common lab tests
certain chemicals in our blood and having heart attacks strokes and high blood pressure chemicals are
cholesterol triglycerides lipoproteins
lipoproteins attached to cholesterol and/or triglycerides transport in blood
high density lipoproteins good cholesterol
low-density lipoproteins bad cholesterol
very low-density lipoproteins associated triglycerides
Test Cholesterol CT
desireable <200 mg/dL
Borderline 200-239 mg/dL
high risk >239 mg/dL

cholesterolTC total amount from diet some made in liver cholesterol essential for life
in excess builkds up in blood vessel walls damage
<150 mg/dL good
150-199 mg/dL borderline
200-499 mg/dL high risk

Triglyserides main way blood transports fat storage tissue cells to burn give energy
after eating large amounts of tris released into blood
Liver also makes triglycerides from extra carbs other calorie-containing chemicals
HDL cholesterol
> 40 mg/dL

good cholesterol attached to high-density lipoproteins involved in keeping cholesterol from being deposited in blolld vessel walls may assist in removing cholesterol
LDL Cholesterol
<100 mg/dL good
130-159 mg/dL borderline
160-189 mg/dL high risk

bad cholesterol fraction of total cholessterol bound to low-density lipoproteins elevated in blood assoc. fatty build up in vessel walls narrow rigid possibly clogged
VLDL cholesterol
<40 mg/dL

VLDL lipoproteins associated with triglycerides in blood vessel disease
TC/HDL-C Ratio

ratio of TC total chol. to HDL-Chol. good predicatabiliy heart disease
hujman heartbeat controlled by
heart's bioelectrical triggering system not working pacemaker
2 parts batterey-powered generator wires connected to heart silver dollar size 7-12 life below collarbone leads WIRES**** threaded into veins leading to heart
local anesth. one hour
most common pacing device
demand pacemaker takes control when heart rate falls below 60 beats pm
heart block stops beating
tacyarrhythmea overly rapid heart beat
other conditions require pacemakers
more sophisticated pacemaker
monitors number of physical changes in body increase or decrease in activity rate-responsive pacemakers slowly raise of lwer heartbeat appropriate level from 60-150 bps
reprogramming implanted generator
cadiologist changes to on-board computer electromagnetic signaling device placed above pacemaker over skin
modern pacemakers are shielded from stray
electromagnetic forces backup mode takes over if electromagnetic field does disrupt main circuit's programming
