Electrocardiogram (Definition)

Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more

Does an ECG pick up any palpitations happening at the time of the test?

Help me doc, i am really terrified. i went to do an ECG test and my result is as follows P WAVE ENLARGEMENT OTHERWISE NORMAL ECG.. please help me?

Oh, and don't smoke if you value your heart and your circulation...to other important areas. ...Read more
