  • Title: Supraventricular tachyarrhythmias after coronary bypass surgery--a double blind randomized trial of prophylactic low dose propranolol.
    Author: Martinussen HJ, Lolk A, Szczepanski C, Alstrup P.
    Journal: Thorac Cardiovasc Surg; 1988 Aug; 36(4):206-7. PubMed ID: 2903581.
    Abstract:
    In the present study 75 patients were double blind randomized either to receive 10 mg propranolol orally 4 times a day (35 patients) or a placebo (40 patients). Episodes of clinically important supraventricular tachyarrhythmias were recorded in the first 4 postoperative days. They appeared in 5 of 35 patients receiving propranolol and in 5 of 40 patients receiving placebo (no statistically significant difference). In conclusion this study indicates the need for further evaluation to clarify if low-dose propranolol or any other drug is effective in reducing the frequency of SVT in the early postoperative period after coronary artery bypass surgery.
