CardiacProfileR: an R package for extraction and visualisation of heart rate profiles from wearable fitness trackers

A heart rate profile is constructed from continuous measurement of heart rate before, during and after exercise, typically in the context of an exercise stress test. It contains important clinical parameters such as resting heart rate, maximal heart rate during exercise, and decrease of heart rate in the recovery phase. An increase in resting heart rate, a decrease in heart rate elevation in response to exercise, and a delay in heart rate recovery are significant predictors of sudden death (Cole et al. 1999; Jouven et al. 2005). These measurements, when derived from a controlled exercise stress test regime, have high intra-individual reproducibility over 3 years, indicating their usefulness as a diagnostic tool (Orini et al. 2017).
Heart rate parameters and profiles have been measured and constructed with exercise stress tests under controlled environments. This is often performed with a treadmill in a laboratory setting. With increasingly widespread availability of...
