The phrase paroxysmal supraventricular tachycardia describes a group of arrhythmias with
similar electrocardiographic features but different mechanisms that have been clarified in …

The mechanism of the electrocardiographic pattern termed left atrial enlargement was
evaluated in 21 patients. Left atrial size and pressure as well as interatrial conduction were …

To characterize the sequence of retrograde atrial activation in the presence of dual

In a proportion of patients with left free wall accessory connections, preexcitation is apparent
only during atrial arrhythmias or atrial pacing (latent preexcitation). These patients may be at …

Thirty-three patients with Wolff-Parkinson-White syndrome were studied
electrophysiologically before and after administration of intravenous procainamide and oral …
