title: [Determination of the sinus node recovery time].
abstract: The interrelationship between the sinus node recovery time and the rate of atrial stimulation was investigated in clinical experiments. The sinus node recovery time measured with the aid of atrial stimulation according to the recovery of atrial activity after stimulation was completed did not mirror the genuine sinus node recovery time. An empiric formula is suggested, permitting the determination of the genuine sinus node recovery time on the basis of the initial rhythm rate and maximal value of the sinus node recovery time measured according to the atrial activity recovery.
