ECG (Electrocardiography) or ekg ( from the German Elektrokardiogramm ) is a transthoracic (across the thorax or chest) interpretation of the electrical activity of the heart over a period of time.(From Wikipedia).I remember I had to underwent before because I was suffering with unbearable headache and the doctor advise me to have one just to make sure what’s going on. But unlike before when I needed to go to the hospital to have it done,but now,you can just call your doctor to do it at home with their portable ekg machine and also there’s the pc-based too.

Wow! talk about hi tech at its finest!!!!
