How is an electrocardiogram used for atrial flutter?

ANSWER

The electrocardiogram (ECG) measures and records the electrical impulses that control the beating of the heart.

The ECG highlights irregularities in these impulses and abnormalities in the heart.

In arrhythmias, the ECG tracings can help pinpoint the type of arrhythmia and where in the heart it comes from.

ECG also shows signs of heart attack, heart ischemia, conduction abnormalities, abnormal heart enlargement (hypertrophy), and even certain chemical abnormalities in the heart tissue such as potassium and calcium.
