WebPulsed-wave mapping demonstrated that peak velocity of the end-diastolic left ventricular outflow tract signal (J wave) was maximal, 2.6 +/- 0.7 cm from the aortic valve anulus, and occurred 48 +/- 34 milliseconds after the peak transmitral atrial velocity flow signal. Peak J velocity ranged from 25 to 118 cm per second and correlated with peak ... WebFeb 11, 2016 · Amplitudes are relative peak-to-peak measures. If you are asking about absolute values then the minimal voltage versus maximal absolute voltages depend on your baseline value, i.e., the offset in your voltage potential measurement system. Further, artifacts and background noise may add signal amplitudes on top of the ECG proper.
