Atrioventricular Nodal Reentrant Tachycardia (AVNRT) is a type of SVT and is the commonest cause of palpitations in patients with hearts exhibiting no structurally abnormality.
Defined as PR interval > 200ms, commonly caused by AV nodal blocking drugs
RPWT is the time from onset of earliest Q wave or R wave to the peak of the R wave in lateral leads
