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
43 clinical trials for this condition and its sub-types, 10 tagged with Third-degree atrioventricular block itself.

New pacemaker approach could reduce heart failure risk
Disease control Recruiting nowThis study compares two pacemaker methods for people with a slow heart rate: standard right ventricular pacing and a newer 'physiological pacing' that targets the heart's natural conduction system. Researchers will track 2,600 participants over time to see which method better pre…

New pacemaker technique may cut AF risk in heart patients
Disease control Recruiting nowThis study compares two ways of placing a pacemaker lead in people who need frequent pacing. One method (left bundle branch pacing) aims to activate the heart more naturally than the standard method. The goal is to see if it reduces the time the heart spends in fast, irregular rh…

New pacemaker promises longer battery, better heart rhythm
Disease control Recruiting nowThis study tests a new, smaller pacemaker called Micra AV2 in 150 adults with heart block (a condition where the heart's electrical signals are blocked). The pacemaker is designed to better match the heart's natural rhythm, especially during exercise, and lasts over 15 years. Res…

Pacemaker showdown: which new technology is safer for your heart?
Knowledge-focused Recruiting nowThis study will compare two newer pacemaker technologies—left bundle branch area pacing and leadless pacing—to see how they affect heart function and the tricuspid valve. Twenty adults with certain heart block conditions will receive both types temporarily during their routine pa…
