The effect of digoxin on sinus nodal reentry was examined in 20 open chest mongrel dogs during infusion of digoxin at a rate of 2.5 μg/kg per min. The extrinsic cardiac nerve supply was removed acutely in 10 dogs and was left intact in the remaining

Sinus node re-entry (SNR) usually appears as a single beat. Tachycardias (SNRT) consistent with sustained SNR were seen in six patients and were initiated by premature stimulation of the high right atrium (six patients) and coronary sinus (four patie

The recently developed experimental model for sinus nodal reentry was used to assess the effect of quinidine in 20 dogs. Sinus nodal reentry was demonstrated in 19 dogs and was abolished in all dogs when plasma levels of quinidine (average 4.8 mg/lit

Sinus and atrioventricular (A-V) nodal reentry are shown to coexist in the same patient, and the following conclusions are drawn: (1) Reentry at one nodal site may mask reentry at the other nodal site, (2) concealed reentry at either site may become

I t has been observed that during atrioventricular (A-V) dissociation the independence between atria and ventricles may not be as complete as the term implies. 1-4 Thinking in this area has been stimulated by the fascinating work of Segers6 demonstra

The effect of an early atrial premature depolarization (APD) on spontaneous atrial rate was assessed in 16 patients in sinus rhythm. At close coupling intervals (range 27 to 48 per cent of the preceding sinus cycle), atrial acceleration was observed

Digoxin was acutely administered to 17 patients, and its effects on atrioventricular (A-V) conduction were assessed. In the control state, before administration of digoxin, progressively premature atrial depolarization showed conduction delay and blo

A comparative analysis of the post-drive recovery patterns of the sinus node following equal numbers of sinus captures from right atrial and right ventricular drive was investigated in 15 dogs. Despite similar numbers of sinus captures, the post-driv
