Diagnostic study reveals high diagnostic accuracy for e-mailed heart murmur recordings in children, suggesting telemedicine safely minimizes unnecessary specialist referrals.

Key Points

To evaluate the clinical quality and diagnostic accuracy of using an electronic sensor-based stethoscope to record and email heart sounds for remote pediatric murmur assessment.
Heart sounds from 47 patients (7 with no murmur, 20 with innocent murmurs, and 20 with pathological murmurs) were recorded using a sensor-based electronic stethoscope and emailed to a central computer.
Recordings were repeated to produce 100 cases distributed on compact disc to four cardiologists for blinded, independent evaluation of murmur status, diagnostic certainty, assessment time, and referral decisions.
Cardiologists evaluated cases in a mean of 2.1 minutes, demonstrating a mean sensitivity of 89.7% and specificity of 98.2% for detecting murmurs.
Observer consistency was high, with an inter-observer agreement kappa of 0.81 and an intra-observer agreement kappa of 0.87.
Cardiologists recommended specialist referral for 93.4% of pathological murmur cases compared to 12.6% of innocent murmur cases.
