avF
Vessel involved in R. ventricular MI
RCA
EKG leads involved in R. ventricular MI
V4 on R sided EKG
Treatment of Right sided MI
Aggressive fluid resuscitation
What peaks first? (AKA best for recurrent MI)
Myoglobin
Most common cause of death post-MI
arrhythmia
“Step Up” in O2 post MI
septal rupture
Persistent ST elevation 1 month later + systolic MR murmur
ventricular wall aneurysm
“Cannon A Waves”
AV dissociation due to Vfib or 3rd degree heart block
How do you diagnose Prinzmetal’s Angina?
Ergonovine simulation test
“Progressive prolongation of PR interval followed by a dropped beat”
Wenckebach (Mobitz I)
“Varying PR intervals w/ >3 morphologically distinct P waves”
Seen in elderly w/ COPD
Multifocal Atrial Tachycardia
“>3 beats w/ QRS <120ms at a rate of >120 bpm”
V tach
“Delta wave”
“Short PR Interval w/ wide QRS”
WPW
Treatment of WPW
Procainamide
Treatment of SVT
Carotid massage
Ice bath to the face
Peaked T waves
Wide QRS
Short QT
Prolonged PR
Burn victim/Crush injury
Hyperkalemia
Systolic Crescendo decrescendo murmur
AS
Parvus et tardus murmur
AS
Systolic murmur that increases w/ valsalva
Hypertrophic Cardiomyopathy
Late Systolic murmur with a click
MVP
Holosystolic murmur that radiates to axilla
MR
Holosystolic murmur with a late diastolic rumble
VSD
Wide, fixed split S2
ASD
Rumbling diastolic murmur with an opening snap
MS
Blowing diastolic murmur
AR
“Water hammer pulse”
AR
Distinguishing CHF from pHTN
PCWP high in CHF, normal in pHTN
Right Ventricular infarct symptoms
Hypotension Tachycardia Clear lungs JVD NO pulsus paradoxus
Causes of Systolic CHF
Viral
EtOH (reversible)
Cocaine
Chagas
Causes of Diastolic CHF
HTN
Amyloidosis
Hemachromatosis (reversible)
Given to improve survival in NYHA Class III and IV
spironolactone
