Shows heart rhythm.: This shows your heart rhythm and can indicate whther your heart if working properly. It can show if you had a heart attack, or an irregular rhythm the can lead to a heart issue. That's why people as they get older need to get this to check up on how their heart is doing.

ECG: Ecg shows the hearts electrical activity. It diagnoses rhythm and suggests other heart information.
