GENERAL KNOWLEDGE

Detailed explanation-1: -Willem Einthoven found the beat and built a machine that could measure the electrical current a heart creates. It weighed 600 pounds. An electrocardiogram-called informally an ECG or EKG-measures the small electric waves that a human heart creates. It’s been doing it for more than a century.

Detailed explanation-2: -He coined the term electrocardiogram for this process. Einthoven recognized differences in the records or tracings obtained from different kinds of heart disease. From 1908 to 1913 he studied the patterns of records of normal heart activity in order to gain precision in recognizing and interpreting deviations.

Detailed explanation-3: -Willem Einthoven is widely considered the father of the electrocardiogram (ECG). In 1912, he proposed a method of determining the electric axis of the heart by using an imaginary equilateral triangle connecting the limb leads, now known as Einthoven’s triangle.
