Abstract

Describes a computer-based system for simultaneously recording the amplitude of precordial vibrations (PCG) from 22 sites on the chest. This system is the first prototype of a cardiac acoustic mapping system designed to acquire, analyze, and display the amplitude maps of the PCG in real-time. Preliminary results show that thoracic mapping of the PCG can provide a means of locating the source of cardiac sounds and murmurs on the chest and to characterize their radiation and propagation patterns
