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 ...

Please provide your email address to receive an email when new articles are posted on . Left bundle branch pacing was achieved for the first time via leadless pacemaker. Implantation failure rate was ...

Yogesh N. Reddy, MBBS: Hi. This is Yogesh Reddy, cardiology fellow at Mayo Clinic. Today we will be discussing the very common clinical scenario of a left bundle branch block (LBBB) on ...

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 ...

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

Physiologic pacing of the His-Purkinje conduction system is feasible in patients who require a permanent pacemaker following TAVR and this alternative pacing method did not interfere with ejection ...

Multicenter randomized trial (n=200) assigned LBBP versus BiVP for CRT in LBBB with LVEF ≤35%, using time to death or HF hospitalization as primary endpoint. Event rates favored LBBP, reducing death ...

Almost one-third of patients undergoing transcatheter aortic valve replacement (TAVR) with a balloon-expandable device develop new-onset left bundle branch block, although the condition resolves by ...

A person with RBBB typically does not have symptoms and may not know they have the condition. On rare occasions, a person may faint due to a severe block, though this is unlikely to occur unless other ...

ECG aberrancy means the heartbeat does not follow the usual conduction system of the heart. Atrial fibrillation with ECG aberrancy means people have an irregular heart rhythm with abnormal conduction.

In order for your heart to beat properly, your heart’s tissue conducts electrical impulses throughout your heart muscle in a regular pattern. This electrical impulse causes the upper chambers (atria) ...
