The Portable Heart Sounds Reference Library

The famously popular iMurmur Heart Sounds Teaching App, now with major upgrades:



This is a great pocket reference for both teachers and students of cardiac sounds, as well as practicing physicians for patient education. iMurmur includes the following for each sound:

* Description of sound 
* Phonocardiogram
* Diagram of sound morphology
* Where To Listen
* Clinical Notes
* Pathophysiology
* Associated Pathology


We at Thinklabs liked iMurmur 1.0 so much that we bought the App! We kept the great features, and upgraded the sound library using actual patient recordings, to give you the most realistic learning experience possible. We've also added real Phonocardiograms that you can scroll and edit as you would actual patient recordings on iMurmur's clinical tool partner,Thinklabs Stethoscope App
