Review Sheet Excercise free essay sample

Ensures that deportation proceeds In an orderly manner from atria to ventricles ; accelerates and coordinates earth activity to effectively pump blood. Electrocardiography 3. Define EGG. Recording of electrical changes occurring during heart actively 4. Draw an EGG wave form representing one heartbeat. Label the P,SIRS, and T waves: P-R interval: the segment, and the Q-T interval. 5. Why does heart rate increase during running? Exercise raises heart rate by acting through the sympathetic nervous system.Sympathetic nerve fibers release morphogenesis on the heart and the pace maker fires more rapidly. 6. Describe what happens in the cardiac cycle in the following the heart is in relaxation (diastole) situations. 1 . 2. Popularization of the arteries 3. Contraction of the aria 4. deportation of the ventricles contraction of the ventricles 6. Revitalization of the ventricles 7. Define the following terms 1 . Tachycardia: Heart rate over 100 beats/minute 2. Radically: Heart rate below 60 beats/Emanuel 3. Fibrillation: Very rapid uncoordinated myocardial activity 8. Which would be more serious, trial or ventricular fibrillation? Ventricular fibrillation.

Abnormalities of the heart valves can be detected more accurately by auscultation than by electrocardiography. Why Is this so? Most often serious valve problems can be detected (heard) with a stethoscope.However, since valves are not part of deportation pathway of the heart, their Inefficiency would not be reached on an EGG, Review Sheet Exercise 31: Conduction System of the Heart and Electrocardiography By begetter Node. AS node, VA Node, VA Bundle, left and right bundle branches, Purging fibers At what structure in the transmission sequence is the impulse delayed? VA Node Allows completion of trial contraction before initiation of ventricular systole. 2. Even though cardiac muscle has an inherent ability to beat. He nodal system plays a critical role in heart physiology.What is that role? Ensures that deportation proceeds in an orderly manner from atria to ventricles ; accelerates and coordinates Recording of electrical changes occurring during heart activity 4.

Brickyard: Heart rate below 60 beats/minute than by electrocardiography. Why is this so? Most often serious valve problems can deportation pathway of the heart, their inefficiency would not be reached on an EGG.
