Wearable-based signals during physical exercises from patients with frailty after open-heart surgery

Daivaras Sokas, Monika Butkuvienė, Egle Tamulevičiūtė-Prascienė, Aurelija Beigienė, Raimondas Kubilius, Andrius Petrėnas, Birutė Paliakaitė

A data collection contains a wearable-based electrocardiogram and triaxial acceleration signals of 80 elderly patients with frailty after an open-heart surgery. The signals were collected while the patients were performing a series of exercise tests.

Estimating Activity from Instantaneous Heart Rate

Using only a heart rate time series, it is possible to measure a number of features that reflect the level of physical activity. Here we provide software for deriving an "activity index" based on measurements of mean heart rate, total powe…

Is the normal heart rate chaotic?

George Moody

In its June 2008 issue, the editors of Chaos announced a new feature, "Controversial Topics in Nonlinear Dynamics". The first controversial topic to be aired is "Is the Normal Heart Rate Chaotic?". This project provides data to explore this question.
