I am overwhelmed by the magnificent images of the universe. It is also scolded by the mysterious appearance of deep sea fish. It is because it has persuasive power that does not require words in the image. The electrocardiogram is also true. It is an instant miracle that the heart's electrical activity weaves.

At Matsushita Memorial Hospital, we have a study group on electrocardiograms (Matsushita cardioden) every week. The online version is this application. The motto is "Learning the electrocardiogram happily". I'm glad if this application is useful.

First, an electrocardiogram is presented. Please check the one-line interpretation after that. We aimed at usability like "English word card". The diagnosis name is based on the 3rd edition of Cardiology Glossary. The policy is our hospital standard.
