Third-degree atrioventricular block
MONDO:0000468A disorder characterized by an electrocardiographic finding of complete failure of atrial electrical impulse conduction to the ventricles. This is manifested on the ECG by disassociation of atrial and ventricular rhythms. The atrial rate must be faster than the ventricular rate. (CDISC)
Also known as: AV block third degree, atrioventricular block complete, atrioventricular block, third degree, complete AV block, complete atrioventricular block, complete heart block, non-congenital complete atrioventricular block, third degree AV block
42 clinical trials for this condition and its sub-types, 10 tagged with Third-degree atrioventricular block itself.

New pacemaker technique aims to prevent heart damage
Disease control OngoingThis study compares a newer pacing method called left bundle branch area pacing (LBBAP) with standard right ventricular pacing in 100 adults who need a pacemaker but have normal heart function. The goal is to see if LBBAP better prevents the decline in heart pumping ability that …

TAVR pacemaker study withdrawn before enrolling any patients
Knowledge-focused CancelledThis study was designed to compare a newer pacing method (left bundle branch area pacing) with the standard method (right ventricular pacing) in patients who developed heart block after TAVR valve replacement. The goal was to see which method better preserves heart function and r…
