BA - conduction

Conduction sytem

QuestionAnswer
List the 4 pacemaker sites SA AV Junction Ventricular Atrial
PR interval that identifies conduction delay thru the AV Junction > 0.20
How do you calculate heart rate with an irregular rhythm count the number of P waves and multiply by 10
How do you calculate heart rate with an regular rhythm count the number of small blocks in P-P interval and divide by 1500
Lead Placement/Color RA LA Chest RL LL white black brown green red
Represents depolarization of atrial electrical cells P wave
Represents time the impulse is passing thru the AV junction to the ventricles PR segment
Time required for electrical impulse to depolarize atria, travel thru AV node & Bundle of His to ventricles PR interval
Normal PR interval 0.12 - 0.20
Measures how long it takes the ventricles to depolarize and repolarize QT interval
Normal QT interval 0.35 - 0.43
Measures time for electrical impulse to transverse both ventricles QRS width
Normal QRS width 0.10 or less
The first positive deflection from the baseline R wave
negative deflection from baseline following the R wave S wave
represents beginning of ventricular repolarization ST segment
represents last 2 phases of ventricular repolarization T wave
represents depolarization of the ventricle QRS complex
the first downward or negative deflection from baseline Q wave
Normal QRS width 0.10 or less
Pacemaker Site: no P wave with normal QRS Pacemaker Site: AV Junction
Pacemaker Site: no P waves with wide QRS Pacemaker Site: Ventricles
Pacemaker Site: PR interval < 0.12 Pacemaker Site: AV Junction
Pacemaker Site: PR interval 0.12 or greater Pacemaker Site: SA node or Atria
"pacemaker of the heart" 60-100 bpm SA node
Not a back up of the SA node Atrial pacemaker site
Monitor displays only this rate ventricular
Signs and symptoms of low cardiac output -decreased level of consiousness -weak, thready pulses -loss of peripheral pulses -decreased urine output -cool, clammy skin -delayed capillary refill -chest pain -decreased blood pressure -CHF -AMI
