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.

WebMay 16, 2024 · Most literature defines ER as being present on the ECG when there is J-point elevation of ≥0.1 mV in two adjacent leads with either a slurred or notched morphology. Historically, ER has been considered a marker of good health because it is more prevalent in athletes, younger persons, and at slower heart rates. WebThe different waves that comprise the ECG represent the sequence of depolarization and repolarization of the atria and ventricles. The 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.
