The first ECG strip below shows a P wave with sinus ... atrial flutter and multifocal atrial tachycardia. Note that when atrioventricular, or AV, dissociation is present (complete heart block ...

This ECG strip shows AV dissociation ... or slow ventricular tachycardia. The atrial rate is indicated by the P waves. There are almost exactly five large boxes between P waves, indicating ...

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 ...

[1] A large proportion of SND patients also have atrial fibrillation (AF) and prolonged sinus pauses after AF termination, which is also known as tachycardia-bradycardia syndrome. When ...
