Studying cardiac contractility change trend to evaluate cardiac reserve.

There is a very close relationship between the amplitude of the first heart sound and the cardiac contractility. We previously presented the concept of cardiac contractility variability (CCV) and an analysis method. On the basis of the findings from the authors' observation and other previous s...
