lead impeadence - Correct answer-...
sudden cardiac death - Correct answer-unexpected death from cardiac causes, producing abrupt loss of
cardiac output and cerebral blood flow. often death occurs >1 hr after symptoms. asystole or VF
Ischemic cardiomyopathy - Correct answer-Loss of muscle function due to hypoxia ( decreased 02 and
thus decreased blood supply) , but may have adequate ventricular filling, but decrease cardiac output.
Caused by CAD that narrows the small blood vessels that supply blood to the heart. Leads to Heart
Failure.
Cardiomyopathy - Correct answer-(literally "heart muscle disease") is the measurable deterioration of
the function of the myocardium (the heart muscle) for any reason, usually leading to heart failure;
common symptoms are dyspnea (breathlessness) and peripheral edema (swelling of the legs). People
with cardiomyopathy are often at risk of dangerous forms of irregular heart beat and sudden cardiac
death. The most common form of cardiomyopathy is dilated cardiomyopathy.
Hypertrophic Cardiomyopathy - Correct answer-Decreased compliance of the left ventricle and
hypertrophy of the ventricular muscle mass which impairs ventricle filling
Left vent. Thickening. Sx: faint, skipped beats, palp, dizzy, dyspnea, fatigue on exertion, sudden death.
, Increases thickness of left ventricular wall and septum, interferes with ejection of blood to aorta, early
warning sign = angina (heart pain) or death
TX: septal ablation, ICD, pacer, meds
CHADS 2 - Correct answer-CHF, HTN, age>75, DM2, stroke/tia
each one point, stroke=2pts
Score> 2= A.C.T.
CHADS 2 vasc - Correct answer-CHF, HTN, Age>75 (2pts), Age 65-74, Diabetes, Stroke/TIA (2 points),
vascular disease, Female
One point- Moderate risk, TX w/ A.C.T (anti-coagulation therapy) or asprin
neuro cardiogenic syncope - Correct answer-vaso vagal, or syncope w decrease HR and BP
First degree Heart block - Correct answer-long PR interval, > 20s, one large box
Primary Prevention - Correct answer-At risk WITH OUT history of event
Secondary Prevention - Correct answer-history of known even or disorder
Incidence - Correct answer-# of new cases per year
Prevalence - Correct answer-# of those diagnosed
Afterload - Correct answer-the tension or stress developev in the wall of the LV during ejection.
- The load the heart must eject blood aganist.
Preload - Correct answer-the initial stretching prior to contraction
Affected by ventricular end diastolic volume. higher end diastolic volume imples higher _______
