The "Listening to the Heart" app is a comprehensive guide for learning cardiac auscultation (i.e. using a stethoscope) for the medical professional, paraprofessional or student.

Containing over 90 mini-lectures, with over 125 examples of actual heart sounds, defects and murmurs - along with illustrations and explanations - "Listening to the Heart" was developed by the late Dr. Daniel Mason (over a career spanning more than 50 years) to teach thousands of medical students, nurses and professionals how to use a stethoscope, and how to use it more effectively to aid in diagnosis and treatment.

Included in the app are:

With "Listening to the Heart" you can learn how to recognize heart defects more accurately, quickly and inexpensively, and improve your auscultation and diagnostic skills - right from your iPhone.

Also included is a unique acoustic analysis module that lets you record your own heart sounds - using your iPhone as a stethoscope - and compare them to the built-in library of exemplars collected by Dr. Mason.

The app also includes an on-board skills assessment called "What is your Diagnosis?” where you can test your ability to recognize heart sounds and defects correctly.
