METHOD OF SYNCHRONOUS REGISTRATION OF RHEOGRAM FROM ECG ELECTRODES AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC A61B5/432 

FIELD: medicine.

SUBSTANCE: electrodes of electric ECG potential registration are placed in zone of aorta and in zone of cardiac apex. Changes of electric potential on body in time are registered in form of diagram of ECG function. Near each electrode of ECG electric potential registration additional electrode is installed, onto which high-frequency signal from generator is supplied, and from electrodes of ECG electric potential registration modulated by fluctuations of arterial blood flow signal is obtained synchronously, said signal is amplified, converted into digital code and transmitted for rheogram registration to information processing unit, after which connection of ECG electric potential with change of pressure according to rheogram is connected in each phase, and phase peculiarities of arterial pressure change are diagnosed. Device for synchronous registration of rheogram from ECG electrodes consists of two ECG electrodes, commutator, first amplifier, first band filter, analogue-digital converter, controller, IR transmitter and information processing unit with first detector, commutator being inserted between electrodes and first amplifier, whose outlet through band filter is connected with first inlet of analogue-digital converter, whose outlet is joined to controller, whose first outlet is connected with commutator, and second outlet - with IR transmitter, connected with first detector of information processing unit. Two additional electrodes, second amplifier, second band filter, second detector and generator, switched to additional electrodes, are introduced into it, second commutator outlet is connected to inlet of second detector, whose output through second amplifier and second band filter is connected with second inlet of analogue-digital converter.

EFFECT: synchronous registration of phase characteristics of cardiac cycle and corresponding fluctuations of arterial pressure in heart vessels and aorta.
