The QRS complex can be wide if aberrancy is present (ie, right or left bundle branch blocks). Causes of atrial tachycardia include chronic hypertension, congestive heart failure, valvular heart ...

Atrial Tachycardia with 2:1 Block. When atrial tachycardia occurs with a 2:1 conduction block, digoxin toxicity should be considered.

Other rhythm disturbances, especially atrial tachycardia originating close to the sinus node and right upper pulmonary vein tachycardia, can also hinder differential diagnosis. The distinction ...

Background: Only a few algorithms for predicting the site of origin of focal atrial tachycardia (AT) have been reported. We aimed to develop a new and more effective algorithm. Methods ...

sinoatrial block, and alternating episodes of tachycardia and bradycardia. [1] A large proportion of SND patients also have atrial fibrillation (AF) and prolonged sinus pauses after AF termination ...
