ACS Flashcards
Right coronary artery supplies the
Right atrium and ventricle
Inferior left ventricle
Posterior septal area
Left coronary artery divides into
Circumflex artery
left anterior descending artery
Circumflex artery supplies
left atrium
posterior left ventricle
Left anterior descending supplies the
anterior left ventricle
anterior septum
ECG changes in a STEMI
ST segment elevation
New left bundle branch block
ECG changes in an NSTEMI
ST segment depression
T wave inversion
Pathological Q waves suggest
deep infarction involving the full thickness of the heart
Q waves typically appear
6 or more hours after the onset of symptoms
Left coronary artery infarction will show on ECG leads
I, aVL, V3-V6
Left anterior descending infarction will show on ECG leads
V1-V4
Circumflex artery infarction will show on ECG leads
I, aVL, V5-6
Right coronary artery infarction will show on ECG leads
II, III and aVF
PCI should be performed in STEMI patients
within 2 hours of presenting
Alternative causes for a raised troponin other than an MI
CKD, sepsis, myocarditis, aortic dissection, PE
If PCI cannot be performed within 2 hours thrombolytics such as … should be used
streptokinase, alteplase, tenecteplase
