NCIt definition : An electrocardiographic finding of a regular supraventricular tachycardia due to reentry
within the AV node. It is characterized by P waves which typically occur nearly simultaneously
with the QRS complex, resulting in a P wave which is obscured by the QRS, merged with
the QRS or which may follow the QRS. (CDISC);
