Image finding: Pacemaker placement



The position of the normal pacemaker takes a characteristic course when examined on both anterior and lateral views. On the anterior view the tip of the pacer should be visible just to the left of the spine but not all the way to the apex of the left ventricle at the cardiac border.

The lateral film should show the tip in the cardiac silhouette anteriorly rather than posteriorly in the lower part of the heart.
