WebECG interpretation starts with assessment of the P-wave and PR interval. The P-wave is generated by depolarization (activation, contraction) of the atria. The PR interval is the interval between the start of the P-wave and the start of the QRS complex. The PR interval determines whether impulse transmission from atria to ventricles is normal. WebApr 20, 2024 · Vertically, the ECG graph measures the height (amplitude) of a given wave or deflection. The standard calibration is 10 mm (10 small boxes), equal to 1 mV. On occasion, particularly when the waveforms are small, double standard is used (20 mm equals 1 mv). When the wave forms are very large, half standard may be used (5 mm equals 1 mv).
