Cardiac Stunning After Electrical Cardioversion

Active, not recruiting

Brief Summary: The goal of this observational study is to evaluate cardiac stunning and electrocardiographic parameters through transthoracic echocardiography and 24 hours ECG conducted immediately following electrical cardioversion. The main question it aims to answer is:

Do echocardiographic and electrocardiographic parameters relating to cardiac stunning predict atrial fibrillation (AF) recurrence rates after electrical cardioversion?

Participants will undergo echocardiography and a 24-hour Holter monitoring immediately after electrical cardioversion.
