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.

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.

Read moreWhat is a typical atrial flutter?
Typical atrial flutter is an organised atrial tachycardia . It can also be defined as a macroreentrant tachycardia confined to the right atrium. This arrhythmia has a 200-260 ms cycle length, although it may fluctuate depending on patient’s previous treatment or ablation, congenital heart disease, etc.

Type II atrial flutter (AFII) is an arrhythmia which usually cannot be interrupted by atrial pacing : the underlying mechanism is considered to be a leading circle without an excitable gap.
