Wearable cardioverter-defibrillators (WCDs) are a well-established tool to bridge the recovery time of left ventricular ejection fraction (LVEF) until the implantation of an implantable cardioverter defibrillator (ICD), as recommended by the current guidelines. Besides their function to detect and treat malignant arrhythmias, WCDs may be used as a telemonitoring system. In this study, we sought to illustrate and discuss the telemonitoring potential of WCDs and to analyze physical activity in specific patient cohorts.
We retrospectively included 140 patients with reduced LVEF who were prescribed WCDs in our clinic. We analyzed the patients' physical activity ( = 105 with a WCD compliance above 21 h/day), body position and resting position. We found a reduced physical activity in women and in patients over the age of 65 compared to younger patients. Furthermore, the patients who were overweight or obese showed significantly reduced physical activity compared to the patients with a normal weight (6365 ± 3572 vs. 4972 ± 2476 vs. 7045 ± 3521, = 0.02).
WCDs may be used as a telemonitoring and intervention tool in patients with reduced LVEF. Specific patient groups may benefit from guidance from their treating physician regarding physical activity.
按照现行指南推荐，可穿戴式心脏复律除颤器（WCD）是一种成熟的工具，用于在植入植入式心脏复律除颤器（ICD）之前的左心室射血分数（LVEF）恢复期间发挥桥梁作用。除了检测和治疗恶性心律失常的功能外，WCD还可作为远程监测系统使用。在本研究中，我们试图阐述和讨论WCD的远程监测潜力，并分析特定患者群体的身体活动情况。
我们回顾性纳入了140例在我们诊所被处方使用WCD的LVEF降低的患者。我们分析了患者的身体活动（n = 105，WCD依从性高于每天21小时）、体位和静息位。我们发现，与年轻患者相比，女性和65岁以上患者的身体活动减少。此外，超重或肥胖患者的身体活动与体重正常的患者相比显著减少（6365±3572 vs. 4972±2476 vs. 7045±3521，P = 0.02）。
WCD可作为LVEF降低患者的远程监测和干预工具。特定患者群体可能受益于治疗医师给予的关于身体活动的指导。
