Unit 6A Sigs | Baamboozle - Baamboozle | The Most Fun Classroom Games!

Explain how pulmonary hypertension increases the pressure/afterload on the right side of the heart. (SIGS 6.4b)

normally very low pressure/resistance; emboli blocks flow from RV--> resistance increases--> inc. afterload on RV (needs more work to contract against resist)

Describe how cor pulmonale can result in right-sided heart failure. (SIGS 6.4b)

cor pul.->RV work harder->enlargement & thickening of RV (remodeling)-> contraction decreased-> conduction path stretched-> V. arrhythmia-> Vfib-> RHF

Describe integrative approaches to asthma (Sigs 6.4a)

Avoid triggers, mindfulness, yoga, 4-7-8 breathing, meditation, Med. diet, anti-inflamm. diet

Explain the relationship of HCM and heart failure with preserved ejection fraction (HFpEF)(Sigs Case 6.3b)

diastolic dysfunction (early diastolic relaxation) + LV hypertrophy (concentric)- thick wall = pressure overload + less volume (EDV-ESV/EDV) = up EF

Explain how atropine alters conduction. (SIGS 6.1b)

M2 muscarinic antagonist--> block muscarinic receptor--> decrease parasympathetic response--> increase HR, decrease phase 4 of nodal cells

Check

Explain how multiple wandering re-entrance circuits can result in atrial fibrillation. (SIGS 6.1a)

Wandering re-entrance circuits able to continuously find excitable tissue--> depolarization of atria--> fibrillatory contractions in atrial myocytes

What is the significance of D-dimer elevation in the formation and diagnosis of PE.(Sigs Case 6.4b)

indicates clots are forming and breaking somewhere; highly sensitive, not specific to PE/DVT (must be coupled w/ suspicion of PE)

Differentiate between oxyhemoglobin and carboxyhemoglobin. (SIGS 6.5a)

Carboxyhemoglobin: carbon monoxide (240x affinity vs oxygen) & hemoglobin; oxyhemoglobin: oxygen & hemoglobin

Describe integrative approaches to atrial fibrillation. (SIGS 6.1b)

Med. diet, stress reduction, no alcohol or caffeine, diet high in magnesium, fish oil, CoQ10

Describe how cardiac chamber dilation results in global hypokinesis and systolic dysfunction.(Sigs Case 6.2b)

constant backup fluid-> dilation chambers-> decrease ability to contract & overstretching-> impaired contraction-> less EF-> systolic dysfunct-> systolic fail
