ACCURATE QUESTIONS AND VERIFIED CORRECT
SOLUTIONS WITH RATIONALES || 100%
GUARANTEED PASS <RECENT VERSION>
Action potential ......ANSWER........The graphic representation of
cellular electrical events
Describes the changes in intracardiac voltage that lead to
impulse formation and conduction and, ultimately, to cardiac
contraction
Automaticity ......ANSWER........The ability to initiate impulses
spontaneously
Conductivity ......ANSWER........The ability to conduct an impulse
along the cell membrane
,age 2 of 35
Contractility ......ANSWER........The ability to contract in response
to a stimulus
Depolarization ......ANSWER........A change in the resting
electrical state of the cardiac cell
The inside of the cell becomes more positive and impulse is
spread through the heart
Excitability ......ANSWER........The ability of cells to respond to a
stimulus
Refractory period ......ANSWER........Absolute
Relative
Absolute refractory period ......ANSWER........The cardiac cell is
unable to accept or respond to a stimulus
,age 3 of 35
Relative refractory period ......ANSWER........A stronger than
normal impulse may stimulate the cardiac cell to depolarize
Repolarization ......ANSWER........Return of the cardiac cell to the
resting membrane state
The inside of the cell becomes more negative
Resting membrane potential ......ANSWER........The electrical
charge across the cardiac cell membrane between impulses
About -70 mV
Threshold ......ANSWER........The electrical level at which the cell
will continue to depolarize without additional stimulus
About -60 mV
, age 4 of 35
Sinoatrial node (SA node) ......ANSWER........Located high in the
right atrium, near the junction of the superior vena cava
It is the primary pacemaker of the heart with normal rate
automaticity of 60-100 bpm
Internodal atrial pathways ......ANSWER........Conduct the impulse
from the SA node through the right atrium musculature to the AV
node
Three tracts
- Bachmann's (anterior, fast tract)
- Wenchkebach's (middle)
- Thorel's (posterior, slow tract)
