This expert consensus statement of the European Heart Rhythm Association (EHRA), the Heart Rhythm Society (HRS), the Asia Pacific Heart Rhythm Society (APHRS), and the Latin American Heart Rhythm Society (LAHRS) is based on a thorough review of the medical literature regarding cognitive function in arrhythmias and is intended to describe the impact of different types of arrhythmias on cognitive function, to highlight possible risk markers for cognitive decline, and to formulate implications for clinical practice regarding follow-up methods, prevention, and treatment strategies. The objective is to raise awareness of cognitive function among physicians treating patients with arrhythmias and to provide them with practical proposals that may lead to improvement of patient care in this regard. 

The document reviews terminology and the epidemiology of cognitive dysfunction, methods for assessment of cognitive function, and the role of imaging and also provides an overview of the association of other arrhythmias and cognitive dysfunction, including settings such as postcardiac arrest, cardiac implantable devices, or ablation procedures. Implications for electrophysiological procedures and cognitive function are also discussed, and gaps in knowledge and areas for further research are highlighted.
