Abstract

In each cycle of the electrocardiogram wave there are P, Q, R, S and T amplitudes. Many studies have been conducted to obtain amplitude and QRS waves because they are related to ventricular depolarization, but to obtain T amplitude values related to ventricular repolarization are still rarely done, not even for the clinical standard (12 leads). This study aims to obtain the amplitude T value in each cycle and each electrocardiogram lead. Obtaining the amplitude T position on the reference lead will also find the amplitude T value on the other lead. Each cycle duration obtained from the duration RN to RN+1 is used to obtain the position of the endpoint of each cycle. The maximum value between the amplitude S position and the end point of the cycle is the amplitude T value. The results of research on 10 Physionet sinus rhythm samples and 10 Saiful Anwar Hospital Malang samples show that the duration of the cycle was successful in obtaining the amplitude T value for each lead. All samples can display a value. The amplitude in each cycle, where the values obtained in each cycle are still in normal conditions. The amplitude T value obtained is certainly accurate because there is only one positive value between the amplitude S position and the end of the cycle position. The position of the amplitude integer T found in a cycle in one lead will be the same as the position of the amplitude integer T in the cycle for the other lead. This occurs because of the simultaneous transmission of impulses that affect the atrial and ventricular muscle cells. The position of the amplitude T for each cycle can be found by filtering the maximum amplitude value between the amplitude position S and the final position of the cycle. Practically, this method can be programmed to be added to a digital electrocardiograph
