WebbThe QRS complex consists of three waves: Q, R and S. Differences in the direction of these waves are due to changes in the direction of the electrical impulse during ventricular depolarization. The T-wave … WebbThe following ECG criteria are commonly used to diagnose LBBB: QRS duration ≥0,12 seconds. Leads V1-V2: deep and broad S-wave. The small r-wave is missing or smaller than normal. If it is missing, a QS complex …

Then do the same for the S-wave. The arrival of seismic waves will be recognized by an increase in amplitude – look for a pattern change as lines get taller and more closely … dibby businessWebbIt is an R-wave, followed by an S-wave, followed by another R-wave. In other words, an upward deflection, followed by a downward deflection, followed by another upward deflection. Voila! That’s it.
