Description: Notice the saw tooth waves between the QRS peaks.They appear even in Atrial Flutter.When you count the atrial beats, you need to count the number of tiny boxes between to flutter waves and divide them into 1500.So for this rhythm there are roughly 6 small boxes between two flutter waves.1500/6 = 250 This is the atrial rate.Notice that there are 3 waves to 1 QRS so this is a 3:1 If you measure the Ventricular rate you will notice that there are about 7.5 large boxes or36 small boxes,
