Cardiovascular Monitoring Using Earphones and a Mobile Device
Frequent and non-invasive cardiovascular monitoring is important in surveillance for cardiovascular catastrophes and treatment therapies of chronic disease. Resting heart rate, one of the simplest cardiovascular parameters, is an independent risk factor (comparable with smoking, high blood cholesterol or hypertension) for cardiovascular disease. In particular, the association between accelerated resting heart rate and mortality has been observed in general populations, elderly subjects, as well as patients with hypertension, heart attack or coronary artery disease. As such, long-term monitoring of resting heart rate has important prognostic implications and provides an index of efficiency of therapy.
