We examine the effects of fixed rate shock wave administration on the cardiac rhythm and treatment efficacy of a tubless lithotriptor (Dornier MFL 5000*). A secondary goal was to examine the treatment efficacy of fixed shock wave administration compared to R wave triggered lithotripsy.
In this prospective study Holter monitoring was used before, during and after nonR wave triggered shock wave lithotripsy.
An increase in premature ventricular contractions was noted during shock wave lithotripsy. However, there were no episodes of significant ventricular ectopia, ventricular tachycardia, asystole or heart block as a result of nonR wave triggered shock wave administration. NonR wave gated shock wave lithotripsy expedited patient treatment and (mean treatment time 46 +/- 21 minutes)., minimized the use of sedation during treatment and produced results similar to R wave gated shock wave lithotripsy with the MFL 5000 lithotriptor.
With adequate precautions, fixed rate shock wave administration would appear to be a reasonable option to treat urolithiasis with the MFL 5000 lithotriptor as with other newer lithotriptors.
我们研究了固定频率冲击波治疗对心律的影响以及无管碎石机（多尼尔MFL 5000*）的治疗效果。第二个目标是比较固定频率冲击波治疗与R波触发碎石术的治疗效果。
在这项前瞻性研究中，在非R波触发的冲击波碎石术前、术中及术后使用动态心电图监测。
在冲击波碎石术期间观察到室性早搏增加。然而，非R波触发的冲击波治疗未导致显著的室性异位、室性心动过速、心搏停止或心脏传导阻滞发作。非R波门控冲击波碎石术加快了患者的治疗进程（平均治疗时间46±21分钟），减少了治疗期间镇静剂的使用，并且使用MFL 5000碎石机产生的结果与R波门控冲击波碎石术相似。
采取适当的预防措施后，对于使用MFL 5000碎石机及其他新型碎石机治疗尿路结石而言，固定频率冲击波治疗似乎是一种合理的选择。
