Biography and Research Information

OverviewAI-generated summary

Hakan Paydak, M.D. serves as Professor of Medicine and Director of the Cardiac Electrophysiology Program and Laboratory at the University of Arkansas for Medical Sciences. His medical training includes graduation from Hacettepe University Faculty of Medicine in Turkey, followed by cardiology and clinical cardiac electrophysiology fellowships at Case Western Reserve University Hospital and the University of Chicago Hospital. Before joining UAMS in 2009, Dr. Paydak was on staff at the Medical College of Wisconsin.

Dr. Paydak's research and clinical focus includes the study and treatment of cardiac arrhythmias. He is board-certified in internal medicine, cardiovascular diseases, and clinical cardiac electrophysiology, and holds fellow designations from the American College of Cardiology and the Heart Rhythm Society. His work has been published in numerous peer-reviewed journals, with a total of 158 publications and 2,259 citations, contributing to his h-index of 20. He is recognized as a highly cited researcher.

His recent publications investigate a range of topics within cardiovascular medicine, including case reports on vagal nerve stimulator complications, meta-analyses on cardioversion techniques for atrial fibrillation, and studies on anticoagulant use in conditions such as left ventricular thrombus and following catheter ablation. He has also explored the role of medications in managing COVID-19 related cardiac conditions, such as theophylline for sinus bradycardia and statin use in severe COVID-19. Dr. Paydak collaborates with researchers at the University of Arkansas for Medical Sciences, including Subodh Devabhaktuni, Srikanth Vallurupalli, J. Paul Mounsey, and Khalid Sawalha.

Research Interests

12 YEARS OF ELECTROPHYSIOLOGY RESEARCH AT UAMS I have had 60 of my 69 peer reviewed publications, with the guidance of Dr. Jay Mehta and contributions of many faculty, fellows, residents and medical students. As a result of this teamwork, we have been honored to receive the Dr. James Marsh Research Award in 2021. Our two main manuscripts were database driven large population studies that were published in Circulation. However, we have also published many purely UAMS patient database driven studies. Our recently published case report in JAMA has paved the way for our study titled: “The Sensitivity of Graphic Trends in Differentiating Sinus and Supraventricular Tachycardia”, which will be published in the Journal of Electrocardiology. The future of our Electrophysiology research efforts at UAMS will utilize Artificial Intelligence to guide us place the left ventricular lead to the best spot in the heart in our NIH sponsored study.; Cardiac Electrophysiology; Atrial Flutter; Atrial fibrillation; Cardiac Arrhythmias; Antiarrhythmic Drugs; Ablation, Radiofrequency Catheter
