Bicuspid or Mitral Valve
The AV valves open during the heart’s filling phase, or diastole, to allow the ventricles to fill with blood.
What is the first heart sound? When does it occur and what does it signal?
The first heart sound (S1) "LUB" occurs with closure of the AV valves and thus signals the beginning of systole.
What numbers make up the QRS complex and what does it mean?
#2,4,3=QRS complex—Depolarization of the ventricles
What is Mitral regurgitation?
mitral insufficiency; an incompetent mitral valve allows regurgitation of blood back into the left atrium during systole

Where are the Semilunar valves found? What are their names and where are they located?
Semilunar (SL) valves are set between the ventricles and the arteries.
The SL valves are the pulmonic valve in the right side of the heart and the
aortic valve in the left side of the heart.
What is the second heart sound? When does it occur and what does it signal?
The second heart sound (S2) "Dub" occurs with closure of the semilunar valves and signals the end of systole.
What does the timing of the Carotid Artery Pulse coincide with?
Its timing closely coincides with ventricular systole or (S1).
What is left ventricular hypertrophy (LVH) & when does it occur?
Left ventricular hypertrophy (LVH) increase in thickness of the myocardial wall that occurs when the heart pumps against chronic outflow obstruction (e.g., aortic stenosis)
What is Coarctation of Aorta?
It is a severe narrowing of the descending aorta, a congenital heart defect.

Contraindicated with Electrolyte imbalances.
The valves’ thin leaflets are anchored by collagenous fibers to papillary muscles embedded in the ventricle floor. What are those fibers called?
Chordae Tendineae
Describe what happens during Diastole?
In diastole the ventricles are relaxed, and the AV valves (i.e., the tricuspid and mitral) are open The pressure in the atria is higher than that in the ventricles; therefore blood pours rapidly into the ventricles. Toward the end of diastole the atria contract and push the last amount of blood (about 25% of stroke volume) into the ventricles. This active filling phase is called presystole, or atrial systole, or sometimes the atrial kick. It causes a small rise in left ventricular pressure. (Note that atrial systole occurs during ventricular diastole, a confusing but important point.)
Name all four characteristics of all heart sounds. (how would you describe heart sounds)
1. Frequency (pitch)
2. Intensity (loudness)
3. Duration
4.Timing
Explain Paradoxical splitting.
Opposite of a normal split S2, so that the split is heard in expiration, and in inspiration, the sounds fuse into one sound.
What is Aortic Stenosis, and what does it do?
Aortic stenosis is the calcification of the aortic valve cusps that restricts forward flow of blood during systole.
What is the pharmacological class of Lisinopril, what is it used for, and who is it contraindicated in?
ACE inhibitor/Angiotensin Converting Enzyme
Used for (CHF) Chronic Heart Failure, and Hypertension.
Contraindicated in Pregnancy.
Name the correct direction of blood flow through the heart.
Right atrium, right ventricle, pulmonary artery, lungs, pulmonary vein, left atrium, left ventricle
Describe what happens during Systole?
Now so much blood has been pumped into the ventricles that ventricular pressure is finally higher than that in the atria; thus the mitral and tricuspid valves swing shut. The closure of the AV valves contributes to the first heart sound (S1) and signals the beginning of systole. The AV valves close to prevent any regurgitation of blood back up into the atria during contraction. After the ventricle’s contents are ejected, its pressure falls. When pressure falls below pressure in the aorta, some blood flows backward toward the ventricle, causing the aortic valve to swing shut. This closure of the semilunar valves causes the second heart sound (S2) and signals the end of systole.
Describe Preload & Afterload.
Preload is volume—it is the venous return that builds during diastole.
Afterload is pressure—it is the opposing pressure the ventricle must generate to open the aortic valve against the higher aortic pressure.
Explain Pulmonic regurgitation?
Pulmonic insufficiency; backflow of blood through incompetent pulmonic valve into the right ventricle.
What is Aortic Regurgitation & what does it do?
It is (aortic insufficiency) an incompetent aortic valve that allows backward flow of blood into the left ventricle during diastole.
