WebThe ECG trace reflects the net electrical activity at a given moment. Consequently, activity in one direction is masked if there is more activity, eg, by a larger mass, in the other direction. For example, the left ventricle muscle mass is much greater than the right, and therefore its depolarization accounts for the direction of the biggest wave. WebFeb 2, 2024 · There are numerous types of pacemaker, including atrial pacemakers that pace only the atria, ventricular pacemakers that pace only the ventricles, and pacemakers that pace both the atria and the ventricles.
