Atrial function in man.

Ventriculo-atrial conduction in man.

Transvenous electrodes were placed in the right atrium and ventricle of 50 patients with heart disease and arrhythmias. The ventricles were paced at several rates, each in excess of the sino-atrial rate. An atrial electrogram and surface electrocardiogram were recorded simultaneously in each patient; utilizing strict criteria, the incidence with which 1:1 ventriculo-atrial conduction (VAC) coul...

Rapid Atrial Pacing in Man

The first ten cycles following cessation of atrial pacing were evaluated in 44 control subjects (mean age 52.9 ± 14.88 yr) and 39 patients (mean age 62.9 ± 15.41 yr) suspected of having sinus node dysfunction (SND). The maximal cycle length for each postpacing cycle following several pacing periods in each control subject was determined, and was normalized by dividing it by the subject's mean s...

Pathology of atrial fibrillation in man.

common precipitating factors. Atrial dilatation was common but the SA node and internodal tracts were within normal limits. In contrast patients with long-term atrial fibrillation showed combinations of nodal artery stenosis, muscle loss in the SA node or internodal tracts, and atrial dilatation. The pathological conditions found most commonly were chronic rheumatic valve disease, ischaemic hea...
