1. A method for producing an impact on the cardiovascular system of a human characterized with a blood flow and a blood pressure pulse wave having predetermined blood pressure pulse parameters, said method comprising the steps of:
providing an electrocardiogram (ECG) with a current ORS-complex, including an R-wave; providing a periodical compression of the human's extremities within a proximal zone, located at a predetermined distance downstream from the human's heart, and within a distal zone located downstream from the human's heart further than the proximal zone; said compression is provided by means of a plurality of pressure impulses, characterized with predetermined impulse parameters, each said pressure impulse is characterized with a front of the impulse; and said pressure impulses are synchronized with said QRS-complex and according to said blood pressure pulse parameters; providing a registration of the blood flow performed at a point located downstream from the human's heart further than said distal zone; providing a correction of the impulse parameters on the basis of said registration of the blood flow;wherein:the periodical compression of each said extremity is performed separately within said distal zone and said proximal zone, and said pressure impulses are delivered to said distal zone and to said proximal zone with a delay relatively to each other; said delay is provided as follows:
the front of the pressure impulse within the proximal zone is delayed in relation to the R-wave of the current QRS complex so that the pressure impulse in the proximal zone starts at the time of passing the blood pressure pulse wave from the human's heart through said proximal zone; the front of the pressure impulse within the distal zone is delayed in relation to the front of the pressure impulse in the proximal zone for the time of passing the blood pressure pulse wave between said proximal zone and said distal zone;wherein the compression within the said proximal and distal zones is terminated simultaneously prior to the start of a next QRS complex following the current QRS complex; andwherein said registration of the blood flow is performed on the human's finger or toe;delays between R-waves of the current QRS-complex and the maximums of the blood pressure pulse waves in the absence and in the presence of said pressure impulses are determined;a difference Δt is calculated according to the expression of:
Δt=tb−tO, wherein:tb, tO are the delays between R-peaks and the maximum values of the blood pressure pulse wave in the presence or in the absence of said pressure impulses, respectively; andthe front of the pressure impulse t1 in the said proximal zone is corrected according with the following expression: T1 corr.=t1−Δt. |
