If it's at a positive potential, it shows a positive reading. And if it's at a negative potential, it shows a negative reading. If the potential on both ends is the same, it shows no reading. It can record only that portion of the electrical activity that falls parallel to the direction of the electrode placement. The perpendicular activities, are not recorded. In the heart, the activities happen in many directions in three dimensions. So for better mapping of these activities, we use multiple leads. Three standard-bipolar limb·leads are created on the coronal plane, by connecting electrodes at both arms and the left leg. These three connections represent the tips of Einthoven's triangle around the heart. 3 augmented-unipolar limb·leads are created using the same electrodes. Each augmented lead, uses one of these electrodes as the positive end, and a combination of the remaining two as a negative end. For 6 chest·leads or precordial·leads on the transverse plane, a positive electrode is placed on the chest, at different points around the heart. And they all use a common negative connection obtained by combining all three electrodes on the limbs. This is equivalent to putting their negative electrodes in the middle of the heart. Each of these 12 leads records the heart's activity from a unique angle. So some areas are better recorded in some leads than others. In normal ECG, the P wave is produced by atrial depolarization, the QRS complex is produced by ventricular depolarization. Atrial repolarization occurs along with the QRS complex, so it's obscured. Ventricular repolarization produces the T wave. Different intervals studied in ECG are the P-Q interval or PR interval, QT interval, ST segment, and RR interval.
