Official Description

The heart is talkative, murmuring joyfully, anxiously, enthusiastically, calmly, cheerfully, breathlessly, contentedly, or unhappily. It is not always easy to understand the language of the heart, but applying a stethoscope to the chest is undoubtedly exciting.

This app is designed to describe the pleasure of communicating with the heart; 50 phonocardiograms (PCGs) were selected from more than 5,000 recordings. Every PCG is shown with sound and echocardiography. In addition, 50 or more PCGs, along with sound, are available. The history of the stethoscope as well as the trivia of cardiac auscultation are also included.

It would be great if this app motivates people to learn about cardiac auscultation. I am grateful for all of the support I have received during the recording and interpretation of the PCGs at Matsushita Memorial Hospital. I welcome your comments, questions, critiques, feedback, corrections, stories, experiences, and anecdotes.
