What is a normal ECG reading?

WebThe ECG is recorded at a speed of 25 mm/sec (5 large squares/sec), and the voltages are calibrated so that 1 mV = 10 mm (2 large squares) in the vertical axis. Therefore, each small 1-mm square represents 0.04 sec … WebMaximal positive ECG deflection occurs in lead I when a wave of depolarization travels parallel to the axis from the right to left arm. If a wave of depolarization heads away from the left arm, the deflection is negative. Also, by these rules, a wave of repolarization moving away from the left arm is recorded as a positive deflection. Similar ... picking up the torchECG interpretationrequires firm knowledge of the characteristics of the normal ECG.
