CV II EKG Flashcards
Atrial hypertrophy
Lead V1
assess atrial enlargement
biphasic P wave (+=RA, -=LA)
Leads II, III, aVF : increased amplitude
Ventricular hypertrophy
V1: biphasic P wave RVH= large R wave LVH: large S wave V5: large R wave
LVH: DKG of S wave in V1+ R wave in V5?35mm
inverted T waves
Strain patters and depressed humped ST
strain pattern
in LV is enlarged it is training
repolarization is abnormal
=asymmetrical and scooping ST segments
Infarction
ST depression
T wave inversion
acute myocardial injury
ST elevation if transmural infarction
“fireman’s hat sign”
necrosis
Q waves present
inferior MI
II, III, AVF
RCA
anterior MI
V1-4
LAD
Lateral MI
I, AVL, V5-6
Circumflex
LBBB
EKG is INVALID dx tool for acute MI
hyperkalemia
flat and wide P
Wide QRS
Peaked T
IN ALL LEADS
Hypokalemia
flat T
prominent U
Hypercalcemia
short QT interval
wide T wave
Hypocalcemia
Long QT
flat T waves
hypothermia
sinus bradycardia long PR wide QRS prolonged QT osborn wave = extra deflection at the end of the QRS
