A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. This term can be confusing, as not all ECG leads contain all three of these waves ...
6). The interpreter may be alerted to the artifact by the concomitant shortening of all ECG intervals (PR, QRS, QT, and RR) and decrease in QRS voltage. Conversely, transient slowing or sticking ...
The QRS complex consists of the Q wave, the R wave and the S wave. The QRS complex comes after the P wave when the SA nodal action potential travels through the AV node to the ventricles to cause ...
