◉ reading EKG HR. Answer: -multiple QRS x 10 for broad estimation
-more precise:Divide 300 by the number of Large Boxes + .2 for each
small box.The above heart rate = 4 large boxes + 3 small boxes '0.6'=
4.6300/4.6= 65.2 Heart Rate is 65


◉ systolic heart failure. Answer: -inability of the heart to pump
sufficiently because of an alteration in the ability of the heart to
contract; term used to describe a type of heart failure
- decreased EF
-dilated, hypertrophied
-increased afterload
