Symptoms of atrial fibrillation A normal heart rate, when you are resting, should be between 60 and 100 beats a minute . In atrial fibrillation, it may be over 140 beats a minute. If you notice an irregular heartbeat and/or have chest pain, see your doctor immediately.

4:1 block. High-grade AV block (4:1 conduction ratio) Atrial rate is approximately 140 bpm. Ventricular rate is approximately 35 bpm . See High Grade AV Block.
Read moreHow do you calculate atrial flutter ratio?
The degree of blocking in the atrioventricular node is specified by counting the number of flutter waves preceding each QRS complex . If 3 flutter waves occur before each QRS complex then it is 3:1 block. If there are 2 flutter waves before each QRS complex then it is 2:1 block.
Read moreWhat is a 2 1 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).15 Kas 2016

Read moreWhat is the criteria for atrial flutter?
Atrial flutter occurs when a “reentrant” circuit is present, causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute ; the atrial rate in atrial fibrillation is 400 to 600 bpm.
