ClinConnect Summary

Before and after the Rehabilitation Program (RP), all patients underwent a 24-hour ECG recording, an echocardiography, a cardiopulmonary exercise test.

The RP consisted of 2 types of exercise training according to the randomization:

1. a short-high intensity interval exercise with passive recovery
2. a classical moderate and continuous exercise training at 60% of peak power output

The RP lasted 4 weeks.
