Tag: How do you classify atrial flutter?

When atrial flutter is conducted 2:1, the resulting ventricular rate is around 125-175 per minute (usually around 150) . This is because the P waves (flutter waves) in atrial flutter occur at about 250-350 per minute (usually around 300).

Similar to atrial fibrillation, atrial flutter can be classified into the following types:

Type I atrial flutter, also known as common atrial flutter or typical atrial flutter, has an atrial rate of 240 to 340 beats/minute . However, this rate may be slowed by antiarrhythmic agents.
