[[File:E0007622.jpg|thumb|600px|left|This second EKG is interesting as again it shows a supraventricular tachycardia with group ventricular beating with clusters of regular rhythm at about 215/min. The regularity and group beating suggest that this is an organized rhythm and not atrial fibrillation. Look carefully at the interval between the 6th and 7th beats in lead II. Clearly atrial activity is seen at about 215/min.  
This is an interesting case where the diltiazem has slowed down the SVT which has allowed faster conduction down the A/V node and hence an increase in the ventricular rate.]]

This is a rhythm strip from a 54 year old patient who had had a surgical correction for Tetralogy of Fallot and who was taking Sotalol for palpitations. He was well with the exception of palpitations which could never be recorded with an EKG machine or a Holter monitor. The patient was given a continuous loop monitor for several weeks. This is a segment of a tracings recorded by the patient when he had his palpitations. An EKG taken with the patient on Corgard and Digoxin
