Describe the ECG changes and artery effected in an inferior wall MI
|
ST elevations in II, III and aVF, depressions in I, aVL
RCA (80%) or RCX (20%) |
|
|
ECG in lateral MI
|
ST elevations in I, aVL (high lateral), V5, V6,
depressions in II, III, aVF RCX or MO?? |
|
|
ECG in anterior wall MI
|
Elevations in V1-V6, no recpirocal depressions,
LAD |
|
|
ECG in posterior wall MI
|
depressions in V1, V2, high R in V1-V3, can flip leads to do posterior leads (v7-v9) and get elevations in those
RCX |
|
|
Septal MI
|
elevations in V1-V4
LAD |
|
|
What ECG changes are seen with a PE?
|
S1Q3T3: a pronounced s wave in lead I, a q wave in lead III, and an inverted T wave in lead III. There can also be right axis deviation and a peaked p wave in lead I.
|
|
|
What can be seen somtimes on CXRAY with a PE?
|
Hampton's hump: a wedged shape infiltrate that represents an infarct.
|
|
|
What are the important parts of the cardiac markers?
|
Troponins rise in 4-6 hours and remain elevated for up to ten days. CK rise in 2-3 hours and return to baseline in 3-4 days
|
|
|
What is the HEAD neumonic for the causes of syncope?
|
H:hypoxemia, hypoglycemia
E:epilepsy A:anxiety D:dysfunctional brain stem, vertebrobasilar ischemia, SAH |
|
|
What about the HEART causes?
|
H:heart attack, MI
E:PE A:Aorta( aortic obstructions, hypertrophic obstructive cardiomyopathy, aortic stenosis, atrial myxoma R:rhythm disturbances such as sick sinus syndrome, av block T:tachyarrythmias (VT) |
|
|
What about the vascular causes (VESSELS)?
|
V:vasovagal
E:ectopic S:situational (micturition, defecation, cough, valsalva) S:subclavian steal E:ENT (glossopharyngeal neuralgia) L: low systemic vascular resistance S=sensitive carotid sinus |
