Keikku electronic stethoscope for recording heart sounds and detecting murmurs and wheezing

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective, open-label, controlled investigation will enroll 149 participants from newborns through age 99 at a single site in Lima, Peru. Each participant will have sequential auscultation at four standard precordial locations using the Keikku electronic stethoscope (with Bluetooth headphones) and a conventional stethoscope performed by a second, blinded physician. Physicians will independently record whether a murmur is present and rate acoustic quality on a 5-point Likert scale, while researchers monitor for device issues or adverse events. The study compares the diagnostic findings between the digital device and standard analog auscultation without automated interpretation of recordings.
