The QRSs are wider than and different from other QRSs, raising a possibility of PVC. But they are clearly preceded by a prematurely occurring P wave and so are PAC with aberrant conduction. Aberrant ...

Cardiac physiologic pacing, also known as cardiac resynchronization therapy, is indicated in patients with heart failure, reduced left ventricular ejection fraction (LVEF) of 50% or less, and either a ...

Given today's short hospital stays after transcatheter aortic valve replacement (TAVR), there may be a role for selective long-term monitoring to flag delayed conduction abnormalities, studies showed.

The correct diagnosis is sinus rhythm, nonconducted premature atrial complexes (PACs), and junctional escape complex (Figure 2). The rhythm is irregular, but the long intervals are all the same (↔) ...

A novel bipolar conduction system pacing implantable cardioverter defibrillator lead demonstrated short-term safety and ...
