The problems of arrhythmia are relevant, since arrhythmia is a syndrome that is often encountered in the practice of a doctor of any specialty and is one of the main causes of sudden cardiac death. From 28.10. to 01.11.24. in order to implement the academic mobility program, MD, Professor, Director of the Heart Rhythm Research Institute Abdrakhmanov Ayan Suleimenovich held master classes for cardiology residents, interns, and the teaching staff of the Department of Therapy, as well as lectures on topical issues of arrhythmology. At the University Hospital of the NAO “Semey Medical University”, the Emergency Hospital of Semey, Abdrakhmanov A.S. performed complex surgical interventions, such as implantation of a pacemaker using the LBBAP method, catheter ablation of additional conduction pathways, as well as catheter ablation for frequent ventricular extrasystoles. The Department of Therapy expresses its deep gratitude to Professor Abdrakhmanov A.S. for organizing academic mobility and providing the opportunity to exchange teaching experience and hopes for further cooperation!
