Verapamil Wenckebach
Report:
Sinus rhythm
Möbitz 1 (Wenckebach) second degree AV block
Comment:
This is a very low-grade block and the patient is monitored anyway. Nothing needs be done immediately. In the long term, an antihypertensive without AV blocking properties should be chosen. Itâs the soil and the seed principle: most patients would not have any discernible AV conduction deficit from verapamil, but this one did.
As usual with long Wenckebach sequences, the ones recorded here are atypical. The distal chamber fails to accelerate before the pause.
