Echocardiography plays a key role in planning and guidance of electrophysiological procedures. After exclusion of structural heart disease, echocardiography provides insight into the extent of left atrial remodeling by determining left atrial metrics. This "biomarker" is associated with the risk of new-onset atrial fibrillation and predictive of atrial fibrillation recurrence after ablation. Transesophageal echocardiography is necessary to exclude left atrial thrombi and is able to guide a transseptal puncture. In case of a rare but life-threatening cardiac tamponade, an echocardiographic-guided pericardiocentesis ensures quick and effective treatment. Left ventricular ejection fraction and deformation analysis determined by echocardiography are established methods for risk stratification in patients with systolic dysfunction and used to guide pharmacological and device therapy.
超声心动图在电生理手术的规划和引导中起着关键作用。在排除结构性心脏病后，超声心动图通过测定左心房指标来深入了解左心房重构的程度。这种“生物标志物”与新发房颤的风险相关，并可预测消融术后房颤的复发。经食管超声心动图对于排除左心房血栓是必要的，并且能够引导经房间隔穿刺。在罕见但危及生命的心脏压塞情况下，超声心动图引导下的心包穿刺术可确保快速有效的治疗。超声心动图测定的左心室射血分数和变形分析是收缩功能障碍患者风险分层的既定方法，并用于指导药物治疗和器械治疗。
