The electrocardiogram and various echocardiography modalities are important risk markers for atrial fibrillation (AF). Electrocardiographic criteria of left atrial enlargement, advanced interatrial block, and PR-interval prolongation are atrial risk markers for AF. Transthoracic echocardiography is elementary for risk stratification of AF. Transesophageal echocardiography is a valuable tool to detect cardiac sources of embolism if early cardioversion is necessary. Intracardiac echocardiography is a real-time tool for guidance of percutaneous interventions, including radiofrequency ablation and left atrial appendage closure in patients with AF.
