Abstract

Paper describes new method minimizing ECG records interference during non-invasive transcutaneous cardiac stimulation allowing wider use of this method for diagnosis of myocardial ischemia. By moving the electrodes of ECG precordial leads to lower intercostal spaces it was achieved the smaller penetration of pulse from front surface stimulating electrode. Eliminating the possibility of input circuit overload by interference has improved the effects of applied solutions of stimulating pulses suppression during the test. Waveforms of shifted leads are shown in the records after conversion of successive samples to a value corresponding to standard position on the basis of coefficients being determined for each patient at the test beginning. Achieved have been better records in all patients and in some patients eliminated was the problem of collision occurrence between standard location of precordial leads and optimal location of the front stimulating electrode thus impeding or preventing execution of the test.
