This subanalysis focuses on 386 patients (aged 62\u00a0\u00b1\u00a011\u00a0years, LVEF 31\u00a0\u00b1\u00a07%) randomized to HCTR. HCTR was telemonitored with a device allowing to record 16\u2010s fragments of ECG and to transmit the data via mobile phone network to the monitoring center.<\/jats:p><jats:p>ResultsIn 386 patients, 16,622 HCTR sessions were recorded and 66,488 ECGs fragments were evaluated. Sinus rhythm was present in 320 (83%) and permanent atrial fibrillation (AF) in 66 (17%) patients, respectively. The most common arrhythmias were ventricular and atrial premature beats, recorded in 76.4% and 27.7% of the patients, respectively. Non\u2010sustained ventricular tachycardia (21 episodes in 8 patients) and paroxysmal AF episodes (6 in 4 patients) were rare. None of the analyzed demographic and clinical characteristics was predictive for onset of the new arrhythmias on exercise.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Telerehabilitation in HF patients was safe without the evidence for symptomatic arrhythmias requiring discontinuation of telerehabilitation. Only one mildly symptomatic paroxysmal AF episode led to the short\u2010term suspension of the training program. The most common arrhythmias were atrial and ventricular premature beats. These arrhythmias did not result in any changes in rehabilitation and therapy regimens.<\/jats:p><\/jats:sec>","DOI":"10.1111\/anec.12887","type":"journal-article","created":{"date-parts":[[2021,9,9]],"date-time":"2021-09-09T13:42:20Z","timestamp":1631194940000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Assessment
