For hundreds of years, doctors have listened to the heart to understand how it’s working. Those familiar “lub-dub” sounds come from your heart valves opening and closing, and your heart chambers filling and emptying with blood. To a trained ear, healthy heart sounds follow a clear and consistent pattern.

When that pattern changes, it can signal a problem. Irregular timing between beats may suggest a rhythm issue. A sound that is too loud or too faint can point to a valve problem. Extra sounds between the lub and dub may indicate a murmur or other structural change. These clues are often subtle, and easy to miss during short, infrequent exams.

Medaica makes these heart sounds easier to capture, measure, and track over time. By extracting and filtering the audio, small changes become clearer. Assisted AI helps flag specific sounds or patterns, supporting cardiologists as they review the recordings. The result is more insight, earlier awareness, and decisions guided by clinicians, using better data.
