Finding the Rhythm: Cardiac Pacing Techniques in the Modern Era

When the normal cardiac rhythm is changed or is very slow, the answer frequently comes in the form of pacemakers – devices that send small electrical impulses to the heart muscle to maintain a suitable heart rate or to stimulate the ventricles. They artificially stimulate the heart and were born out of a necessity to prevent catastrophic bradycardic events. 

The initial pacemaker systems were large, bulky external devices. However, advancements in technology allowed for the development of internally powered, fully implantable devices. Further advancements resulted in even more complex, programmable devices. In recent years, the role of implantable pacing devices has expanded beyond the arrhythmia horizon. Modern pacemakers’ functions include various modes of dual-chamber pacing, rate-response algorithms with dual sensors for optimum physiological response, cardiac resynchronization therapy (CRT), arrhythmia-prevention algorithms, antitachycardia pacing, and hemodynamic monitoring. Modern pacemakers also offer “physiological pacing” algorithms that minimize ventricular pacing and reduce the incidence of atrial fibrillation significantly. The approach to cardiac pacing is continually shifting and evolving and now there are even leadless pacemakers. These are small, self-contained devices that are inserted in the right ventricle of the heart of patients who need single-chamber pacing only. 


Radu Vătășescu

Radu Vătășescu specializes in cardiac electrophysiology and invasive cardiac procedures. He is an Associate Professor of Cardiology at the University of Medicine and Pharmacy “Carol Davila” in Bucharest. He also works as a Consultant Cardiologist and Internal Medicine Doctor at Floreasca Clinical Emergency Hospital and is the Head of the Clinical and Electrophysiology Lab at the hospital. Since 2018, he is also the coordinator for the National Certificate of Invasive Cardiac Electrophysiology. 

To date, Prof. Vătășescu has performed at least 4470 radiofrequency ablations and 3500 pacemaker and ICD implants. He currently serves as a Fellow of the European Heart Rhythm Association (EHRA), as well as the American Heart Association (AHA) and Heart Rhythm Society (HRS). He also served as the coordinator of the EHRA Committee of the National Cardiology Societies of Eastern Europe, President of the Working Group for Cardiac Arrhythmias of the Romanian Society of Cardiology , as well as Secretary of the Working Group for Cardiac Arrhythmias of the Romanian Society of Cardiology.
