on (May 18, 2025) in the presence of the head of departments and lecturer a symposium entitled (Pacemaker: Principles, Clinical Applications, and Future Innovations), was presented by (Asst. Lect. Layla Mohammed Salih) from the Collage Nursing , Where it has been explained about, Pacemaker has become a fundamental intervention in the management of cardiac arrhythmias, particularly Brady arrhythmias and conduction system disorders. In this seminar we will explore the foundational principles of pacemaker technology, including the physiological rationale for pacing, device types, and operational mechanisms. Emphasis is placed on clinical applications, such as the use of single- and dual-chamber pacemakers, biventricular devices for cardiac resynchronization therapy (CRT), and emerging leadless systems. The seminar also addresses current challenges in pacemaker management, including complications, patient education, and follow-up protocols. Furthermore, it highlights future directions in cardiac pacing, focusing on technological advancements such as artificial intelligence integration, remote monitoring, energy-efficient designs, and next-generation smart devices.. At the end of the Symposium a set of questions and answers were raised on this subject By bridging foundational knowledge with clinical practice and innovation, this seminar aims to provide audience with a comprehensive understanding of pacemaker therapies and their evolving role in modern cardiology.
