Answers are grounded in this paper and cite their sources.
Removal of a diseased gallbladder may decrease arrhythmia potential in patients with associated coronary heart disease but does not alter the angina threshold.
Fifty patients subjected to operation for gallbladder disease undertook cardiac stress tests before and two months after surgery. Fourteen showed evidence of preexisting coronary heart disease and this was unaltered by operation. Squeezing the gallbladder during surgery provoked arrhythmias in six out of 10 patients with coronary heart disease and in two out of 14 of those without demonstrable heart disease. Removal of a diseased gallbladder may decrease the arrhythmia potential, particularly In patients with associated coronary heart disease, but does not alter the angina threshold.
