Historical Significance of ECG Technology

The electrocardiogram (ECG) has played a pivotal role in the medical field due to its ability to non-invasively record the electrical activity of the heart. Developed decades ago and popularized by Eindhoven's Nobel Prize-winning work in 1924, the ECG utilizes surface electrodes to deliver critical cardiac data without the need for radiation or imaging. Its accessibility means that ECGs are found in almost every medical facility globally, allowing clinicians to diagnose a variety of heart conditions effectively. The longstanding use and ongoing refinement of ECG interpretation have marked it as a foundational technology in cardiovascular care.
