Leads I, II, III.
3 views, no anterior. No LAD view
5 lead EKG
- Electrodes,
- Leads
- Views
RA, LA, LL, RL, chest lead (ususally V1 or V5).
I, II, III aVR, aVL, aVF, V.
7 views
Best lead for
- Arrythmia,
- Ischemia
II.
V5.
What gain and filtering capacity should be set at
Standardization. Diagnostic mode
What filtering capacity is
Filters out unwanted noise/artifact
Indicators of acute ischemia on ECG (5 items)
- ST elevation >1 mm,
- T wave inversion,
- Q waves,
- ST depression, flat or downslope >1 mm.
- Peaked T waves
Where inferior wall ischemia shows, artery
II, III, AVF
Supplied by RCA
Where lateral wall ischemia shows, artery
I, AVL, V5-V6
Circumflex of LCA.
Where anterior wall ischemia shows, artery
V3-4
Left Coronary Artery
Where anteroseptal ischemia shows, artery
V1-V2
LDA
What SBP and DBP correlate with
Myocardial o2 requirement changes. Coronary perfusion pressure
MAP calculation
SBP + 2DBP/3
Proper NIBP cuff width
40% of circumference of extremity
Proper NIBP cuff length
Must encircle at least 80% of extremity
What creates a falsely high BP (3 items)
- Cuff too small or loose,
- extremity below heart,
- arterial stiffness in htn or PVD.
What creates a falsely low bp (4 items)
- Cuff too big,
- above heart,
- poor tissue perfusion,
- too quick of deflation
