ABSTRACT
Sequenital mechanical pulsing of the chest wall with three stimuli failed to induce arrhythmias in normal dogs. After coronary arterial occlusion, this technique evoked in 11 of 12 animals repetitive ventricular tachycardia in 2. These responses corresponded closely to those elicited by electrical testing. In four conscious animals after recovery from myocardial infarction, precordial pulsing induced repetitive ventricular arrhythmias. The type of arrhythmia produced depended on the degree of prematurity of the third pulse in the sequence. The use of precordial mechanical stimulation can perhaps be modified and adapted as a method of detecting persons at high risk for sudden cardiac death.
