It occurs in varied situations but lightning induced AF is extremely rare. Here is a case which reverted to sinus rhythm spontaneously. This 37-year-old man without any underlying heart disease had new onset AF after being struck by a lightning. Oral Metoprolol alone was given to control ventricular rate. Spontaneous reversion to sinus rhythm within 36 hours is in favor of new onset lightning induced AF. Key words: Lightning injuries, atrial fibrillation, ECG changesen-USArticle
