The Heart

All animals’ heart is beating 1 billion times in a lifespan. Humans are an exception. Their heart is beating 2.6 billion times on average, thanks to developments in health treatments and sanitation¹. This website’s intention is to improve medical effectiveness in echocardiographic practice.

The Gear

Inge Edler (1911–2001) and Carl Hellmuth Hertz, the cardiologist-physicist team gave the world echocardiography in 1977², allowing nowadays cardiologists to touch the heart with their fingertips and see the living heart.

The Practice

Cardiac ejection fraction (EF) eyeballing may be the most accurate echocardiographic method for the assessment of left ventricular systolic function, compared to Simpson EF, wall motion score index, atrioventricular plane displacement and fractional shortening³.
