|
Systemic conditions that increase transvalvular flow (ie. benign ejection or diastolic murmur) include:
|
fever, anemia, thyrotoxicosis, and pregnancy
|
|
|
Causes of Pansystolic murmur:
|
tricuspid/mitral regurge, VSD
mitral: heard best at apex- has uniform intensity through out systole. S1-S2. radiates to the axilla the smaller the VSD the louder, also may have a thrill |
|
|
Late systolic murmur, continues to A2, think....
|
often regurgitant mitral due to prolapse... note mid systolic click.
|
|
|
DDx for diastolic murmurs...
|
early decrescendo due to incompetent A or P; mid/late "rumbling" murmurs turbulent flow past T or M
|
|
|
continuous murmur
|
patent ductus arteriosus
|
|
|
EKG abnormalities with transmural infarct.
|
ST segment elevation, T wave inversion, and Q waves in injured region.
|
|
|
EKG abnormalities with epicardial infarct.
|
ST segment depression, and T wave inversion in injured region.
|
|
|
Condidtions confused with acute MI.
|
Aortic dissection, pericariditis (diffuse ST elevation), pulmonary embolism, esophogeal spasm/reflux, pneumothorax
|
|
|
Serum BioMarkers in MI, temporal sequences:
|
Myoglobin - CK-MB - Troponins
Myo- 2-4 hrs, rapidly cleared in Kidney, not specific, non Dxstic CK-MB- rise 3-12 hours following, delyed 24hr peak; N after 48, Use reletive index vs total. Troponins- GOLD STD, absent in health pts. Must get sample to Lab STAT, TnT in heart vs TnI in skeletal muscle (i think). |
|
|
Define Cardiac Shock
|
Severely decreased cardiac output and hypotension (systolic <90); greator than 40% of ventricular mass is infacted. Mortality 70%
