CSEP CEP Exam Questions and Answers With Real Solutions 2024 Autorythmic - correct answer.Self Exciteable, and repeatedly generate action potential eg. natural pace maker Cause of fundamental heart rhythm - correct answer.NOT by nerve impulses or hormones, rather electrical impluse SA Node - correct answer.Main natural pacemaker, faster conduction than autorhytmic fibres The Heart's electrical flow - correct answer.SA Node to AV Node - AV Node to AV Bundle - Bundle of HIS to L and R branches to Apex and Purkinje FIbres (which then cause systolic phase and ventricle contraction HR Increase - correct answer.Diastolic period decreases - causes an increase in MAP (main arterial pressure) ECG - correct ors electrical activity being produced by SA node (cardiac rhythm). P wave = atrial depolarization QRS complex - ventricle depolarization T wave = ventricle repolarization. T-P interval = diastolic filling time for atria. ECG Results - correct answer.Long P - R interval = first degree AV block Average P-R interval is .12 - .20 seconds No P wave - atrial fibrillation Waves all over the place - ventricular fibrillation QRS complex should be less than .12 seconds Limitations of ECG - correct answer.Only records electrical activity so it is still important to measure mechanical factors including pulse and blood pressure. Circulatory System overview - correct answer.Right atrium - right ventricle - pulmonary artery - lungs - pulmonary vein - left atrium - left ventricle - aorta - arteries - arterioles - capillaries - venules - veins - superior/inferior vena cava. Arteries vs Veins - correct answer.Arteries are under high pressure so they have thicker strong walls. Veins are under less pressure so they have thin distensible walls. The main purpose of circulation is to deliver oxygen and nutrients to all tissues of the body and eliminate waste products. HR Response to Exercise - correct answer.SV = EDV - ESV (end diastolic vol - end systolic vol) Ejection fraction = SV / EDV Cardiac output (Q) = HR X SV O2 consumption = Q X Avo2 difference RPP (how hard the heart is working) = HR X SBP HR in Moderate intensity, steady state - correct answer.During steady state moderate intensity exercise all variable increase then level off once they reach a level where they meet the oxygen/nutrient demand (consumption and disposal) of the working muscle. If you level off at a lower HR this means your CV and muscular system is more efficient ie. You are in better shape. Cardiovascular Drift - correct answer.The decrease in plasma volume late in exercise causing decreased SV and increased HR in order to maintain Q. BP Response to Exercise - correct answer.Large increase in systolic blood pressure during exercise but very little, if any change in diastolic blood pressure. Causes moderate increase in MAP. If there is ever a sudden drop in blood pressure during exercise or no increase during onset of exercise then stop immediately. Blood pressure may drop below resting levels after exercise if you do not do a cool-down due to prolonged vasodilation or arterioles, this is what causes a "light headed" feeling. Cool-down is important to keep the HR slightly elevated to avoid such a drastic drop in BP and fainting
