[Evaluation of disorders of the heart conduction system as risk factors in the surgical treatment of cholecystitis].

The author examined 1,144 patients with cholecystitis and found that 144 (12.6%) had heart block (HB)--atrioventricular block (AVB) and intraventricular block (IVB) were found in 11 and 133 patients, respectively. In some cases of cholecystitis, HB was combined with hypertensive disease, coronary heart disease, rheumatic heart disease. Patients with cholecystitis and HB underwent an exercise test (stepwise test) which was one of the principal criteria for the decision concerning the possibility of operating on the bile tract. A total of 864 (75.5%) patients with cholecystitis were operated on, 104 of whom had HB. No unfavourable outcomes were seen. Stable Stages I and III AVB (with an implanted cardiac pacemaker) and localized and complete block in the system of the right bundle branch without hemodynamic disorders were considered not to be a reason for rejecting surgery of cholecystitis. Surgery is inadvisable in block of some branches and complete (bilateral branch) block in the system of the left bundle branch, as well as in combination of Stage I AVB with IVB without performance of a graded physical exercise whose power should be at least 60% of the normal exercise, or 123 Wt, 750 kgm/min (the normal exercise being 100%, 176 Wt, and 1080 kgm/min).
