Abstract
Experiments were carried out with anesthetized rabbits to attempt to clarify the relationship between the ballistocardiogram (BCG) and microvibration (MV).
Pilocarpine enhanced MV and inhibited BCG.
Succinylcholine markedly inhibited MV.
The body surface of the animals showed a vibration similar to MV after the cessation of the heart beat.
MV response differed from that of BCG, but the latter had an influence on the former.
It is suggested that MV consists of a neuromuscular vibrating element and a cardiac one.
