sinoatrial node/SA node

what is happening during the P-Wave

atrial depolarization

what happens during the QRS complex

ventricular depolarization

what happens during t-wave

ventricular repolarization

what is tachycardia

resting heartrate over 100 bpm

what is bradycardia

heartrate below 60 bpm

what is fibrillation

irregular heart beat, atria quiver instead of contract

what is systolic pressure

pressure of blood vessels when left ventricle contracts

what is diastolic pressure

pressure of blood vessel walls when left ventricle relaxes

how do you calculate pulse pressure

systolic - diastolic

how do you calculate mean arterial pressure

((Diastole x 2) + systolic) / 3

how to calculate heart rate given the cardiac cycle length

60 / cardiac cycle length

how to calculate heart rate given EKG line

300 / number of big boxes between r to r

what is the heartrate (round up) (9 small squares)

167

what is the heart rate (round up) (12 small squares)

125

what is the heartrate (19.5 small squares) (round up)

77

what is the heartrate (round up) (20 small squares)

75

what is the heartrate if the cardiac cycle is .8 seconds

75

what is the heartrate if the cardiac cycle is .6

100

what is the heartrate if the cardiac cycle is .5

85

what is the pulse pressure of someone with a bp of 130/70

60

what is the pulse pressure of someone with a bp of 150/97

53
