METHOD AND DEVICE FOR COUNTERPULSATION THERAPY

摘要

A method of counterpulsation therapy is provided, the method comprising use of a combination of cardiac electrical activity and acoustic signals in such a manner that initially R wave on a cardiogram and then II (aortic) sound are determined, and, after the II sound has been determined, stimulation of muscles by means of electric impulses is initiated. A device for performing the above described method comprises a sensor of the signal of cardiac electrical activity and a sensor of cardiac acoustic signal; a unit for blocking the cardiac electrical activity signal; a unit for blocking the acoustic signal; and a control device coupled with muscle stimulating devices.

1. A method of counterpulsation therapy comprising the steps of monitoring the signals of cardiac electrical and acoustic activities; determining the moment of beginning the diastole phase of the cardiac cycle; and stimulating muscles, wherein in order to accurately determine the moment of beginning the diastole phase of the cardiac cycle in a cardiogram, the moment of beginning the R wave is determined at the time of blocking the signal of the cardiac acoustic activity; then the beginning of II (aortic) sound is determined in a phonocardiogram at the time of unblocking the signal of the cardiac acoustic activity, and, simultaneously, at the time of blocking the signal of the cardiac electrical activity; and, in the beginning of II (aortic) sound, feeding packets of electrical impulses is initiated, each packet having the duration of 7-15% of R-R interval.
