Cardiac Flashcards
Identify the MI:
ST segment changes in II,III, aVF
Inferior MI (RCA)
Inferior MI tx
2L Fluid
No nitro or Beta Blockers
Which artery blockage would cause type 1 or type 2 block and why
RCA, supplies the SA and AV node
suspected inferior STEMI warrants
RV4 sided EKG
are reciprocal changes in an anterior-septal infarct easily detectable
no, it warrants a posterior EKG
Identify the MI:
ST segment changes in V2, V3, V4
Anterior MI LAD
STEMI MIMICS “ELEVATION”
Electrolytes LBBB Early Repolarization Ventricular Hypertrophy Aneurysm (Ventricular) Thailand (Brugada Syndrome) Inflammation (Pericarditis) Osborne (J) Waves (hypothermia) Non-Ischemic Vasospasm
what is Chapman’s sign
Acute MI in LBBB, notched R wave in Leads 1, AVL or V6
low Sensitivity with high specificitiy
what is Cabreras sign
notching on upslope of S wave in LBBB in leads V3/V4
low sensitivity
STEMI mimics
RAISED ST SEGMENT
Raised Intracranial Pressure Abberrant Conduction (LBBB) Inflammation (Pericarditis) Spontaneous Coronary Artery Dissection (SCAD) Electrolytes (Hyperkalemia) Device (Ventricular Paced Rhythm)
Sodium Channelopathy (Brugada Syndrome) Thoracic Aortic Dissection
Spasm of the coronary arteries (Prinzmetals/Variant Angina)
Embolism (Pulmonary)
Grief (Takotsubo Cardiomyopathy)
Myocardial Infarction recently (leading to ventricular Aneurysm)
Enlarged Ventricle (Left Ventricular Hypertrophy)
Normal for them (early depolarization)
Temperature (hypothermia)
Takotsubo Cardiomyopathy
Stress cardiomyopathy or broken heart syndrome with changes to the shape of the LV
Anteroseptal MI expected ST changes
V1/V2/V3/V4
Treat with MONA/FONA
hitting the LAD
ST segment changes in Lead 1, AVL, V5,V6
Lateral MI (LCX)
CABP for RCA uses what vessel
Saphenous
CABP for LAD uses what vessel
Inferior Mammary Artery
