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

Smart patches could save hearts: hospital trial tests continuous monitoring
Disease control Not yet recruitingThis study tests whether a wearable monitoring system (ECG patch, temperature patch, and pulse oximeter) can reduce major heart complications in hospitalized patients with heart disease. About 1500 adults will be monitored either with standard care (vital signs every 4-8 hours) o…

Could heart and muscle disorders share a genetic cause?
Knowledge-focused Not yet recruitingThis study looks at whether people with certain heart rhythm disorders also carry genetic variants linked to a rare muscle condition called non-dystrophic myotonia. Researchers will review medical records of 570 participants and invite some for a neurological exam and electromyog…
