Semi-superrsed home exerlise program based on computer-based telemetig system with a step machine in patients with myccarhal in fardic

心肌梗死患者的家庭运动方案能有效地提高患者的运动能力和生活质量。然而，没有有效的方法来监测病人的临床状态或传达医生的指示到家庭设置。为了解决这些问题，我们开发了一个以计算机为基础的自动化遥测系统，该系统由中央计算机和外围计算机以及电话线组成。首先，我们试图澄清步进机是否对心肌梗死患者的运动训练有用。据此，对部分心肌梗死患者出院前的峰值摄氧量（峰值VO2）和无氧阈值（AT）进行评估。在家中，患者使用踏步机进行10或15分钟的锻炼。患者运动前后的血压、脉搏、心电图等数据存储在外围计算机中，中央计算机通过电话线自动检索数据。如果当前心率低于at时的心率，注意到血压的极端变化或出现危险的心律失常，则在外围计算机的显示器上指示适当的指示。按照这些指示，患者继续进行了6个月的家庭锻炼计划。所有患者的峰值VO2和AT均显著升高。基于计算机的自动遥测系统与踏步机相结合，有助于在家中有效地处方和监测锻炼计划。

Home exercise programs for patients with myocardial infarction effectivly improve their exercise capacity as well as quality of life.However, there are no efficient methods for monitoring the patient's clinical status or conveying the physician's instructions to the home settin.To resolve these problems, we developed a computer-based, automated, telemetry system comprised of central and peripheral computers and telephone line. At first, we attempted to clarify wherthr a step machine is useful for exercise training in patients with myocardial infarction.Accordingly, some myocardial infarction patients were evaluated for peak oxygen uptake (peak VO2) and anaerobic threshold (AT) before hospital discharge.At home, the patients performed 10 or 15 minutes exercise using a step machine.Patient data including blood pressure, pulse rate, and electrocaediogram before and after exercise were stored in the peripheral computer, and the central comquter automatically retrieved the data through the phone line.If the current heart rate was less that the heart rate at AT,extreme changes in blood pressure were noted or dangerous arrhythmias appeared, appropriate instructions were indicated on the display of the peripheral comquter.Following these instructions, the patients continued home exercise programs for 6 months. Both peak VO2 and AT increased significantly in all patients.The computer-based automated telemetry system comdined with a step machine facilitated effective prescription and monitoring of exercise programs at home.
