摘要：

A comparison was made of the effects of ventricular pacing and sequential A-V pacing at individually determined optimal P-R intervals in ten patients with A-V block. At heart rates 10 beats per minute faster than sinus rate, the average cardiac output increased from 4.6 to 5.7 L. per minute (24 per cent, p < 0.001) and central venous pressure fell from 5.5 to 2.5 mm. Hg (p < 0.01), with the restoration of properly timed atrial systole. The results were similar in six of the patients studied at a rate of 40 beats per minute faster than sinus rate. © 1969.
