In the present case, without any arrhythmias or perfusion defects, severe abnormalities of wall contraction and thickening were demonstrated because of prominent T waves. This gating error was easily corrected by changing guidance lead to increase the amplitude of the R wave and decrease that of ...

due of the lack of precision in determining the exact end of the T wave and when U waves, which tend to merge with the end of the T wave, are present. Additionally, U waves may represent some abnormalities, such ashypokalemia, even though they may also be present in the ECG under nor...

aIt is therefore advantageous to use a simple mathematical analysis of the ECG signal. Regarding memory, representation of the complete ECG signal by an equivalent diagnostic word appreciably reduces the memory size required. Figure 1 shows the P, Q, R, S and T waves on an electrocardiogram tra...

This may result in an increase in "relatively high T waves". We found no studies or reports of similar distortion of the ECG waveform occurring with devices from other manufacturers. However, past reports have indicated that changes in the appearance of the ECG (waveform impairment) or possible...
