory pathway or pathways; there are two subtypes, antidromic and orthodromic circus movement …
Re-entry ventricular arrhythmia is a type of paroxysmal tachycardia occurring in the ventricle where the cause of the arrhythmia is due to the electric signal not completing the normal circuit, but rather an alternative circuit looping back upon itself. There develops a self-perpetuating rapid and abnormal activation. ("Circus Movement" is another term for this.) Conditions necessary for re-entry include a combination of unidirectional block and slowed conduction.

WebPacemaker Circus Movement Tachycardia. The reentry tachycardia occasionally seen in patients with normally functioning DDD, DDR, or VDD pacemakers is sometimes also called endless-loop tachycardia (ELT). 37–39 The underlying cause of this pacemaker-induced tachycardia is the presence of retrograde P waves (Figures 26-27 and 26-28). greenville healthcare associates txWebSupraventricular tachycardia (SVT) is an umbrella term for fast heart rhythms arising from the upper part of the heart.
