Conventional electrocardiographic monitoring techniques depend on human observation of an oscilloscopic display for detection of transient rhythm disturbances such as premature ventricular contractions (PVCs). It is not surprising that such events are often missed. We have found that transient events are regularly identified only when they occur with a frequency exceeding one per minute. Rhythm disturbances such as coupled PVCs or PVCs in which R waves interrupt the preceding T wave ("R on T"), which constitute indications for antiarrhythmic therapy, may go undetected if they occur less frequently than this.
传统的心电图监测技术依赖于人工观察示波器显示屏，以检测诸如室性早搏（PVC）等短暂性心律失常。此类事件经常被漏诊也就不足为奇了。我们发现，只有当短暂性事件的发生频率超过每分钟一次时，才能被定期识别出来。诸如成对室性早搏或R波中断前一个T波（“R波落在T波上”）的室性早搏等心律失常，若其发生频率低于此，可能就无法被检测到，而这些心律失常是抗心律失常治疗的指征。
