CONCLUSIONS Current evidence suggests that D-PA may be useful for assessing physical activity and predicting clinical outcomes in patients with cardiovascular implantable electronic devices when combined with other device parameters .
BACKGROUND  Physical activity  is predictive of cardiovascular outcomes in patients with cardiovascular implantable electronic devices , yet it is not regularly assessed in routine care .
Current-generation cardiovascular implantable electronic devices , however , continuously monitor patient activity through a built-in accelerometer , which provides new opportunities to remotely assess patient activity , detect changes in clinical status , and incorporate these data in risk stratification models .
This review critically examines the literature on device-measured physical activity ( D-PA ) , with a focus on identifying method ological issues that may affect interpretation of study results .
Monitoring of physical activity and heart rate variability in patients with chronic heart failure using cardiac resynchronization devices.
Cardiac resynchronization therapy ( CRT ) devices not only deliver effective treatment but may also serve as valuable diagnostic tools in heart failure management . In the present study , the minutes of daily physical activity and heart rate variability , measured by sensors incorporated into such a device , reflected the effects of CRT and were related to New York Heart Association functional class
