Accuracy of detecting irregular cardiac rhythms via telemedicine.
We evaluated the accuracy of an electronic stethoscope in the detection of irregular cardiac rhythms. Ten patients with either normal sinus rhythm or atrial fibrillation previously documented by electrocardiogram (ECG) were recruited from a local retirement community. Six senior family medicine resident physicians were asked to assess the cardiac rhythms of the subjects as either regular or irregular, in both a telemedical and an in-person examination. An ECG was obtained simultaneously as the gold standard. Forty-five of the 60 in-person assessments were correct, as were 49 of the 60 telemedicine assessments. The difference was not significant. Physician confidence in telemedical examination did not affect the accuracy of examination. The results of this study suggest that telemedicine-directed auscultation of patients may be just as successful as inperson examination for the detection of cardiac arrhythmias.
