Atrial Flutter With 2:1 Conduction

Fri, 10/04/2013 - 23:07 -- Dawn

Unfortunately, we have no clinical information on this patient, not even age or gender, as the ECG machine defaults to "Age 60".  The rhythm is a supraventricular tachycardia at a rate of about 260/min. with 2:1 conduction, resulting in a heart rate of about 130 / minute.  Some would call this atrial tachycardia, and some atrial flutter.  Since the reentrant pathways involved in the two rhythms are different, it is probable that an electrophysiologist could determine the exact location of the pathway in the EP lab.  Without benefit of this test, we use our best guess.
