Question 29

How do you obtain Atrial Rate Ventricular Rate

Answer 29

Atrial Rate: Count the number of P waves (6 sec strips) and multiply that number by 10. Ex. 7 pwaves (6sec) x 10 = HR 70 beat/min Ventricular Rate: Count the number of QRS Complexes (6 sec strips) and multiply that number by 10. Ex. 7 QRS Complexes (6sec) x 10 = HR 70 beat/min

P Wave represents the depolarization occurring in the Atria QRS Complex represents the depolarization occuring in the Ventricles
