What is atrial fibrillation with rapid vent. response?

Does it just simply mean a heart rate greater than a 100 with atrial fibrillation?
If a pt is in afib and the heart rate is 67 than it wouldn't be a rapid vent response....because the ventricles aren't responding rapidly right?

Atrial fibrillation means the atria are just quivering and not really contracting & relaxing and squirting blood into the ventricles (atrial kick). This is due to defective conduction through the sinoatrial node (SA). Instead of organized conduction; there is a disorganized, chaotic electrical discharge through out the atria. Because the electrical charge is not conducted normally, ventricular response can be slow or fast depending on the contraction rate of the ventricles/minute. In atrial fibrillation and flutter, the atria are stimulated to contract very quickly and differently from the normal activity originating from the sinoatrial node. This results in ineffective and uncoordinated contraction of the atria in atrial fibrillation, and in a peculiarly organized contraction pattern in atrial flutter.

The condition can be caused by impulses which are transmitted to the ventricles in an irregular fashion or by some impulses failing to be transmitted. This makes the ventricles beat irregularly, which leads to an irregular (and usually fast) pulse in atrial fibrillation.The organization of the atria to ventricle contraction is also disorganized

the atrial rate cannot be measured because it is so chaotic, usually >350 bpm. but ventricular rate is much slower because the AV node blocks most of the impulse. if the ventricular rate is less than 100 then it is considered "controlled". if it is over 100 per minute, it is considered "rapid ventricular response"

Atrial fibrillation is a condition in which the heart's electrical system has gone haywire and operates erratically and not according to standard pumping EKG curves for both ventricles.

Rapid Atrial fibrillation is a "high speed " heart where the heart is going so fast, usually over 120 Beats minute that it literally destroys itself.

Just because you have a 67 beats minute heart at this moment doenst mean you dont have a "high speed heart" and Rapid Vent. response.

That Rapid Vent response can occur for no apparent reason and those people who have that condition are immediately rushed to Emergency where Electric shock treatment and anti Atrial Fib drugs are intravenously injected to elevate the condition and save the persons life.

The Cleveland Clinic a really good source for info on Atrial Fib. Go to the Cleveland Clinic Site and it explains this fully.

You are correct!
