Question

ECG was developed by

• A. \( \text{Wilhelm His} \)
• B. \( \text{Steward} \)
• C. \( \text{Willem Einthoven} \)
• D. \( \text{Hubert Mann} \)

Hint:

Remembering key figures and their contributions in biomedical engineering is important. Willem Einthoven's development of the ECG was a monumental step in diagnostic medicine, enabling non-invasive assessment of cardiac function and leading to significant advancements in understanding heart diseases. His work laid the foundation for all subsequent ECG technology and interpretation.

Answer 1

The Correct Option is C

1. Wilhelm His: He is known for discovering the bundle of His, an important part of the heart's electrical conduction system, but he did not develop the electrocardiogram itself.
2. Steward: This name is not primarily associated with the development of the ECG.
3. Willem Einthoven: A Dutch physiologist, he is widely recognized as the father of modern electrocardiography. He developed the first practical electrocardiograph, the string galvanometer, in 1903, and accurately described the P, Q, R, S, and T waves. He was awarded the Nobel Prize in Physiology or Medicine in 1924 for his seminal work.
4. Hubert Mann: He made contributions to the field of electrocardiography, particularly in vectorcardiography, but he is not credited with the initial development of the ECG.

Therefore, the correct answer is Willem Einthoven.
