significance of heart beat
number of times the ventricle contracts in one minute... nomral is 60-100
common nursing diagnosis
decreased cardiac output
(nausea, SOB, Increase HR, decrease BP, skin color change, decreased urinary output)
ineffective tissue perfusion
(something interfering with blood flow, ex. blood clot)
excessive fluid volume
(cooling extremities, fluid in lungs)
recovery phase: muscle of the heart has already contracted and is returning to ready state.
SA node (located in Upper rt. atrium)
AV node (located in bottom rt. atrium)
bundle of his
bundle branches: break off into the ventricle
pukinje fibers: go into the muscle walls of the ventricles and cause contraction.
white: right arm, right upper chest
green: right lower abdomen
black: left arm, left upper chest
red: left lower area
can have positive deflection (above baseline)
can have negative deflection (belowe baseline)
sometims it's imaginary
begining of P wave to the QRS complex
time it takes for the electrical conduction to go through atria and av node
first a negative deflection, the posative, then negative again
end of S wave to the begining of T wave
May be flat (normal), elevated, or depressed
change indicates cardiac problems
8 steps for ECG interpretation
determine heart rate
determine heart rhythm
is there a P wave for each QRS
Determine PR interval
Determine the QRS interval
Is there a T wave after each QRS
determine QT interval
what is the client's response and VS
normal sinus rythm
heart rate between 60-100
always a P wave for each QRS
PR interval less than 0.12
Normal QT interval less than 0.44
