WebMar 21, 2024 · There is progressive prolongation of the P-R interval following each atrial impulse, until an atrial impulse fails to be conducted to the ventricles. A ventricular impulse is 'dropped' and, following this, AV conduction recovers to its baseline optimal level and the cycle repeats itself. dyson v7 not working properly
