A first-degree AV node block occurs when conduction through the AV node is slowed, thus delaying the time it takes for the action potential to travel from the SA node, through the AV node, and to the ...

The diagnosis is atrial tachycardia with variable (2:1 and 3:1) atrioventricular (AV) block and intraventricular conduction delay. The rhythm is regular at a rate of 72 beats/min, although one longer ...

For ventricular resynchronization patients, there are no commonly agreed upon criteria to judge who is responder and who is not. Responders can be defined by several parameters, such as For example, ...

Patients with atrioventricular (AV) block who don’t have an indication for cardiac resynchronization therapy (CRT) do better when treated with conduction-system pacing versus right ventricular septal ...

In second-degree AV nodal block (a.k.a. Wenckebach block or Mobitz Type I AV block), varying failure of conduction through the AV node occurs such that some P waves may not be followed by a QRS ...

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 ...

keyboard The American College of Cardiology, the American Heart Association, and the Heart Rhythm Society have released a guideline on the evaluation and management of patients with bradycardia and ...
