[On the method for determination of sinus node recovery time (author's transl)].
On the basis of personal experience of 22 patients, 11 with sick sinus node syndrome (SSNS) and 11 without, it was concluded that the seat and length of atrial stimulation has little importance for the determination of recovery time for corrected sinus node (RTCSN). The frequency of optimal stimulation seems to be 110 impulses per minute for 2 minutes, by which it generally reaches the maximum value of RTCSN. Using this method, the falsely normal RTCSN in SSNS subjects can be verified; in these cases the test should be repeated within a larger frequency scope.
