Hospital-based and telemonitoring guided home-based training programs: Effects on exercise tolerance and quality of life in patients with heart failure (NYHA class III) and cardiac resynchronization therapy. A randomized, prospective observation.

Cardiac resynchronization therapy with defibrillator function (CRT-D) along with an optimal medical therapy improves symptoms, cardiac efficiency, quality of life (QoL) and prognosis in patients with heart failure (CHF). The aim of the study was to assess effects of hospital-based and home-based/telemonitoring exercise training.
