SAN FRANCISCO -- Better indicators of high-grade atrioventricular (AV) conduction system abnormalities following transcatheter aortic valve replacement (TAVR) could be gleaned from an intraprocedural ...

In the lower tracing (lead II), P1 is conducted. P2 is blocked; in other words, this patient's AV node cannot conduct at the R1P2 interval. P3 was going to be conducted. How do I know that? This ...

Some consider 2:1 AV block to be type II block, claiming that the PR interval doesn't lengthen. What they don't realize is that determining whether the PR interval lengthens requires at least 2 ...

Factors including male sex, baseline conduction disturbances and intraprocedural atrioventricular block were associated with increased risk for permanent pacemaker implantation in patients with severe ...

In patients with atrioventricular septal defect (AVSD), the occurrence of nonsurgical AV block has been reported. We have looked for an explanation in the development of the AV conduction system.

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 ...

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 ...

Although there have previously been no reported cases of an interaction between trazodone and omeprazole, a new report is believed to be the first instance of reversible second-degree Mobitz type 1 ...

SAN FRANCISCO, CA—Conduction abnormalities like complete heart block (CHB) and left bundle branch block (LBBB) remain common in today’s TAVI patients, with some facing pacemaker implantation or even ...
