Popis: Introduction The present study aimed to define changed in percentage physical activity from implanted devices using telemetry, and converting them into MET values (metabolic equivalent), in order to determine oxygen consumption during physical activity. Methods A total of seventeen patients with heart disease; 3 females and 14 males; age: 57.35 yrs ± 9.54; body mass 98.71 ± 9.89 kg; average BMI 36.69 ± 3.67 were recruited into the study. The measured values from Cardiac Resynchronisation Therapy devices and outer accelerometers (ActiGraph GT3X+) were studied over a 7-day time period. Using the two sets of values describing physical performance, linear regression was calculated providing a mathematical equation, thus, the Physical Activity values in percentage were converted into MET values. Results During the 6-min walk test (6MWT) the patients achieved an average of 416.6 ± 48.2 m. During 6MWT the measured values averaged at 1.85 ± 0.18 MET’s, and MET values averaged at 1.12 ± 0.06 per week. It clearly shows that this test is a challenge for the patients compared to their daily regular physical activity levels. Conclusions With our method, based on the values received from the physical activity sensor implanted into the resynchronisation devices, changes in patients’ health status could be monitored telemetrically with the assistance from the implanted electronic device.
