Dr. Henderson said what?
Part of the cardiac cycle when the AV valves close and the SL valves open.
What is systole?
Defined by:
slow growth
well-defined capsule
not invasive
well differentiated
low mitotic index
What is a benign tumor?
Stroke
cardiogenic shock
congestive heart failure
cardiac tamponade
arrhythmias
pericarditis
What are complications of myocardial infarctions?
Patients with this type of condition have problems getting air out.
What is Obstructive disorders?
A benign tumor in a patient's neck is causing dysphagia.
What is mass effect?
Blood passes through this valve on its way to systemic circulation.
What is the aortic valve?
Disorganized growth. Net increase in number of dividing cells.
What is neoplasia?
EKG shows T wave inversion. This lab result would be analyzed in order to diagnose MI.
What is troponin?
Elevated RBCs. Could lead to blood clots.
What is polycythemia?
A patient with small-cell carcinoma of the lung is experiencing SIADH.
What is paraneoplastic syndrome?
The amount of filling of ventricles before the heart contracts.
What is preload?
Encode proteins that, in their normal state, negatively regulate proliferation. AKA "anti-oncogenes"
What are tumor-suppressor genes?
Decreased ability to pump. Left ventricle loses its ability to generate enough pressure to eject blood forward through the aorta, resulting in decreased ejection fraction.
What is Systolic Heart Failure?
Pulmonary Fibrosis
Sarcoidosis
Pneumoconiosis
What are intrinsic restrictive lung diseases?
You notice elevated ST segments on an EKG for a patient having chest pain.
What is a STEMI?
Increased ventricular stretch leads to greater contraction force and increased stroke volume.
What is the Frank-Starling Law?
What is angiogenesis?
Mitral Stenosis
Tricuspid Stenosis
Aortic Regurgitation
Pulmonic Regurgitation
What are diastolic murmurs?
The amount of air a person can forcefully exhale in one second.
What is FEV1?
Blood backs up in the right atrium. RVEDV increases. RVESV normal initially, and then increases. Manifests as fatigue, SOB.
What is tricuspid regurgitation.
Lipoprotein secreted by type II cells that reduces surface tension and decreases work of inflation.
What is surfactant?
An example of a tumor suppressor gene. Known as the "guardian of the genome." Repairs DNA. Halts the cell cycle.
What is P53?
Late diastolic, low-pitched sound. Suggests poor diastolic function. Occurs from atrial kick squeezing blood into stiff ventricle.
What is S4?
Characterized by hypercapnia, hypoxemia, impaired diffusion, and V/Q mismatches.
What is acute respiratory failure?
FEV1 and FVC are equally impaired, but the ratio is normal. Decreased inspiratory residual volume and inspiratory capacity.
