SpletR-wave progression. R-wave progression is assessed in the chest (precordial) leads. Normal R-wave progression implies that the R-wave gradually increases in amplitude from V1 to … SpletFigure 1. Electrode positions on an ECG (EKG). When electrical activity (or depolarisation) travels towards a lead, the deflection is net positive. When the activity travels away from the lead the deflection is net negative. If it is at 90 degrees then the complex is ‘isoelectric’ i.e. the R and S wave are the same size. Splet29. mar. 2016 · The presence of an S-wave in leads I, II, and III was examined. The amplitude (mV) from the isoelectric line to the nadir of the S-wave and the duration (ms) from the beginning to the end of the S-wave in leads I, II, and III were measured with calipers.
