Methods The TriNetX database (Jan 2015June 2023) was queried to include adults receiving their first single-chamber ventricular pacemaker for heart block, bradycardia, sick sinus syndrome, atrial fibrillation, or syncope, excluding those with prior pacemakers, heart failure or enrolled for research settings.

ABSTRACT Introduction Leadless pacemakers (LPs) are a valuable treatment for bradycardia, with the Aveir offering advanced features, including a protective sleeve and active fixation. The higher impedance during the implantation was a strong predictor of a midterm favorable PCT.

Abstract Introduction Severe transitory episodes of bradycardia with subsequent syncope in children are common, and generally portend a benign prognosis. Rarely, patients may experience prolonged asystolic episodes secondary to significant sinus pauses (SP) or paroxysmal atrioventricular block (AVB).

There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Torsades in acquired long QT is much more likely in bradycardia because the QT interval following a long pause is longer still. The corrected QT interval is extremely long, about 500 ms.

PVCs N ot generally considered abnormal ECG findings: Isolated PAC, First Degree AV Block, Sinus bradycardia at a rate of 35-45, and Nonspecific ST-T abnormalities (even if different from a previous ECG). Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.
