Treatment strategy of supraventricular tachycardia after coronary artery bypass graft / 中国医师进修杂志

ABSTRACT

Objective To summarize the treatment experience of supraventricular tachycardia (SVT) after coronary artery bypass graft (CABG). Methods The clinical data of 136 patients who had occurred SVT after CABG between January 2008 and December 2009 were analyzed retrospectively. Results Among 136 patients,no perioperative mortality,atrial fibrillation (AF) occurred in 110 cases (80.88%),paroxysmal supraventricular tachycardia (PSVT) occurred in18 cases ( 13.24% ), atrial flutter occurred in 8 cases (5.88%),112 of 136 cases occurred in 1-3 days after surgery,accounting for 82.35% ,24 cases occurred in 4-7 days after surgery,accounting for 17.65%. Given amiodarone in the treatment of 105 cases,100 cases reverted to sinus rhythm (cardioversion rate of 95.24% ),given esmolol in the treatment of 11 cases, 9 cases reverted to sinus rhythm( cardioversion rate of 81.82% ), synchronous direct current cardioversion in 20 cases, all transferred to sinus rhythm, all patients with improved symptoms. The remaining failed to transfer to sinus rhythm, had got normal ventricular rate, and symptoms improved significantly. Conclusions It is necessary to take effective measures to prevent SVT within 3 days after CABG. Amiodarone, esmolol and synchronous direct current cardioversion can be used effectively and safely to control SVT after CABG.
