Electrocardiogram (ECG) Front End


Electrocardiogram (ECG) Front End - Successfully meeting the signal acquisition challenge requires
knowledge of the signal source, good design practice, and ICs with appropriate characteristics, features
and performance.


Design Considerations


Signal Acquisition Challenges


The action potential created by heart wall contraction spreads electrical currents from the heart
throughout the body. The spreading electrical currents create different potentials at different points on the
body, which can be sensed by electrodes on the skin surface using biological transducers made of
metals and salts. This electrical potential is an AC s
