New Insights in Pediatric Holter Monitoring and Interpretation

Gabriel Cismaru MD, PhD is a qualified cardiologist working at the Rehabilitation Hospital Cluj-Napoca in Romania. He obtained his PhD in medicine with a research thesis on electrophysiology and pro-arrhythmic drugs. He began his electrophysiology fellowship at the Institut Lorrain du Coeur et des Vaisseaux Louis Mathieu, France, after finishing his cardiology certification in Clermont-Ferrand and Dinan, France. He began working in the Rehabilitation Hospital's Electrophysiology Laboratory in 2011. He is an experienced surgeon who implants pacemakers, CRTs, and ICDs, as well as performing catheter ablation of supraventricular and ventricular arrhythmias. He is qualified in pediatric cardiology, regularly performing device implantation and catheter ablation in children. Dr. Cismaru has authored or co-authored peer-reviewed publications and book chapters on cardiac pacing, defibrillation, electrophysiological studies, and catheter ablation. He is the author of the book Arrhythmia Induction in the EP Lab," now in its fourth edition.Dr. Simona Sorana Cainap MD, PhD is an Associate Professor in Pediatric Cardiology at the University of Medicine and Pharmacy Cluj Napoca, where she serves as an expert on pediatric cardiology, lecturers, and makes use of her extensive echocardiography competence. She is qualified as a primary pediatrician, with training in juvenile diabetes. She enjoys echocardiography, Holter monitoring, training resident doctors, and pursuing clinical work. She has received a vast amount of additional training, and has published widely in peer-reviewed journals.Cecilia Lazea MD, PhD is a Associate Professor of Pediatrics based in Cluj-Napoca, Romania. Her expertise is pediatric cardiology, and she has made significant contributions to the field through her research and clinical practice. She has explored the genetic factors involved in the development of congenital heart defects, and her research sheds light on transcription factors and signaling molecules that play crucial roles in cardiac development. She has participated in large-scale studies examining low atrial rhythm in children. Dr. Lazea evaluated circulating chitotriosidase activity in children with obesity, providing insights into potential biomarkers related to metabolic health. She also collaborated on research investigating anatomical-MRI correlations in both adults and children with hypertrophic cardiomyopathy.
