ECG Signals

what is ECG?

An electrocardiogram (ECG) is a simple test that can be used to check your heart's rhythm and electrical activity.

How can we record ECG signal?

Electrical signals are produced by contractions in the heart walls which drive electrical currents and create different potentials throughout the body. By placing electrodes on the skin.

How can we use ECG signal?

There are a lot of medical infotmation that we can understand from ECG signal and beside them there is a fact that ECG signal is unique for every person so we can use to identify people.

for more information you can check Introduction to ECG signal processing slide at this repository.
