Atrial Flutter With Variable Conduction

Wed, 08/07/2013 - 11:41 -- Dawn

This ECG, showing atrial flutter with variable conduction, has good teaching points for all levels of students.  The atrial rate is between 250 and 350 bpm, actually very close to 300 bpm, which is typical of atrial flutter.  The flutter waves create a "sawtooth" pattern in most leads, but not all.   One good teaching point, always evaluate an ECG in as many leads as possible and practical, since the signs you are looking for may not be very obvious in all leads.
