Abstract
Objective To investigate the ECG changes in pheochromocytoma.Methods 43 cases of pheochromocytoma patients preoperative ECG examination,patients with preoperative have high blood pressure can be divided into group A (13 cases),no high blood pressure in group B (30 cases),compare electrocardiogram change difference between two groups have statistical signifi-cance.Results Group A and group B preoperative ST-T change of 7 cases respectively,9 cases;A total of 16 cases of about 37.2%.Left ventricular surface of high voltage respectively 4 cases,1 case;A total of 5 cases of about 11.6%.Sinus arrhythmia in 1 case,respectively,1 case,a total of 2 cases,accounting for about 4.65%;Left anterior branch block respectively 0 cases,2 cases;Acceleration border sex rhythm of the heart in 1 case,respectively,0 cases;Right ventricular sur-face of high voltage respectively 0 cases,1 case;Room sex premature beat respectively 0 cases,1 cases;Ventricular premature beat,respectively 0 cases,1 cases;Early bipolar respectively 0 cases, 1 cases.Conclusion group A and group B preoperative ecg ST-T change,the difference between the two groups has no statistical significance,preoperative electrocardiogram (ecg)changes in ST-T in the majority,A total of 16 cases accounted for about 37.2%,consider possible for pheochromocyto- <br> ma hypersecretion catecholamine caused by myocardial injury.Group A and group B increased pre-operative electrocardiographic left ventricular surface voltage,the difference between the two groups was statistically significant,considering possible reasons for A group of sustained high blood pres-sure,so compared with group B were more likely to overload caused by sustained hypertension left ventricular contraction caused in addition to the electric power increase,Characterized by increased left ventricular surface voltage.Preoperative ecg sinus arrhythmia group A and group B,the differ-ence between the two groups have no statistical significance,sinus arrhythmia group A and group B are all young people is normal physiology reaction.关键词
