    • Reconfirmation of the position of a catheter intravascularly placed with the assistance of ECG signals of the patient is disclosed, thus assisting in determination of subsequent catheter displacement within the patient vasculature. In one embodiment a method for reconfirming a position of an indwelling medical device within a body of a patient comprises first placing the medical device within the body of the patient using ECG signals of the patient. A first ECG signal profile relating to an initial position of the indwelling medical device after initial placement of the medical device is stored. A second ECG signal profile relating to the position of the indwelling medical device at a time subsequent to initial placement of the medical device is then acquired. The first ECG signal profile is compared with the second ECG signal profile to determine whether displacement of the indwelling medical device has occurred.
    • 公开了借助于患者的ECG信号的血管内放置的导管的位置的再确认,从而有助于确定患者脉管系统中随后的导管置换。 在一个实施例中,用于重新确认患者体内的留置医疗装置的位置的方法包括首先使用患者的ECG信号将医疗装置放置在患者体内。 存储与初始放置医疗装置之后的居留医疗装置的初始位置相关的第一ECG信号轮廓。 然后获取与医疗设备的初始放置之后的时间相关的与居留医疗设备的位置相关的第二ECG信号轮廓。 将第一ECG信号轮廓与第二ECG信号轮廓进行比较,以确定是否发生了留置医疗装置的位移。
