Disorders of cardiac rhythm in China

The Annual Report on Cardiovascular Health and Diseases in China (2022) intricate landscape of cardiovascular health in China. In connection with the previous section, this seventh section of the report offers a comprehensive analysis of disorders of heart rhythm in China. In 2021, China has achieved significant development and gratifying results in many aspects of the field of arrhythmia. Left bundle branch pacing (LBBP), as an emerging pacing technique originating from China, has received widespread attention. New research results have emerged on its indications, surgical procedures, clinical evaluation, and comparison with other pacing techniques. Its feasibility, effectiveness, and safety have been basically verified, but its long-term prognosis still needs further confirmation from larger samples and longer follow-up time research results. Leadless pacemakers have begun to be used in a wider range of clinical applications, and related large sample cohort studies have been reported. In addition, there are also noteworthy new achievements in the fields of pacemaker remote programming, anticoagulation and radiofrequency catheter ablation (RFCA) therapy for atrial fibrillation, and implantable cardioverter defibrillator prevention of sudden cardiac death. In terms of clinical practice, due to COVID-19 pandemic, the number of RFCA procedures and other device implantations in China has fluctuated, but it has gradually recovered since 2020.
