Websmall Q waves correspond to depolarization of the interventricular septum. Q waves can … WebNotice that capital letters ( QRS) are used to designate waves of relatively large amplitude and small letters ( qrs) label relatively small waves. (However, no exact thresholds have been developed to say when an s wave qualifies as an S wave, for example.) The QRS naming system does seem confusing at first.

WebBackground: An abnormal Q wave is usually defined as an initial depression of the QRS complex having a duration of > or =40 ms and amplitude exceeding 25% of the following R wave in any contiguous leads on the 12-lead electrocardiogram (ECG). However, much smaller Q waves are sometimes recorded on the ECG. This study investigated the … WebRetrograde P-wave before or after the QRS, or no visible P-wave. The QRS complex is generally normal, unless there is concomitant intraventricular conduction disturbance. Figure 1 (below) displays two ECGs with junctional escape rhythm. Figure 1.

The following rules apply when naming the waves: 1. A deflection is only referred to as a waveif it passes the baseline. 2. If the first wave is negative then it is referred to as Q-wave. If the first wave is not negative, then the QRS complex does … See more The QRS complex can be classified as net positive or net negative, referring to its net direction.
