Action Potential (AP) is electrical stimu- lation created by a sequence of ion fluxes through specialized channels in the membrane of cardiomyocytes that leads to car- diac contraction.


An electrocardiogram — abbreviated as EKG or ECG — is a test that measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or wave) travels through the heart.

-  By measuring time intervals on the ECG, a doctor can deter- mine how long the electrical wave takes to pass through the heart. 

-  By measuring the amount of electrical activity passing through the heart muscle, a cardiologist may be able to find out if parts of the heart are too large or are overworked. 

- Provides low-resolution information.
