NYU EKG Test EXAM WITH CORRECT ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
ANSWERS
most severe block is.... ||\\||\\ ||\\||\\ ||\\||\\
in left ventricle
||\\||\\ ||\\||\\
sympathetic NS ||\\||\\
fight or flight ||\\||\\ ||\\||\\
-SA node increases firing of impulses
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
parasympathetic NS ||\\||\\
rest and digest ||\\||\\ ||\\||\\ ||\\||\\
-vagal nerve ||\\||\\
2 types of cardiac cells
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
-electrical cells ||\\||\\
-myocardial cells ||\\||\\
electrical cells (characteristics) ||\\||\\ ||\\||\\
-automaticity
-excitability
-conductivity
automaticity
cell's ability to spontaneously generate impulses
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
excitability
cells ability to receive and respond to an impulse
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
conductivity
ability to receive impulse and send to someone else ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
P wave
||\\||\\
, atrial depolarization ||\\||\\
-made by the SA node in atria ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
QRS complex ||\\||\\
ventricular depolarization ||\\||\\
repolarization
relaxation
-chambers fill with blood ||\\||\\ ||\\||\\ ||\\||\\
-atrial and ventricular happen at the same time ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
-we don't see a wave associated with atrial
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
T wave
||\\||\\
ventricular repolarization ||\\||\\
Impulse rates ||\\||\\
-SA node: 60-100 bpm ||\\||\\ ||\\||\\ ||\\||\\
-AV node: 40-60 bpm ||\\||\\ ||\\||\\ ||\\||\\
-purkinje fibers (ventricles): 20-40 bpm ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
where is SA node found ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
right atrium ||\\||\\
where are purknje fibers found ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
ventricles
relative refractory period ||\\||\\ ||\\||\\
starts at the t wave ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
-period after firing where other impulses can be noticed ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
-a sudden change during this period on the t wave can put you in a fatal arrythmia
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
ECG graph paper ||\\||\\ ||\\||\\
-each box= 0.04 sec ||\\||\\ ||\\||\\ ||\\||\\
-5 boxes = 0.2 sec
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
