Methods of Recording Electrocardiogram (With Diagram) | Instruments | Biology
Though Waller (1887) first recorded the electrocardiogram yet Einthoven (1903) was the real father of the electrocardiogÂraphy. His method of recording E.C.G. through string galvanometer was followed until 1930 when it was largely replaced by the amplifier - driven oscillograph provided with direct ink recording. PrinÂciples upon which the string galvanometer was based are as follows if an electrical current [...]
