Atrial dissociation in a middle aged patient: a case report

Acta Med Iran. 2014;52(8):641-3.


Atrial dissociation is characterized by different types of P waves captured in an electrocardiogram, usually seen in critically ill or post-cardiac transplantation patients. Our case demonstrates a 55-year-old man, presenting with chest pain (unstable angina) in the emergency department with transient double-P waves; representing the phenomenon. Our case did not have any of the suggested causes or any known cardiac problems; therefore, with ruling out other differential diagnosis, researches must be done to find another explanation, if repeated.
