Pace Maker of the Heart -Answer The Sino Atrial node is also known as the
100/60 -138/89 -Answer Normal BP range is
-0.1 eV for each box in the vertical direction
-typically there are 10 boxes in the vertical direction for QRS complexes, adding up to
1.0 eV -Answer The vertical lines in each of the boxes indicate:
Coreg and epinephrine -Answer What medication can change Atrial fibrillation to a
sinus rhythm?
140-250 bpm -Answer What is the heart rate with a SVT?
-Stimulate the sympathetic nervous system, which is a division of the somatic nervous
system
-increase the heart rate
-increase blood supply to the brain, heart, lungs and kidney
-cause the pupils to dilate -Answer Medications such as epinephrine and adrenaline do
what?
Count the small boxes between two regular R peaks and divide them into 1500 -Answer
There are several ways to calculate a heart rate, however the most exact method
entails:
P wave -Answer Atrial depolarization and activation causes which wave to emerge after
the resting phase?
digoxin -Answer Which of the medications is used to treat CHF, and can also cause
hypokalemia?
QRS = 0.08-0.12 sec
PR = 0.12-0.20 sec
QT = 0.36 - 0.44 sec -Answer What are the measurements of QRS, PR, and QT?
beat slower -Answer The parasympathetic nervous systems causes the heart to .....
slower -Answer With respect to a heart rhythm that contains the P,Q, R, S and T wave,
the wider the QRS the _____________________ the heart rate.
heart block -Answer Damage to the AV node, essentially the entire conduction system
is blocked and the ventricles must resort to contracting at an intrinsic rate which is a
much slower rate.
