ACCURATE QUESTIONS AND VERIFIED CORRECT

SOLUTIONS WITH RATIONALES || 100%

GUARANTEED PASS <RECENT VERSION>

depolarization ......ANSWER........- inside of cell becomes positive,

outside negative


- contraction


- na+ channel opens


- ELECTRICAL


repolarization ......ANSWER........movement of cells = inside is

negative again


- na+ channels close, k+ channels open

,age 2 of 43




- MECHANICAL


p wave


qrs wave


t wave ......ANSWER........- (p) atrial depolarization


- (qrs) ventricular depolarization


- (t) ventricular repolarization


refractory period ......ANSWER........per of time where cardiac

cells cannot respond to stimulus


absolute refractory period ......ANSWER........beginning of qrs to

peak of t wave

,age 3 of 43




relative refractory (vulnerable per of repolarization)

......ANSWER........- cardiac cells have repolarized enough to

respond to strong stimulus


- during this per a strong stimulus may overtake the pacemaker

of the heart


- ex. PVC during vulnerable period may turn into vtach or

torsades


- prolonged QT interval inc possibility


causes of prolonged qt intervals ......ANSWER........haldol,

bradycardia, hypokalemia


automaticity ......ANSWER........ability of pacemaker cells to

initiate electrical impulse

, age 4 of 43




excitability ......ANSWER........ability of muscle cells to respond to

outside stimulus


conductivity ......ANSWER........ability to recieve electrical stimulus

and conduct impulse to adjacent cells


contraction ......ANSWER........cardiac cells shorten = muscular

contraction in response to electrical stimulus


sa node ......ANSWER........- primary pacemaker of heart


- 60-90 bpm


av node ......ANSWER........delay = atrial contraction +

ventricular filling


- 40-60 bpm
