In patients undergoing transcatheter aortic valve replacement (TAVR), high‑grade atrioventricular blocks occurring during and after the procedure had distinct mechanisms and predictors. Both ...
2:1 atrioventricular block is a form of second-degree AV nodal block and occurs when every other P wave is not conducted through the AV node to get to the ventricles, and thus every other P wave is ...

Transplacental transfer of anti-Ro antibodies is a well-known cause of conduction defects and permanent atrioventricular block in newborns. 1 In adults, conduction disturbances related to these ...
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 ...
In second-degree atrioventricular nodal block — also known as 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 ...
Limited studies are available regarding the pathophysiological mechanism of acquired atrioventricular block (AVB). Matrix metalloproteinases (MMPs) and angiotensin-converting enzyme (ACE) have been ...
