Overview
Brief Summary
Heart rate variability (HRV) is impaired in patients after myocardial infarction. Most studies so far have proved chronic beneficial effects of different types of exercise on HRV parameters. Data on acute effects of different types of exercise training (e.g. high intensity interval training [HIIT] and moderate intensity continuous training [MICT]) is scarce.
Patients in the study will perform both HIIT and MICT in a random order and in-between break of at least 48 hours. A 5-minute high resolution ECG recording will be performed before and immediately after both HIIT and MICT.
