Abstract

BACKGROUND

Participation in phase-III cardiac rehabilitation (CR) remains low but adherence could potentially be improved with supervised home-based CR. New technological approaches are needed to provide sufficient supervision with respect to safety and performance of individual exercise programmes.

DESIGN

The newly designed closed-loop tool, HeartCycle's guided exercise (GEX) system, will support professionals and patients during exercise-based CR. Patients wear a dedicated shirt with incorporated wireless sensors, and ECG, heart rate (HR), breathing frequency (BF), and activity are monitored during exercise. This information is streamed live to a mobile device (PDA) that processes these parameters.

METHODS

A phase-I study was performed to evaluate feasibility, function, and reliability of this GEX device and compare it to conventional cardiac exercise testing (CPX, spiroergometry) in 50 patients (seven women, mean ± SD age 69 ± 9 years, body mass index 26 ± 3 kg/m(2), ejection fraction 58 ± 10%). ECG, HR, and BF were monitored using standard equipment and the GEX device simultaneously. Furthermore, HR recorded on the PDA was compared with CPX measurements.

RESULTS

The fit of the shirt and the sensor was good. No technical problems were encountered. All occurring arrhythmia were reliably detected. There was an acceptable comparability between HR on the GEX device vs. CPX, a good comparability between HR on the PDA vs. CPX, and a moderate comparability between BF on the GEX device vs.

CPX CONCLUSIONS

Comparability between CPX and the GEX device was acceptable for HR measurement and moderate for BF; arrhythmias were reliably detected. HR processing and display on the PDA was even better comparable. The whole system seems suitable for monitoring home-based CR. Further studies are now needed to implement training prescription to facilitate individual exercise.

摘要

背景

参与Ⅲ期心脏康复（CR）的比例仍然较低，但在有监督的家庭心脏康复中，依从性可能会得到改善。需要新的技术方法来对个体运动计划的安全性和执行情况提供充分监督。

设计

新设计的闭环工具，即HeartCycle的引导式运动（GEX）系统，将在基于运动的心脏康复过程中为专业人员和患者提供支持。患者穿着带有内置无线传感器的专用衬衫，在运动过程中监测心电图、心率（HR）、呼吸频率（BF）和活动情况。这些信息实时传输到处理这些参数的移动设备（个人数字助理）上。

方法

进行了一项Ⅰ期研究，以评估该GEX设备的可行性、功能和可靠性，并将其与50例患者（7名女性，平均±标准差年龄69±9岁，体重指数26±3kg/m²，射血分数58±10%）的传统心脏运动测试（心肺运动试验，运动心肺功能测试）进行比较。使用标准设备和GEX设备同时监测心电图、心率和呼吸频率。此外，将个人数字助理上记录的心率与心肺运动试验测量值进行比较。
