In contrast to testing of the capture threshold, the reliability of sensing tests has been little studied. This study was performed to test the automatic sensing algorithm included in the Biotronik pacing systems. The automatic measurements made by the devices were compared with the direct manual measurements made of 271 atrial (72%) or ventricular (28%) electrograms recorded in ten patients. A high correlation (r = 0.995, P < 0.0001) was found between the two types of measurements. The use of this function should facilitate the verification of accurate sensing during the long-term follow-up of pacemaker patients, and offers a tool to analyze the variations in amplitude of intracardiac signals.
与捕捉阈值测试不同，感知测试的可靠性研究较少。本研究旨在测试百多力起搏系统中包含的自动感知算法。将设备进行的自动测量结果与对10名患者记录的271份心房（72%）或心室（28%）电图进行的直接手动测量结果进行比较。发现两种测量类型之间具有高度相关性（r = 0.995，P < 0.0001）。该功能的使用应有助于在起搏器患者的长期随访中验证准确感知，并提供一种分析心内信号幅度变化的工具。
