Premature ventricular contraction response-induced new-onset atrial fibrillation

Ventricular response to atrial fibrillation.

The result of the management of the seven cases of cardiac tumors reported by Bini et al. (I) was quite discouraging as only one child survived 3 months. In a recent review of cardiac tumors reported in the English language between 1972 and 1977 (2), I found 47 reported pediatric cases with a survival rate of more than 6 months in 55% of the cases. Forty-four of these tumors were benign with a ...

Ventricular Response in Atrial Fibrillation

The data on durations of the intervals between successive R-R waves in the ECG from patients during atrial fibrillation, reported by Horan and Kistler (Circulation Research 9: 305, 1961) show that the larger the mean and modal value in a record the larger were the shortest and longest durations. The finding that the latter extreme was usually a few times larger than the former has been used in ...

Study of Ventricular Response in Atrial Fibrillation

PHYSICIANS have long reflected upon the irregularity of pulse in patients with atrial fibrillation. The peculiar ventricular response found in atrial fibrillation provokes such questions about the nature of conduction from atrium to ventricle as, for example: Is the ventricular rhythm absolutely irregular? If there is not a random distribution of the varying time interval between beats, does a ...
