Depressed t wave ekg
WebMyocardial ischemia is a common cause of inverted T waves. Inverted T waves are less specific than ST segment depression for ischemia, and do not in and of themselves convey a poor... WebThe ECG machine processes the signals picked up from the skin by electrodes and produces a graphic representation of the electrical activity of the patient's heart. The basic pattern of the ECG is logical: electrical activity towards a lead causes an upward deflection. electrical activity away from a lead causes a downward deflection.
