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; yet ...

Wandering atrial pacemaker (WAP) requires three different P wave morphologies in one ECG with a QRS complex rate of < 100. Idioventricular rhythms meet criteria for ventricular tachycardia, but ...

The three next most common supraventricular tachycardias — atrioventricular nodal ... P waves follow the QRS complex in atrioventricular nodal reentrant tachycardia and atrioventricular ...

QRS complex: This shows electrical activity running through the heart to the ventricles, which are the two lower chambers. T wave: This shows the electrical reset of the heart in preparation for ...

The interval between the P wave and each QRS complex is usually less than 0.2 seconds and should be consistent. The PR interval should be calculated and consistency assessed throughout the rhythm ...

An electrocardiogram shows a regular tachycardia with a narrow QRS complex and no apparent P waves. How should her case be managed? ... Most ablation procedures take one to three hours.

There are three main waves that make up this graph. These three waves are: ... It corresponds to the area visible at the end of the QRS complex and the beginning of the T wave.

Figure 2 shows a regular rhythm at a rate of 90 beats/min. The QRS complex duration is increased (0.14 sec), and there is a morphology of a right bundle branch block with an RSR' morphology in ...

Did you know that certain medications can cause symptom of 'QRS complex'. Find these drugs listed on the page and be warned of similar symptoms as possible side-effects.

The rhythm is regular at a rate of 100 beats/min. A P wave occurs before each QRS complex (+) with a stable but short PR interval (0.12 sec). The PR interval is shorter than what would be expected ...
