Rhythm Recognition Miscellanous Flashcards
The atria contracts, sending the additional 20-30% of the blood to the ventricles?
Atrial kick
What regulates the involuntary actions of the body?
Autonomic nervous system
What is your fight, flight, or freeze?
Sympathetic nervous system
What is your rest and digest?
Parasympathetic nervous system
What is refractoriness?
The time the cells need after they discharge before they can react to another stimulus
Sits right at atrium and travels to AV node by means of intranodal pathway?
Sinoatrial Node
Group of cells that help the impulse travel from right atrium to left atrium?
Bachman bundle
Sits in lower section of right atrium. Allows a pause so the atria can depolarize and empty before the ventricle contracts.
Atrioventricular node
Bundle of His joins the left and right bundle branches leading to the purkinje fibers?
His - Purkinje system
60-100?
SA node
40-60?
AV node
20-40?
Purkinje fibers
What should you check daily for someone on tele?
THE ELECTRODES!
PR interval
0.12-0.20 seconds
QRS complex
0.11 seconds or less
QT interval
0.36-0.44 seconds
What is a sinus pause?
Occurs when the SA node fails to initiate an impulse. Looks like sinus, then aystole, then back to sinus.
What are the H’s and T’s of ACLS?
Hypoxia, Hypovolemia, Hypothermia, Hypo or Hyperkalemia, H+.
Toxins, Tamponade, Tension pneumothorax, Thrombus.
What is undersensing?
Fails to sense, see patient’s own intrinsic beats. Fires inappropriately and the patient gets too much.
What is oversensing?
Too sensitive, recognizes artifact or interference. Does not fire when it should and the patient isn’t getting enough.
VADTIO 123
V = ventricle
A = atrium
D = dual
T = triggered pacing
I = inhibit pacing
O = not applicable
1 = chamber being paced
2 = chamber being sensed
3 = response to sensed event
