Deflections In The Ecg Correspond To Electrical Events In The Heart

The record of the heart's electrical activity from the surface of the body is called an electrocardiogram (ECG). A typical ECG trace is shown in Fig. 2. For this recording, the positive electrode was placed on the left shoulder and the negative electrode was placed on the right shoulder, which is the standard lead I electrode placement. The activation sequence of the heart begins with action potentials within the sinoatrial (SA) node. No contribution from the firing of action potentials in the SA node can be seen in the ECG tracing because the mass of the SA node is too small. After activation of the SA node, action potentials propagate across the atria.
