Heart pacemaker, X-ray
Heart pacemaker. Coloured chest X-ray showing a surgically-implanted heart pacemaker (red, centre right). The pacemaker supplies electrical impulses along leads (running to lower centre) to the heart to keep it beating regularly. It is fitted in patients with a malfunctioning sinoatrial node, the part of the heart that initiates each heartbeat, or those with a heart block impairing the nerve impulses generated by the node. Heart pacemakers may provide a regular impulse (fixed rate pacemaker) or discharge only when a heartbeat is missed (demand pacemaker)

EDITORS COMMENTS
This print showcases a remarkable medical breakthrough - a surgically-implanted heart pacemaker. The vivid colors of the chest X-ray draw our attention to the life-saving device, depicted as a vibrant red object in the center-right of the image. The purpose of this ingenious invention is to supply electrical impulses through leads that run towards the lower center, ensuring that the heart beats regularly. Patients with either a malfunctioning sinoatrial node or a heart block benefit greatly from this technology. The sinoatrial node is responsible for initiating each heartbeat, and when it malfunctions or nerve impulses are impaired by a heart block, these pacemakers step in to maintain cardiac rhythm. Heart pacemakers come in different types: fixed rate pacemakers provide regular impulses while demand pacemakers discharge only when there is a missed heartbeat. Both variations serve their crucial roles in helping patients regain control over their hearts' functioning. This photograph not only highlights the intricate wiring and artificial components of this life-sustaining system but also emphasizes its significance within modern medicine. It serves as an emblematic representation of cardiology's progress and dedication to enhancing patient care. Science Photo Library has once again captured an extraordinary moment in medical history, reminding us of humanity's relentless pursuit of innovation and improvement within healthcare systems worldwide.
