In patients with high-grade atrioventricular block (AVB), a standard dual-chamber pacemaker can restore A-V synchrony and ensure an adequate ventricular pacing rate. In this setting, however, the ...

Mobitz type I, also known as the Wenckebach block, is a subtype of second-degree atrioventricular (AV) block. Mobitz type I is a type of conduction disorder, which happens when the electrical signals ...

Please provide your email address to receive an email when new articles are posted on . The new leadless pacemaker (Micra AV, Medtronic) is indicated for the treatment of patients with ...

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 ...

There are three types of second degree heart block, also called atrioventricular (AV) block. In type I the signal sometimes does not reach the ventricles, causing skipped beats. It is often benign and ...

NEW YORK, NY—High-grade atrioventricular (AV) block occurs within 1 month for roughly one in seven patients who undergo transcatheter tricuspid valve replacement (TTVR), according to new results from ...

DENVER, CO—The use of an implantable loop recorder (Reveal LINQ, Medtronic) identifies a high incidence of arrhythmic events at 12 months in patients who develop persistent left bundle branch block ...

A 31-year-old woman with no significant medical history presents with intermittent heart palpitations, dizziness, shortness of breath, and fatigue provoked by exercise. Can you make the diagnosis? A ...

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 ...

Right ventricular pacing restores an adequate heart rate in patients with atrioventricular block, but high percentages of right ventricular apical pacing may promote left ventricular systolic ...
