[The values and limitations of recovery time in sick sinus syndrome (author's transl)].
143 patients were examined for SNRT and thus divided: 1st group: 39 patients with indisputable clinical signs of MNS (bradycardia-tachycardia, synocopes); 2nd group: 18 patients with constant sinusal bradycardia, but without arrhythmias; 3rd group: 86 patients without any clinical signs of sisusal automatism deficit. The average SNRT results were: 2346 plus or minus 1404 msec in the 1st group; 1337 plus or minus 181 msec in the 2nd group and 1021 plus or minus 216  msec in the 3rd. Corrected SNRT gave an average result of 1315 plus or minus 1300 msec in the 1st group; 329 plus or minus 229 msec in the 2nd and 234 plus or minus 133msec in the 3rd group. The values between the average and standard deviation...
