The implantable loop recorder is a useful diagnostic tool for patients with unexplained syncope. The capability to automatically detect and store arrhythmic events, implemented in the last generations of these devices, can further improve the diagnostic yield, but this feature can be compromised by inappropriate detection of false arrhythmias. We herein report the case of a patient in which several inappropriate activations of long-lasting asystole occurred in the two days following the implant, probably because of an intermittently loose contact between the device and subcutaneous tissue for a small pocket haematoma.
植入式循环记录仪是不明原因晕厥患者的一种有用诊断工具。在这些设备的最新一代产品中实现的自动检测和存储心律失常事件的功能,可以进一步提高诊断率,但这一功能可能会因错误心律失常的不适当检测而受到影响。我们在此报告一例患者,在植入后的两天内发生了几次持续时间较长的心脏停搏的不适当激活,可能是由于小口袋血肿导致设备与皮下组织之间间歇性松动接触所致。
