Exam 3 Flashcards
Other possible causes of chest pain
Pulmonary, GI, musculoskeletal, neurologic, psychogenic, idiopathic
Acute chest pain causes other than MI
GERD, peptic ulcer, gallstones, ischemic heart disease, pericarditis, pleuritis, pneumonia, pulmonary embolism, lung cancer, aortic aneurysm, aortic stenosis
Aggravating factors for angina
Eating, physical activity, smoking, cold weather, stress, anger, hunger, lying dow
Pericarditis
Substernal pain may radiate to neck and/or left arm
Sharp and may be accompanied by friction rub
Aggravated by deep breathing or supine postion
Alleviated by sitting up, leaning forward, anti-inflammatories
Dissecting aortic aneurysm
Retrosternal, upper abdominal, or epigastric pain
Excruciating and tearing pain
Costochondritis
Chest wall syndrome
Sharp, continuous or gradual pain; chest tender to touch
Aggravated by movement of palpation
Alleviated by time, analgesics, heat
Mitral regurgitation murmur
High pitched systolic murmur, heard best at the apex
Radiates to back or clavicle
Prone to CHF
S/S: SOB, pulmonary edema, orthopnea, decreased exercise intolerance, palpitations, A Fib
Mitral valve prolapse
Mild to late systolic click and late systolic murmur
Gets louder when patient stands up
Harmless in most cases
Mitral stenosis
Holodiastolic murmur
Low pitched
S/S: may begin with A fib, cough, difficuty breathig, fatigue, ankle edema
Aortic regurgitation
Diastolic murmur
High pitched
Best heard when sitting forward
S/S: SOB, CHF, palpitations,
Aortic stenosis
Systolic murmur
Louder with squatting
S/S: SOB with activity, angina, dizziness, palpitations
Pulmonic regurgitation
Diastolic murmur
S/S: right heart failure
Tricuspid regurgitation
High pitched systolic murmur
Tricuspid stenosis
Mid-diastolic murmur
Louder with exercise and inspiration
Softer with standing
Pulmonic stenosis
Systolic murmur
Sound radiates to neck or back
Deep inspiration will intensify the murmur
Inspiration augments which murmurs
Right sided sounds due to increased venous return
-Tricuspid and pulmonic stenosis
Vasalva maneuver augments which murmurs
Mitral stenosis, mitral valve prolapse
Squatting augments which murmurs
Aortic regurgitation, aortic stenosis, mitral regurgitation, mitral stenosis
MSARD
Mitral stenosis, aortic regurgitation
DIASTOLIC
MRASS
Mitral regurgitation, aortic stenosis
SYSTOLIC
Cardiac conduction
Starts in SA node to the AV node to bundle of His and then out to bundle branches and out to Purkinje fibers
Normal PR interval
0.12-0.2
Normal QRS
0.08-0.1
Normal QT
0.4-0.43
Premature Atrial Contraction
Rhythm regular
P wave premature or hidden
PR interval <0.2
QRS <0.12
Supraventricular tachycardia
Sudden start and stop
170-250 bpm
Atrial Flutter
Atrial HR 220-430
Rhythm regular
QRS <0.12
A Fib
Atrial HR 350-650
Irregular rhythm
No discernable P waves
V Tach
Symptomatic when sustained v tACH
1st degree AV block
Regular rhythm
One P wave to each QRS
OR prolonged
QRS normal
2nd degree AV block
Type 1
Rhythm regular
PR progressively lengthens until P wave occurs without QRS
2nd degree AV block
Type 2
PR interval constant but there is failure to conduct in the bundle of his and purkinje systems
QRS is dropped and wide
Pacemaker needed
3rd degree AV block
No impulses conducted from atria to ventricles
P waves marching through rhythm strip
Atrial rate 60-80, ventricle rate of 20-40
Pacemaker needed
Cor pulmonale
Enlargement of right ventricle secondary to pulmonary malfunction
Tetralogy of fallot
Ventricular septal defect
Pulmonic stenosis
Dextroposition of the aorta
R. Ventricular hypertrophy
Acute rheumatic fever
Systemic connective tissue disease occurring after streptococcal pharyngitis or skin infection
Kawasaki disease
Condition causing inflammation in walls of small and medium arteries throughout the body
S/S A fib
Palpitations, lightheadedness, fatigue, poor exercise capacity, angina, dypnea, syncope
Labs for MI
Troponin 1 and T increased 3-6 hours after onset and peaks at 12-24 hours, remaining elevated for 2-3 days
Myoglobin is early marker for myocardial necrosis which peaks at 1-4 hours
Levine’s sign
Clenched fist over center of chest
Dx labs for familial hypercholesterolemia
Severely high LDL >330, mildly elevated triglycerides, HDL normal or low
Giant cell arteritis/temporal arteritis
Headache, painless blindness without any visual changes to the eye, jaw claudication, scalp tenderness
Endocarditis
Fever, chills, cough, dyspea, night sweats, weight loss
May have signs of HF, splinter hemorrhages in nail beds, conjunctival petechiae, splenomegaly, retinal hemorrhage
