目的 研究冠状动脉CT造影阴性的胆心综合征患者术后临床症状和心电图相关指标改变情况?方法 回顾性分析我院68例冠状动脉CT造影阴性的拟诊胆心综合征患者，观察所有患者(n=68)术前?术后胸闷?胸痛?心悸症状的发生率差异和心电学ST-T改变?窦性心动过缓?早搏的发生率差异?结果 患者术后胸痛或胸闷(5.88%vs.52.94%)?心悸(1.47%vs.13.23%)发生率较术前明显改善(P<0.05);患者术后心电图ST段改变发生率(2.94%vs.58.82%)?T波改变发生率(4.41%vs.32.35“,”Objective To explore the changes of preoperative and postoperative clinical symptoms and ECG related indexes in patients with biliary-cardiac syndrome with negative coronary CT angiography. Methods A retrospective analysis was performed on 68 patients with suspected biliary-cardiac syndrome with negative coronary CT angiography in our hospital.The incidence differences of chest tightness， chest pain，palpitation and the incidence differences of ECG ST-T changes， sinus bradycardia and premature beats before and after operation were observed in all patients (n=68). Results The incidence of postoperative chest pain or chest tightness (5.88% vs. 52.94%) and palpitation (1.47% vs. 13.23%) was significantly improved compared with those before operation (P <0.05); the incidence of ST segment changes (2.94% vs. 58.82%)， T wave changes (4.41% vs. 32.35%)， sinus bradycardia (2.94%vs. 26.47%) and premature beats (1.47% vs. 13.23%) in postoperative ECG were significantly improved compared with those before operation (P <0.05). Conclusion Biliary-cardiac syndrome can cause clinical manifestations and ECG changes similar to coronary heart disease， which can be significantly improved with the remission or cure of biliary system disease.
