In what year was the first electrocardiogram introduced in the United States?

The introduction of the first electrocardiogram (ECG) in the United States was a significant milestone in the field of cardiology. In 1909, Dr. Willem Einthoven, a Dutch physiologist and physician, made pivotal advancements in the electrocardiogram technology, leading to its widespread implementation in medical practice, particularly in the United States. Einthoven's work and the subsequent development of the string galvanometer allowed for the accurate recording of the electrical activity of the heart, fundamentally changing how cardiac conditions were diagnosed and treated.

The year 1909 is pivotal because it reflects the initial integration of this groundbreaking technology into clinical settings. Understanding this historical context emphasizes the evolution of cardiac monitoring and its impact on patient care, illustrating how the introduction of ECGs revolutionized the approach to diagnosing cardiac issues.
