Electrocardiogram (ECG) detects the electrical activity of the heart. It is an essential test, which allows cardiac physiologist or a doctor to observe the rhythm of the heart beat and monitor the conditions carefully. Heart problems such as Arrhythmias can be detected using the ECG.
The process by which an ECG is carried out is that several electrodes are put on your arms, chest and legs. A gel is usually used to make sure that the contact between the electrode and the skin is good so that the electrical signals of each heart beat can be detected[1][2].
If some abnormality happened to Na+ or K+ channel, it will lead to channelopathies, in which some abnormal curve of ECG will happened.
