Cardio Flashcards
CHF
DOE
PND
edema
Echo w/ LVH or RVH
hypokinesis
CHF
dilated cardiomyopathy
pregnancy
S3
Hypertrophic CM or fatal arrhythmia, get EKG or echo
young athlete with syncope during athletic event or practice. No physical exam abnormalities
Atrial fibrillation (holiday heart)
alcoholic with palpitations, arrhythmia
Atrial fibrillation; (if >48 or chronic - anticoagulate)
irregularly irregular
Do exercise stress test
Hx angina but no acute sx. EKG no acute changes
Angina (if lasts minutes), AMI if lasts > 30 minutes. Acute ischemia - ST elevation; Injury - T wave depression; Infarct - Q wave
Crushing CP, dyspnea, palpitations, radiation to neck or left arm
Warfarin (2-3 for Afib; 2.5 - 3.5 for valve); Tx Warfarin OD is vitamin K
Atrial fibrillation or prosthetic valve
Pericarditis
Constant, sharp CP worse lying down, better sitting up and leaning forward
Pericardial effusion/tamponade (Beck’s triad)
JVD, Hypotension, muffled heart sounds
Aortic dissection
Sudden onset ripping, tearing chest pain, diminished pulses
AAA
Flank pain, hypotension, pulsatile abdominal mass
Digoxin toxicity (hypokalemia will make worse)
EKG changes, N/V, yellow-green visual disturbances
ACEI is cause
HTN tx w/ meds, cough, or angioedema
ACEI is best choice
DM and HTN
Think secondary HTN most likely Renal artery stenosis (infrarenal artery)
HTN not responsive to basic meds
Bacterial endocarditis (strep viridians) prevention
Mechanical valve or prosthesis and dental, GU, GI, or ortho procedure prophylaxis
Bacterial endocarditis (staph aureus, strep viridians)
IVDA w/ new murmur
Aortic stenosis (due to calcifications - age related) or bicuspid valve - congenital
Elderly w/ systolic murmur
Aortic stenosis
Diamond shaped, blowing systolic murmur. May have angina, syncope, CHF
Aortic regurgitation/insufficiency:
Quincke’s pulse (subungual capillar pulsation), Corrigan (rapid rise and fall), Austin flint (low pitch middiastolic murmur at apex)
Lateral displaced PMI, canon “a” waves, Quincke’s pulse, Corrigan’s pulse, Austin flint murmur, deMusset’s sign, water
Mitral stenosis (ARMS are BAD)
Diastolic murmur best heart at apex without radiation
Mitral valve prolapse
Female or post MI systolic murmur best at apex preceded by click without radiation
Mitral regurgitation
Systolic murmur heard best at apex with radiation to left axilla (apical systolic)
Mitral regurgitation (caused by papillary muscle rupture)
New murmur after MI (esp. if apical systolic)
PDA
Continuous harsh, machine-like murmur
VSD
Infant with dyspnea, difficulty feeding, holosystolic murmur @ LSB 3rd ICS. LVH and RVH
Hs and Ts
hypovolemia
hypoxia
Hypothermia
hydrogen ion (acidosis)
hyper-hypokalemia
hypoglycemia
tamponade cardiac
tension pneumo
thrombosis - PE or cardio
Toxins
Trauma
Pulseless electrical activity
Coarctation of aorta
Peds w/ leg pain after physical activity, abnormal heart sounds, unequal UE and LE pulses
Arterial insufficiency/PAD, intermittent claudication (ABI best choice, arteriogram gold standard)
Tx is arterial bypass
LE rubor, no hair, brittle nails, palloe on elevation, calf or LE pain esp. with walking short distances relieved with rest or at PM
Claudication with rest pain, (ABI < 0.4)
Varicose veins. Tx w/ compression stockings
LE pain after long periods of standing. Dilated, tortuous, veins
AS
Murmur that causes weak carotid pulse
Liver toxicity
Side effect of statin drugs
Cocaine
Illegal substance that causes MI secondary to acute coronary vasospasm
Infective endocarditis
Scaly plaques on palms and soles
Janeway lesions
Infective endocarditis
Tender nodules on tips of fingers and toes
Osler nodes
Volume of blood in ventricles at the end of diastole
Pre-load
Amount of blood being pumped out of the L ventricle during contraction
Ejection fraction
Aortic dissection
Tearing, ripping pain between scapula
Widened mediastinum
CXR with aortic dissection
Coarctation of the aorta
BP higher in arms than the legs
300-150-100-75-60-50
EKG - rate assessment
First degree AV block
PR interval greater than 0.2 sec consistently in every cycle
Wenchebach
Second degree AV block
PR interval gradually lengthens in successive cycles , last P wave fails to conduct ventricles
Complete third degree AV block
AV block in which there is a total block of conduction to the ventricles so no atrial depolarizations are conducted to ventricles
Mobitz and Wenchebach
Types of second degree AV blocks
Confirm in a second lead
asystole
