This is a narrow-complex QRS rhythm which is quite fast. Looking closely at the last part of the QRS complex in leads V1 and V2, P waves can be seen. This is considered a "short RP tachycardia" and is ...
Note the premature ventricular contraction (PVC) that triggers the AVNRT in this ECG. If a premature atrial contraction (PAC) or premature ventricular contraction (PVC) occurs at the right time, the ...
The rhythm is regular at a rate of 150 beats/min; however, there are two long RR intervals (↔). The QRS complex is narrow (0.08 sec) and has a normal morphology and normal axis between 0° and 90° ...
