Tachycardia - 🧠ANSWER ✔✔abnormally rapid heart rate - above 100
Bradycardia - 🧠ANSWER ✔✔abnormally slow heart rate - under 60
preload - 🧠ANSWER ✔✔volume of blood in ventricles at end of diastole
Afterload - 🧠ANSWER ✔✔resistance against which left ventricle pushes
blood out
Systole - 🧠ANSWER ✔✔contraction of heart .... provides increase in
pressure to eject blood
Diastole - 🧠ANSWER ✔✔relaxation of heart.... required for filling chambers
,When is preload increased? - 🧠ANSWER ✔✔hypervolemia, regurgitation of
cardiac valves, heart failure
When is afterload increased? - 🧠ANSWER ✔✔hypertension,
vasoconstriction
What increases when afterload increases? - 🧠ANSWER ✔✔increase in
cardiac workload
What is cardiac output? - 🧠ANSWER ✔✔Volume of blood ejected by the
heart in one minute:
cardiac output = heart rate x stroke volume
What is stroke volume? - 🧠ANSWER ✔✔Volume of blood pumped out of
ventricle- contraction
The heart sound, lubb is due to the _________ . - 🧠ANSWER ✔✔closure of
AV valves
The heart sound, dub is due to the ________. - 🧠ANSWER ✔✔closure of
semilunar valves.
pulse rate - 🧠ANSWER ✔✔heart rate 60-100 bpm.
, What do vasodilators do? - 🧠ANSWER ✔✔dilates (opens) blood vessels,
which allows blood to flow more easily
example: nitroglycerin
What do beta blockers do? - 🧠ANSWER ✔✔-decrease heart rate and blood
pressure
-treat HTN & dysrhythmias
-reduce angina attacks
arteriosclerosis - 🧠ANSWER ✔✔hardening of blood vessels
Atherosclerosis - 🧠ANSWER ✔✔plaque build up in the coronary artery
causing clots, often leads to MI.
Diuretics - 🧠ANSWER ✔✔medications administered to increase urine
secretion in order to remove excess sodium and/or water.
- treats high blood pressure and congestive heart failure
anticoagulant - 🧠ANSWER ✔✔a drug that prevents clotting of the blood
low-density lipoprotein (LDL) - 🧠ANSWER ✔✔Transports cholesterol from
liver to cells
