I,ll have to ask for my money back from med school. I still say there are dissociated P waves at a tachy rate, through out most of the strip. The ventricles are probably being controlled at the junctional level, the initial part of the strip over 150, which should have been called a junctional tach and not an accellerated rhythm (my bad). I would have liked to see more of the rhythm strip to see if it stayed slow.
