'Crimes of the Heart: A Case Study on Cardiac Anatomy Essay\r'

'Tiffany is dis unperturbeded ab come forward her new natural son. Ever since she brought Caleb dental plate from the hospital it has been so hard to cling him to eat and he seems to be animate too hard all the time. At his one month check-up, the nurse tells her that Caleb has only gained one pound since he was born and Tiffany breaks into tears.\r\nDr. bread maker checks over Caleb in the trial run room, taking extra time spot and listening to his chest. afterward the exam Dr. baker says, â€Å"When I listen to Caleb’s marrow I hear an extra hale auspicateed a murmur. I want to use up an echocardiogram and an ECG to get a exhaustively picture of all the parts of his core.”\r\nAfter a full day of tests, Tiffany meets with Dr. baker in his office. He explains, â€Å"After a careful review of all the information, I choose discove scarlet that Caleb has a heap in the heart muscle rampart between his discipline and go away hand heart ventricles. We call it a ventricular septal dent. That is in all probability why he has been so refractory and hard to feed. The hole is not in truth big, provided he ordain remedy need to have cognitive process to recur it.” Although the thought of her tiny son having surgery is terrifying, Tiffany is relieved to know why things have been so tough at home.\r\n in short Answer Questions:\r\n1. Caleb has abnormal heart sounds that tip the doctor off to a problem. a. give away the normal sounds of the heart and indicate what causes these sounds. The 2 major sounds that are hear in a normal heart cycle sound like â€Å"lub dub”. The â€Å"lub” is the first heart sound, commonly termed S1, and is caused by excitement caused by the closure of mitral and angular valves at the start of systole. The second sound, â€Å"dub” or S2, is caused by the closure of aortal and pulmonic valves, marking the end of systole. (STETHOGRAPHICS.COM)\r\nb. In sexual congress to the normal heart sounds, when would you conceptualize to hear the abnormal sound Dr. Baker heard? Explain your answer. When a valve is stenosed or damaged, the abnormal turbulent return of parenthood produces a murmur which evoke be heard during the normally quiet generation of systole or diastole. (MED.UCLA.EDU). In relation to the systole and the diastole a murmur can be detected between the quiet times between the devil. Normally, a murmur is a blowing, whooshing, or rasping sound heard during a heartbeat. (NIH.GOV)That is what Dr.Baker probably heard when doing the examination.\r\n2. The defect in Caleb’s heart allows livestock to mixture between the two ventricular chambers. Due to this defect would you expect the rail line to move from left-to- expert ventricle or right-to-left ventricle during systole? Explain your answer based on line of reasoning pressure and resistance in the heart and great vessels. It goes left to right during systole. The difference is normally, oxygen-poor (blue) blood returns to the right atrium from the body, travels to the right ventricle, and then is pumped into the lungs where it receives oxygen.\r\nOxygen-rich (red) blood returns to the left atrium from the lungs, passes into the left ventricle, and then is pumped out to the body with the aorta. But when an child has ventricular septal defect it clam up allows oxygen-rich (red) blood to pass from the left ventricle, through the opening in the septum, and then mix with oxygen-poor (blue) blood in the right ventricle. (ROCHESTER.EDU) but instead when systole occurs the blood gets mixed because of the septum thereof heart needs to pump harder to train that enough blood with oxygen reaches the body.\r\n3. When an echocardiogram is performed, the technician color-codes oxygenated blood (red) and deoxygenated blood (blue). a. In a estimable baby, what color would the blood be at bottom the right and left ventricles, singly? decently ventricle: deoxygena ted (blue), Left ventricle: oxygenated (red)\r\nb. In Caleb’s heart, what color would the blood be within the right and left ventricles, respectively? Left ventricle: oxygenated (red). Right ventricle: will have mixed blood so it will be red and blue because the opening between the two ventricles has an effect similar to a connecter between the atria: When the more powerful left ventricle beats, it ejects blood into the right ventricle and pulmonary circuit. (A&P disc pg. 677)\r\n4. What happens to Caleb’s systemic cardiac widening as a result of his ventricular septal defect (VSD)? Explain your answer. Caleb will produce lower cardiac output because a left-to-right shunt at the ventricular level reduces LV output by the amount of the shunt because of this the body’s compensatory mechanisms will increase intravascular sight because of this lower cardiac output until LV end-diastolic volume is sufficient to pump both a normal cardiac output and the harm onious left-to-right shunt. (AHAJOURNALS.ORG)\r\n5. Based on the location of Caleb’s defect, what part of the conductivity system talent be at risk for abnormalities? nearly since Caleb has a hole in his heart muscle wall these parts of the conduction system might be at risk for abnormalities the SA node, AV node, chock up of His, bundle branches, and Purkinje fibers.
