1:1 Conduction of Atrial Flutter. When a class IC antiarrhythmic drug is used for atrial flutter, an AV blocking agent must be used simultaneously to avoid a paradoxical increase in ventricular rates.

Atrial flutter with 2:1 conduction block can easily be mistaken for sinus tachycardia or atrial tachycardia because a flutter wave is often buried in the T wave; however, a rate of 150 beats per ...

Another fully digitalized patient, in whom atrial flutter with 2:1 block developed after mitral commissurotomy, had a rapid ventricular rate that was refractory to the administration of ...

Atrial flutter occurs when a “ reentrant ” circuit is present, causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute; the ...
