Atrioventricular dissociation
MONDO:0008848Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the sinoatrial node and the right atrium (sa block) or between atria and ventricles (av block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.
Also known as: atrioventricular dissociation, atrioventricular dissociation (disease), A-V dissociation

New pacemaker technique aims to protect heart function
Disease control OngoingThis study compares a newer pacemaker method, left bundle branch area pacing (LBBAP), to the standard right ventricular pacing in 200 patients with heart block and normal heart function. The goal is to see if LBBAP better preserves the heart's pumping ability and reduces complica…

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 …

New antibiotic pouch aims to stop infections in heart device patients
Disease control OngoingThis study is tracking 100 adults who receive an EluPro antibiotic-eluting envelope during implantation of a heart device (like a pacemaker). The envelope slowly releases antibiotics to prevent infection. Researchers are monitoring complication rates in real-world use to see how …

New pacing technique may shield heart from damage in block patients
Disease control OngoingThis study tests if a newer pacing method called left bundle branch pacing (LBBP) is better than standard right ventricular pacing (RVP) at preserving heart function in 683 adults with atrioventricular block (a type of heart block). Participants will be randomly assigned to one o…

Wireless pacemaker takes on traditional device in heart study
Disease control OngoingThis study compares a new leadless pacemaker (Micra AV) to a standard dual-chamber pacemaker in 100 patients aged 70 and older with heart block. The goal is to see if the leadless version works just as well for exercise capacity. Participants are randomly assigned to receive one …

Tiny Pacemaker's position may change how heart beats
Knowledge-focused OngoingThis study watches 40 adults who need a leadless pacemaker to see if where the device sits inside the heart changes heart rhythm or pumping strength. Researchers will use CT scans and ECGs to check heart function and valve leakage. The goal is to find the best spot for the pacema…
