How to calculate ventricular rate in atrial flutter. Theoretically its far easier to figure out the ventricular rate and then just double it if you know its a 21. The first treatment goal for atrial flutter is to control the ventricular rate. One quick and easy way to measure the ventricular rate is to examine the rr interval that is the distance between two consecutive r waves and use a standard scale to find the rate.
If you experience serious symptoms such as chest pain or congestive heart failure related to the ventricular rate. Edit again f. This ventricular rate is determined by the refractory period of a healthy av node such that every other impulse 21 traverses the av node and travels to the ventricles.
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.
