随着科技进步,心脏起搏器的安全度大大提高。与早期的起搏器不同,现在的起搏器被安装在金属盒内,以对抗外源性干扰;还通过双极导线将电流穿行距离缩短,从而使内源性肌肉活动所产生的干扰也得以控制。另外,一个特制的干扰讯号防护装置能在遇到干扰的情况下将起搏器转换到某一固定频率来维持其正常工作而免受病人内在心率的影响。本文作者指出,尽管如此,仍有许多潜在的危险因素。医护人员应向病人做好家庭康复指导。安装心脏起搏器的病人在家中可以安全地开关电灯、电视、收音机,也可睡电热毯;电动手钻、
As technology advances, the safety of pacemakers is greatly enhanced. Unlike earlier pacemakers, pacemakers are now installed in metal boxes to combat exogenous disturbances; they also shorten the current travel distance through bipolar leads, so that interference with endogenous muscle activity also results Controlled. In addition, a special interference signal protection device in the event of interference with the pacemaker will be converted to a fixed frequency to maintain its normal operation from the patient’s heart rate. The authors point out that in spite of this, there are still many potential risk factors. Health care workers should be good for family rehabilitation guidance. Patients with pacemakers can safely switch lights, TVs, radios or sleep blankets at home; electric hand drills,
