Research data from separate studies show that using electrophysiology tools to avoid the inadvertent injury of unseeable conduction tissue has drastically reduced postoperative heart block—and ...

Atrial tachycardia with 2:1 block; when atrial tachycardia occurs with a 2:1 conduction block, digoxin toxicity should be considered.

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 ...

In family CSM2, three out of four siblings developed complete atrioventricular conduction block requiring a permanent pacemaker at 2, 9 and 10 years of age. Between 20-24 years of age, all three ...
