Summary
Between May 1980 and February 1985, 30 patients were operated upon at Sahlgren's Hospital
for life-threatening or drsabling arrhythmias, caused by Kent's bundles. Two surgical
methods were used. The outcome of surgery was fully satisfactory in 19 patients, whereas
4 patients continued to have arrhythmias after surgery. Six patients had a modified
deltawave in the ECG after surgery, but their arrhythmias could be controlled by antiarrhythmic
medication. One patient died after surgery due to an undiagnosed cerebral tumor.
There were 2 late deaths, between 6 and 12 months postoperatively; neither of these
was caused by arrhythmias.
