irregular rhythms, not as accurate for regular
Q12: 300 method
A: count the number of large boxes between the 2 R waves and divide this number INTO 300 to obtain the HR Ex. 5
boxes. 300/5 = 60 BPM
Q13: 1500 method
A: count the number of small boxes between two R waves and divide this number into 1500 to obtain the HR
Q14: ventricular tachycardia
A: -often monomorphic and appears regular -rate between 110-250 bpm -VT exists if 3 or more consecutive PVCs are
present at a rate of >100 bpm
