CRAT TEST PREP (Anatomy)Absolute refractory period - correct answer-• cardiac cells cannot respond to any electrical
stimulus
• From onset of the QRS to peak of T wave
Atrial Flutter - correct answer-•Regular or Irregular
• Atrial Rate 250-400 BPM
Atrial Tachycardia w/block - correct answer-• Irregular Rhythm
• Rate: Atrial Rate 140-250 BPM ventricular Rate slower
• P-waves: present/uniform
• PRI: unmeasurable
QRS: 0.06- 0.11
Automaticity - correct answer-Ability of the cardiac cell to initiate an impulse
Circumflex artery (CX) [back] - correct answer-Runs along the groove between the left
atrium and ventricle then winds around to the back (posterior) portion of the heart
Conductivity - correct answer-Ability of the card excel to conduct or transmit an impulse
Contractility - correct answer-Ability of the cardiac so it's a contract/pump in response to an
electrical impulse
Excitability - correct answer-Ability of the car excel to respond to an impulse
Left anterior descending artery (LAD) - correct answer-Location: Front anterior surface of the
left ventricle
Supplies the anterior wall of the left ventricle, lateral wall and inter ventricular septum.
Obstruction if this artery causes infarction of large muscular area in the left ventricle and may
be fatal
Obtuse marginal - correct answer-Supplies the lateral and posterior wall of the left ventricle
and left atrium
Paroxysmal Atrial Tachycardia
Paroxysmal = Sudden onset/offset - correct answer-• Irregular Rhythm
• Rate: Depends on underlying rhythm at least 140-250 BPM at time of event
• P-Waves: Hidden
• PRI: Normal with underlying rhythm
QRS: 0.06-0.11
Relative refractory period - correct answer-• A portion of the cardiac cells have repolarizing
are able to respond to strong electrical stimulus
• Downslope of T wave (Peak of T wave to end of T wave)
