A classification of atrial flutter and regular atrial tachycardia according to electrophysiological mechanisms and anatomical bases. A Statement from a Joint Expert Group from the Working Group of Arrhythmias of the European Society of Cardiology and the North American Society of Pacing and Electrophysiology

Key Points

• This research aims to classify atrial flutter and regular atrial tachycardia based on their underlying electrophysiological mechanisms and anatomical origins.
• Joint expert group discussion
• Review of electrophysiological and anatomical features
• Consensus statement development
• Presented a comprehensive classification system for atrial flutter and tachycardia.
• Identified distinct electrophysiological mechanisms associated with each type.
• Suggested new pathways for diagnosis and treatment based on anatomical considerations.
