The examination has involved 47 patients operated on for maxillofacial tumors. The patients' ages varied from 16 to 74 yrs. They were divided into 2 groups: Group 1 (n = 24) patients were only surgically treated; Group 2 (n = 23) ones were operated on after a course of radiotherapy; ECGs were recorded routinely. ECG changes, not observed before, were detected in the first days after surgery; these were the changes mainly in the repolarization phase. The most manifest were myocardial injury, ischemia, augmentation of electrolytic and hypoxic disorders, myocardial dystrophy. Arrhythmias and blockages of various types developed. These disorders persisted for up to 1-2 weeks and their time course was positive. In the patients operated on after radiotherapy the ECG changes were augmented by the shifts resultant from radiotherapy effects on the myocardium. These data necessitate ECG monitoring of this patient population after surgery, which helps timely detect and treat acute injuries of the myocardium.
该检查涉及47例接受颌面肿瘤手术的患者。患者年龄在16岁至74岁之间。他们被分为两组：第1组（n = 24）患者仅接受手术治疗；第2组（n = 23）患者在进行一个疗程的放射治疗后接受手术；常规记录心电图。术后头几天检测到术前未观察到的心电图变化；这些变化主要发生在复极阶段。最明显的是心肌损伤、缺血、电解和缺氧紊乱加重、心肌营养不良。出现了各种类型的心律失常和传导阻滞。这些紊乱持续长达1至2周，其病程呈阳性。在接受放射治疗后进行手术的患者中，放射治疗对心肌的影响所导致的变化使心电图改变更加明显。这些数据表明有必要对该患者群体术后进行心电图监测，这有助于及时发现和治疗心肌急性损伤。
