He was then escorted to the ER across the street. He had a CT angiogram showing no pulmonary embolism. He received adenosine with no improvement followed by verapamil. He was admitted for further monitoring. He was ultimately electrically cardioverted back to normal sinus rhythm and discharged on metoprolol without a definitive diagnosis.
