Webb19 juli 2024 · The ventricular rate in atrial flutter is principally determined by the rate at which impulses exit the atrioventricular (AV) node. With a regular atrial rate of 300 beats/min, the ventricular rate is usually about 150 beats/min. Webb21 sep. 2024 · There are several methods for determining the ventricular rate or heart rate. Below, I share three of them. Method #1: Identify an R-wave that is on a line. Use that as the start R-wave and then count success big boxes from the start as 300, 150, 100, 75, 60, 50. Below 50, use the formula given in method #2. This method is good for regular rhythms.
