YOU CAN DO THIS! Flashcards
Common major complication from MI
Arrhythmias!
MI - exercise testing can be performed when
3 days after an MI
CHF
Left sided! associated with signs of pulmonary edema
Right sided - associated with systemic venous congestion
Right ventricle to
LUNGS
Left ventricle to
BODY
Hypertension - Normal
Below 120/80
Hypertension - Elevated
Systolic btw 120-130
AND Diastolic less than 80
Hypertension - Stage 1
Systolic btw 130-139 OR
Diastolic btw 80-89
Hypertension - Stage 2
Systolic at least 140 OR
Diastolic at least 90
Hypertension - Hypertensive crisis
Systolic over 180 AND/OR
Diastolic over 120
Tuberculosis spread by
aersolized droplets!
Incubation 2 to 10 wks
Primary disease 10 days to 2 wks
TB precautions
Mask and follow universal precautions
Pt must wear mask if leave room
Right coronary artery supplies
Right atrium
Most of right ventricle
AV node
SA node in 60%
RA = which valve to RV
TRIcuspid
Deoxygenated blood
Pulmonary artery
L coronary artery divides into
L anterior descending
Circumflex
Left anterior descending supplies
Anterior surface of LV and portions of IV septum
Circumflex supplies
Lateral and inferior surfaces of LV and portions of LA
40% SA node
AV valves (Tri and Bi) prevent backflow into atria during
ventricular cx SYSTOLE
Semilunar valves (Pulm and Aortic) prevent backflow from aorta and pulmonary artery into ventricles during
DIASTOLE
Inherent AV node rate
40-60 bpm
Cardiac Output is what and what is norm
Amount of blood that leaves the ventricles per minute
4-6 L/min
Stroke Volume is what
What is norm
the volume of blood ejected with each myocardial contraction
Normal is 55-100 mL/beat
Stroke volume is influenced by
Preload! The amount of blood in the ventricle at the end of diastole
Contractility!
Afterload!
Preload
The amount of blood in the ventricle at the end of diastle
Afterload
The force the LV must generate during systole to overcome aortic pressure and open the aortic valve
SV and Preload
SV will increase with an increase in preload
Contractility and afterload
Contractilty will decrease with an increase in afterload
EF
55-75%
Mean arterial pressure is what
Normal is what
Sum of SBP and 2xDBP, divided by 3
Normal is 70-110 mmHg
Heart sounds - S3 is associated with
CHF
Heart sounds - S4 is associated with
hypertension or MI
Central venous pressure measures what
Measures right atrial filling
Pulse pressure is measured how
Sys - dias
BP is what equation
CO * total peripheral resistance
Hyperkalemia - EKG
Peaked T waves Wide PR interval Wide QRS Dec rate and force of cx Can lead to cardiac arrest!!!
Hypokalemia - EKG
Produces flat T wave and ST depression B LE cramps Prolonged QT Prolonged PR Arrhythmias may progress to vfib
Hypercalcemia - EKG
Shortened QT
Increased heart actions
Hypocalcemia - EKG
Prolonged QT
First degree heart block
Really long PR interval; all else normal
