Objective: To address whether transtelephonic electrocardiographic monitoring (TEM) of patients with chronic cardiac diseases, being exercised in public gyms, is safe and efficacious. Design: Data were obtained from 91 patients (72 men and 19 women; with a mean (SD) age of 56 (6) years and over a total of 11 820 exercise hours) with coronary heart disease and/or chronic heart failure (</= stage III NYHA (New York Heart Association)), who were referred for cardiac exercise rehabilitation (phase III). Method: Twelve-lead electrocardiograms of indicated patients were transmitted from the qualified trainers in real time by standard telephone lines and were evaluated by the medical staff at the base. The TEM kits contain a telemedicine 12-lead electrocardiographic unit, a telephone modem, a computer receiver with special operating software and a laser printer. As soon as the ECG was monitored and diagnosed, the cardiologist contacted the exercise trainer and provided all the necessary instructions for intervention. Results: In total, 280 cases were monitored. Successful TEM was reported in 99.3% of the cases. The mean (SD) time from ECG recordings to final interventions was estimated at 294 (13) s. The patients were referred for TEM during or soon after exercise sessions, because of chest pain (36% of the TEM cases), palpitations (33%), dizziness (12%), unexpected fatigue (9%), hypertensive crises (7%) and other disorders (3%). Ischaemic ECG changes were recorded in 14 cases with thoracic pain and arrhythmias in nine patients with palpitations. In only one case was a medical emergency reported and an ambulance response required. Conclusion: These data demonstrate that TEM provides a workable facility in cardiac rehabilitation for monitoring patients who are exercising in gyms.
