A visionary cardiovascular surgeon who pioneered modern pacemaker therapy in Serbia and beyond
In the landscape of modern medicine, few innovations are as elegantly life-sustaining as the artificial pacemaker. This remarkable device, which assumes the heart's vital electrical function, has preserved countless lives. Behind its integration into standard medical practice lies the story of Professor Dr. Milan H. Djordjević (1933-1993), a visionary cardiovascular surgeon whose relentless innovation and international collaboration helped pioneer modern pacemaker therapy in Serbia and beyond. His career, though cut short, resonates through the decades—a testament to how one dedicated scientist can shape the heartbeat of medical progress 6 .
Dr. Djordjević's work transcended technical implementation; he sought to understand, refine, and adapt cardiac electrostimulation to the unique needs of each patient, establishing a legacy that continues to throb in the corridors of cardiology departments today.
Pioneering work in cardiac electrostimulation
Milan H. Djordjević's journey into medical history began in Smederevska Palanka in 1933. He graduated from the University School of Medicine in Belgrade in 1961 and honed his skills in general surgery at the II Department of Surgery in Belgrade. His mentor, Professor Vojislav Stojanović, quickly recognized the young surgeon's exceptional aptitude for both clinical work and research 6 .
This foundation set the stage for a career marked by "original ideas and permanent search for new possibilities," particularly in the multidisciplinary field of cardiac electrostimulation. His doctoral thesis, "The Role of Venous Valvula in Aortocoronary Bypass During Increased Coronary Flow" (1976), demonstrated his deep commitment to understanding the intricate physiology of cardiovascular blood flow and surgical outcomes 6 . This early academic rigor would become the hallmark of his subsequent groundbreaking work.
Born in Smederevska Palanka
Graduated from University School of Medicine in Belgrade
Defended doctoral thesis on aortocoronary bypass
Professor Djordjević's most enduring contributions lay in establishing and advancing pacemaker therapy. In 1981, he founded the Bypass Centre of the Republic of Serbia, which later evolved into the Yugoslav European Reference Centre for pacemaker therapy 6 . This center became a hub of excellence, centralizing expertise and elevating the standard of cardiac care for the entire region.
His pioneering spirit was most vividly demonstrated when he became the first surgeon in Serbia to implant an implantable cardioverter defibrillator—a procedure performed a mere two months after the first such implantation in all of Europe 6 . This remarkable feat highlighted not only his technical prowess but also his dedication to ensuring his patients had access to the very latest life-saving technologies without delay. His work was recognized with "The October Award of the City of Belgrade" for science in 1981 6 .

Professor Djordjević's research was characterized by its breadth and innovation. He consistently pushed the boundaries of what was possible in cardiac care 6 . His reputation for excellence led to his election to the Nucleus of the European Working Group for Heart Electrostimulation and Electrophysiology, where he would eventually serve as its president, fostering international collaboration and setting continental standards in the field 6 .
Studying how the heart's response to pacing changes over time to improve long-term therapy.
Developing ways for pacemakers to respond to a patient's physical activity levels without relying on atrial signals.

| Research Area | Primary Focus |
|---|---|
| Stimulation Thresholds | Understanding long-term heart tissue response to pacing |
| Sensor Technology | Adapting pacemaker rhythm to patient activity without atrial input |
| Spinal Cord Stimulation | Investigating new therapies for terminal vascular diseases |
| Device Safety | Studying electromagnetic interference on pacemaker function |
| Surgical Materials | Developing improved biologic-synthetic vascular grafts |
While Dr. Djordjević oversaw countless pacemaker implantations, his most technically ambitious feat was the implantation of an implantable cardioverter defibrillator (ICD). This procedure in the early 1980s was a monumental undertaking.
The implantation of an ICD is far more complex than a standard pacemaker. The system consists of a pulse generator and one or more leads that monitor the heart's rhythm. If the device detects a life-threatening arrhythmia, it delivers a high-energy shock to restore a normal heartbeat. In Djordjević's era, this required:
Thoracotomy Approach
Opening the chest under general anesthesia
Epicardial Lead Placement
Attaching leads to the heart's surface
Pulse Generator Implantation
Placing generator in abdominal pocket
System Testing
Testing device function with induced arrhythmia
The successful execution of this procedure just two months after its European premiere was a resounding success. It proved that Serbian medical institutions could operate at the forefront of global cardiology.
The scientific importance was profound:
This achievement was not an isolated event but part of a broader, systematic effort to build a center of excellence that would endure.
| Tool or Material | Function |
|---|---|
| Pacemaker with Epicardial Leads | Regulates heart rhythm via electrodes |
| Implantable Cardioverter Defibrillator (ICD) | Monitors rhythm and delivers shocks |
| Non-Atrial Sensors | Adapts pacemaker to patient activity |
| Biologic-Synthetic Grafts | Repairs or replaces damaged vessels |
| Electromagnetic Shielding | Protects devices from interference |
Professor Djordjević's stature made him a natural ambassador for Serbian medicine. He lectured worldwide—from Detroit and Houston to New York, Berlin, and Vienna—and served as an expert on cardiovascular diseases for the World Health Organization 6 . His scientific reputation was formally recognized with his election as a corresponding member of the Serbian Academy of Sciences and Arts.
Tragically, his life and work were cut short. He had been planning to organize a European congress on Pacemaker Therapy and Electrophysiology in Belgrade for 1993. However, political events in the region and his untimely death in Paris in January 1993 prevented this final ambition from being realized 6 . He was buried in Belgrade, leaving behind a discipline he had fundamentally helped to shape.
Professor Dr. Milan H. Djordjević is rightly remembered as the founder of modern clinical pacemaker therapy in his homeland. More than just a surgeon, he was a builder of institutions, an international collaborator, and a tireless innovator. His life's work ensured that the heartbeat of progress in cardiac care would continue strong, long after his own had stilled.
Lectured worldwide and served as WHO expert on cardiovascular diseases
