Abstract

The purpose of this study was to assess the effects of five electronic apex locators on pacemaker function in vitro. A Biotronik Actros DR+ pacemaker was evaluated at maximum sensitivity on a flat bench top. The pacemaker lead, electronic apex locator, and oscilloscope were connected across a 150-ohm resistor. Pace monitoring was carried out with a Biotronik EPR 1000 programmer and a Tektronix TDS 220 2-channel digital real-time oscilloscope. Four of five electronic apex locators tested did not cause inhibition or interfere with normal pacemaker function. It seems that electronic apex locators can be used safely in patients with pacemakers.

摘要

本研究的目的是评估五种电子根尖定位仪对体外起搏器功能的影响。在一个平坦的实验台上，以最大灵敏度对百多力Actros DR+起搏器进行了评估。起搏器导线、电子根尖定位仪和示波器通过一个150欧姆的电阻连接。使用百多力EPR 1000编程器和泰克TDS 220双通道数字实时示波器进行起搏监测。所测试的五种电子根尖定位仪中有四种不会引起抑制或干扰起搏器的正常功能。看来电子根尖定位仪可在有起搏器的患者中安全使用。
