Anatomical correlate of permanent cardiac pacemaker

An incidental and interesting heart with artificial permanent cardiac Pacemaker was seen in a male adult cadaver in dissection hall during the routine dissection in the Anatomy department of GSVM Medical College, Kanpur, Uttar Pradesh, India. The case is reported for the academic interest of readers. Artificial Pacemaker is a device that provides electrical stimulation to cause cardiac contraction when intrinsic cardiac electrical activity is slow or absent. A pacemaker is composed of two parts, the pacing electrodes, or leads, which are wires that are inserted directly into the heart, and a pacemaker generator.

In the cadaver the pacemaker was implanted subcutaneously in the right Pectoral region inferior to the Clavicle .The lead was inserted into the heart through the Right Subclavian Vein. The terminal end of Lead was found in the apex of Right Ventricle. The size of the heart was measured with a vernier calliper. The cardiomegaly was found.
