During a 1-year period 37 patients who underwent treatment with a noninvasive temporary pacemaker were followed to evaluate effectiveness and outcome of therapy. The device was most frequently used in the emergency department and coronary care unit and was applied by a nurse in 51% of cases. Pacing thresholds ranged from 20 to 110 mA (mean 43 mA) with 91% obtaining capture. Pacing was continuous in 11 patients for 5 to 180 minutes (mean 32 minutes) and intermittent in 16 patients for up to 72 hours. Pacing did not take place in 10 patients because of failure to capture or because a satisfactory intrinsic rate was maintained. After external pacing, six patients received permanent pacemakers, 14 required temporary transvenous pacemakers, 10 required no further pacing, and seven (19%) died. Few problems were encountered, although eight of the 20 responsive patients had severe discomfort related to pacing, with two of these requiring discontinuation of pacing. The number of temporary transvenous pacemaker insertions in the coronary care unit decreased 32% over a 6-month period after introduction of the noninvasive temporary pacemaker. We conclude that the noninvasive temporary pacemaker is safe and effective although discomfort may limit its use in some patients.
在为期1年的时间里,对37例接受无创临时起搏器治疗的患者进行了随访,以评估治疗的有效性和结果。该设备最常用于急诊科和冠心病监护病房,51%的病例由护士操作使用。起搏阈值为20至110毫安(平均43毫安),91%的患者实现夺获。11例患者持续起搏5至180分钟(平均32分钟),16例患者间歇起搏长达72小时。10例患者因未能夺获或维持满意的自身心率而未进行起搏。体外起搏后,6例患者接受了永久性起搏器,14例需要临时经静脉起搏器,10例无需进一步起搏,7例(19%)死亡。尽管20例有反应的患者中有8例因起搏出现严重不适,其中2例需要停止起搏,但遇到的问题很少。在引入无创临时起搏器后的6个月内,冠心病监护病房中临时经静脉起搏器的植入数量减少了32%。我们得出结论,无创临时起搏器是安全有效的,尽管不适可能会限制其在某些患者中的使用。
