[Routine diagnosis in patients with latent sinus node syndrome].
The establishment of latent disturbances of the sinus node function is with high security successful by the determination of the sinus node recovery time only after medicamentous provocation with propranolol/atropin and verapamil, since the sensitivity of the determination of the sinus node recovery time is to small in the up to now usual way and in normal findings it is not able to exclude a sinus node dysfunction. The course of the investigation could be optimized according to the fact that despite complete medicamentous provocation only one running through stimulation is necessary without an endangering of the patient being the results. By this means of 75 patients 32 patients (43%) could be identified as sinus node syndrome of different degree of severity. On the basis of the improved ability of statement the determination of the sinus node recovery time for the diagnostics in patients with unclear syncopes and inconspicuous findings of the ECG should be performed only after a combined medicamentous provocation.
