Analysis of telemetry, on-line and non-telemetry data for characterization of the physical activity of patients with heart failure

Introduction: Several studies have demonstrated that the prevalence of heart disease can be accounted for between 0.4 and 2% in developed countries. Aim: The present study aimed to use the PA% of the telemetry data to estimate the 6-minute walk test result. Method: 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. Using the two sets of values describing physical performance, linear regression was calculated providing a mathematical equation, thus, the Physical Activity % value is used to estimate the distance traveled over a 6-minute walk test. Results: On further data analysis, we have come to the conclusion that the distance walked during the six-minute-long test may be measured by PA% from the data of CRT device. 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.
