Cardiovascular Flashcards
Malignant hypertension
Diastolic bp >140
Associated w/ retinal hemmorhaging and papilledema
Accelerated hypertension
Diastolic bp >120
Associated w/retinal hemmorhaging
Hypertensive crisis 3 types
Essential
Accelerated
Malignant
Treatment of hypertensive crisis
Vasodilator and sympathetic blocking agents
Cardiomyopathy 3 types
Dilated
Hypertrophic
Restrictive cardiomyopathy
Hypertrophic cardiomyopathy aka
Hypertrophic obstructed cardiomyopathy
Idiopathic hypertrophic subaortic stenosis
Ihss has a big
Fat vent. Septum
Hypertrophic cardiomyopathy treated w/
Beta or ca channel blockers
In hcm or Ihss don’t give
Digoxin nitrates dope amine isuprel morphine

Pawp indicates
Left atrial pressure/lvedp
Pawp made of____waves
A atrial contract
C m valve closing
V. Atrial filling

Pawp elevated in
Left sided heart dysfunction
Pad correlates w/
Lvedp and pawp
Pawp correlates w/
Lvedp and pad
The pawp shouldn’t be____than pad
Higher
Pa catheters must be in zone ___to be accurate

How do I know pa cath is in zone I or II?
Pawp>pad
Pawp>pad
Absence of a&tv waves
Marked resp variations
Any peep >____effects pawp reading

Peep>10. Calc true pawp
Peep/1.36. /2. Then subtract result from pawp
2 causes of murmurs
Forward flow blood stenoic open valves
Back flow blood through incompletely closed valves

Leads v1 v2 v3 have a ___wave
R
No r wave no ___
Anterior septal wall
Myocardial contusion EKG
St elevation in leads looking at injury
Pericarditis EKG
St elevation in all leads
Risk for cardiac tamponade
Pericarditis s&s
Sharp stabbing pain increases w/ resp
Low grade fever
Dyspnea&cough
Chest pain relieved by sitting up and leaning forward
Cardiac tAmponade s&s
Hypotension
Elevated jvd
Pulses paradoxus
Co range
4-8 L/min
CI range
2.8-4.2 L/min/m2
Cvp range
2-6 mm Hg
Blowing noise heard 2 rics increases w/ exhalation
Aortic insufficiency
Med pitch crescendo decrescendo radiating to neck & right carotid. Increases w/ holding breath
Aortic stenosis.
High pitched plateu blowing at apex radiates to Scilla
Mitral insufficiency
Lead 1 and avl look at —– & complex is —-
Lateral wall. Up.
Lead II, III,& avf look at —- & complex goes—-
Inferior wall up
V1 v2 v3 v4 look at
Anterior septal wall
v5 & v6 look at
Lateral wall
V1-v6 have an — wave that —– in each v lead
R wave. Increases.
Inferior wall mi affects
RCA Sinus node:Brady Av node: chb 3rd hb, av dissociation Rv infarction Mitral valve insufficiency Usually asymptomatic
Only give atropine in
Brady with drop in bp
Anterior septal wall mi effects
LAD
Bundle his and bundle branches: mobitz 2 and bbb
Vent sept: vsd
Inferior wall mi w/av dissociation needs a
Pacer
Anterior wall mi w/ mobitz 2 or rbbb 94% mortality unless
Pacemaker inserted
