How does COPD result in atrial fibrillation and predisposition to PEs? - COPD causes pulmonary hypertension, right ventricular hypertrophy, and right atrial enlargement. The right atrial enlargement causes stretching of the atrial tissue and frequently results in atrial dysrhythmias. SA blocks, second-degree AV block type I, and third-degree AV heart block at the level of the AV node would occur in _______________ occlusion - RCA (as seen in inferior wall MIs) There is (more/less) risk of b...

Which effect does parasympathetic stimulation have on the heart? A. It increases peripheral vascular resistance. B. It enhances atrioventricular node function. C. It shortens His-Purkinje and ventricular muscle refractoriness. D. It slows sinoatrial node discharge. - ANSWER- D. RATIONALE: Parasympathetic stimulation slows sinoatrial node discharge. Sympathetic stimulation enhances atrioventricular node function, shortens His- Purkinje and ventricular muscle refractoriness, and increases p...
