6,11–14 A junctional or nodal rhythm occurs when the QRS rate is faster than the resting P wave or sinus rate which is slowed in athletes due to increased vagal tone (figure 4). The QRS rate for ...

Below is an ECG strip of a patient with VT. See the PP interval when in sinus rhythm then march out the P waves within the wide QRS complex to find the AV dissociation that is present, confirming ...

Studies investigating QRS-complex abnormalities in association ... Few specific supraventricular rhythm disturbances other than sinus tachycardia were documented in both experimental and ...

QRS duration greater than 120 milliseconds Absence of Q wave in leads I, V5 and V6 Monomorphic R wave in I, V5 and V6 ST and T wave displacement opposite to the major deflection of the QRS complex ...
