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.

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.

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.
