QUESTIONS AND ANSWERS PASS GUIDE


◉ ERP
Answer: -the longest coupling interval that fails to
conduct/propagate


◉ FRP
Answer: The shortest coupling interval that conducts/propagates
through tissue
-basically right before ERP


◉ RRP
Answer: ERP to beginning of phase 4
-longest coupling interval that results in slowed conduction through
tissue
-so basically right when the tissue begins to slow
-due to slower phase 0 slope


◉ peeling of refractoriness
Answer: -exercise / higher heart rates / isuprel

, -shorter Qt interval (shorter refractory period)
-increased conduction velocity (decreased AH, PR)


◉ decremental conduction
Answer: -at higher heart rates, most tissue has peeling of
refractoriness, but the AVN actually experiences increased ERP and
slowed conduction velocity (because of increased RP's)


◉ Isuprel effect on BP
Answer: -increased systolic
-decreased diastolic (B2 receptors)


◉ sympathetic tone effects on AP
Answer: -faster phase 0 slope = increased conduction velocity
-faster phase 4 slope = increased automaticity
-decreased APD = shorter refractory periods


◉ parasympathetic tone effects on AP
Answer: -slower phase 0 slope
-slower phase 4 slope
-increased APD
