Trace that Path
# of times blood passes through the heart in each cardiac cycle
What is two?
Initial problem: LV myocardium grows too large, decreasing space for blood
What is cardiomyopathy?
Type of BV that relies on voluntary muscle to help move blood
What is veins?
What are the layers of the heart in order from inside to outside?
What is endocardium, myocardium, and epicardium?
Chest pressure, radiating pain, nausea, dyspnea, weakness
What is MI?
Valve that leads out of the heart the first time in each cardiac cycle
What is the pulmonic valve?
Disease where Coronary arteries harden, then lose elasticity and function. Can be d/t plaque buildup or hardening.
What is CAD?
Largest veins of the body
What is the IVC & SVC?
What ability do heart muscle cells have that no other cell in the body have
What is automaticity/autorhythmic ability?
Palpitations, weakness, cough, peripheral edema, weight gain, abd swelling
What is valve disease?
Chamber with the thickest myocardium
What is the left ventricle?
Disease that increases the risk for CVA, MI, or PE
What is DVT?
Site of gas exchange from blood to cells
What is Capillaries?
Name the coronary arteries
What is the right coronary artery, the left coronary artery, the circumflex, and left anterior descending artery?
Dizziness, confusion, facial drooping, hemiparesis, dysphagia
What is CVA?
Chamber to receive blood BEFORE the Tricuspid valve
What is the Right Atrium?
Disease that causes regurgitation in the lungs d/t loss of heart's ability to pump
What is Left-sided CHF?
2 BV that act as funnels
What are arterioles and venules?
Name the 3 types of circulation
What is Coronary, Systemic and Pulmonary?
Headache, dizziness, nosebleed, blurred vision, fatigue, or no S/S at all
What is HTN?
Name the chambers and valves in order blood passes through them
What is the RA, Tricuspid valve, RV, Pulmonic valve, LA, Mitral valve, LV, Aortic valve?
Name at least 8 s/s of MI
What is decreased LOC, neck pain, jaw pain, feelings of impending doom, N/V, weakness, chest pressure, angina pectoris, radiating pain, diaphoresis, dyspnea, and indigestion?
Name 3 characteristics of arteries, veins and capillaries
What is arteries are the thickest, most flexible, can withstand the pressure of the heart, pump blood away from the heart, veins are thinner, we draw blood from them, they rely on voluntary muscle to help move blood, they return blood to heart, they have one-way valves, capillaries are the site of gas exchange, one cell thick, smallest BV, look like fishnets?
Describe the treatment for MI starting with identification through ER orders
What is identify S/S, call 911, give aspirin, in ER MD will order 12 lead EKG and Troponin level?
SUDDEN severe angina pectoris, feelings of impending doom, dyspnea, cyanosis
What is PE?
