Key result
Bipolar atrial wire electrode recordings in 27 post-cardiac surgery patients identified two distinct types of atrial flutter: type I (240-338 beats/min) and type II (340-433 beats/min).

What are the electrophysiological characteristics that differentiate types of atrial flutter in patients after open heart surgery?
This study identifies and characterizes two distinct types of atrial flutter (Type I and Type II) based on atrial rate and response to rapid atrial pacing.
Wells et al. (1979) conducted an observational in Atrial flutter after open heart surgery (n=27). Bipolar atrial wire electrodes for recording and pacing was evaluated on Characterization of atrial flutter types. Bipolar atrial wire electrode recordings in 27 post-cardiac surgery patients identified two distinct types of atrial flutter: type I (240-338 beats/min) and type II (340-433 beats/min).
