MS CAD
Independent Study
| Term | Definition |
|---|---|
| pericarditis | inflammation of the pericardium (sac around heart mm) can be acute or chronic |
| classic symptom of pericarditis | sharp & often sudden pleuritic pn that increases w/ deep inspiration |
| endocarditis | also known as infective endocarditis. is inflammation of the membrane lining the valves & chambers of the heart. can be acute, subacute or chronic |
| most common valve problems | mitral & aortic |
| location of mitral valve | between L ventricle & L atrium |
| location of aortic valve | between L ventricle and aorta |
| mitral stenosis | blood flow is obstructed from L atrium to L ventrical-valve opening too narrow |
| insufficiency | blood from L ventricle flows back into L atrium-backflow |
| prolapse | "to fall out of place"- valves don't close properly |
| 2 types of valve sx | balloon valvuloplasty or surgical replacement of valve |
| cardiomyopathy | group of conditions that affect the heart mm. the only cure is a heart transplant |
| congenital heart disease | anatomic defect that develops in utero |
| 2 categories of congenital heart disease | cyanotic & acyanotic |
| cyanotic conditions | blood flow obstructed or oxygenated blood being mixed with venous blood |
| arrhythmia | disturbance in heart rate or rhythm caused by SA node dysfunction or conduction disturbance |
| bradycardia | <60 BPM |
| tachycardia | >100 BPM |
| atrial fibrillation | involuntary, irregular mm contraction of atrium, most common arrhythmia |
| ventricular fibrillation | involuntary mm contraction of ventricles (frequent cause of cardiac arrest) |
| heart block | conduction block from SA node to rest of heart |
| Dx of arrhythmia | EKG, Holter moniter: EKG x 24 hrs + pt keeps diary of activity & symptoms |
| Rx of arrhythmia | antiarrythmic meds, cardioversion, artificial pacemaker (post pacemaker sx: no lifting > 10 lbs x 6 wks. Estim & US in area are contraindicated) |
