Why the study?
Does blood cardioplegia reduce postoperative conduction disturbances compared to crystalloid cardioplegia in patients undergoing coronary artery bypass grafting?

There was no difference in the incidence of postoperative conduction disturbances between blood and crystalloid cardioplegia during coronary bypass surgery.
Answers are grounded in this paper and cite their sources.
No preference for blood over crystalloid cardioplegia to avoid conduction disturbances after CABG; confirms equivalence in this RCT.
Postoperative conduction disturbances after coronary artery bypass grafting were analyzed in 100 patients who randomly received either blood or crystalloid cardioplegia. Conduction disturbances, mostly transient, developed after termination of cardiopulmonary bypass in 30 of the 100 patients--15 in either group. Ischaemia appeared to be a major determinant for conduction disturbances. Previous inferior myocardial infarction and stenosis of the right coronary artery both exposed the patient to risk of right bundle branch block.
