BACKGROUND: Some healthcare facilities lack professionals qualified to interpret electrocardiograms. We aimed to assess the usefulness of transtelephonic electrocardiography in combination with patients' clinical histories in the diagnosis and management of patients with acute chest pain in out-of-hospital healthcare facilities with personnel without expertise in cardiology or electrocardiography. METHODS: Data from 506 consecutive patients (53.9 ± 16.2 years old) referred from 55 healthcare facilities without professionals specialized in cardiology or electrocardiography form the basis of analysis. Patients were classified into 2 groups according to the results of transtelephonic electrocardiography: (A) patients without electrocardiographic abnormalities (n = 445) and (B) patients who presented abnormalities suggesting a cardiac origin (n = 61) of the chest pain. The presence of risk factors was evaluated by multivariate analysis. RESULTS: The following risk factors were independent predictors of electrocardiographic abnormalities: male gender (P = .006), diabetes mellitus (P = .0001), and dyslipidemia (P = .001). The multivariate analysis yielded a high degree of specificity (99.6%). Follow-up visits confirmed the noncardiac origin of pain in 432 patients (97%) in group A and the cardiac origin of pain in 59 patients (97%) in group B. CONCLUSIONS: Transtelephonic electrocardiography combined with awareness of the risk factors of patients presenting with chest pain is useful for the diagnostic management of these patients in health care facilities without the means to interpret electrocardiograms.
