Ventricle

Single Ventricle Defects WHAT ARE SINGLE VENTRICLE DEFECTS? Single ventricle defects are heart problems that you were born with (congenital heart defects). Normally the heart has two pumping chambers. These are the right and left ventricles. The right ventricle pumps blood to the lungs to get oxygen. After blood returns from the lungs, the left ventricle pumps it out to the body. Single ventricle defects come in many forms. They can involve one or more valves in your heart and a ventricle that does not pump effectively In almost all cases, a single ventricle defect means blood flow to your body or to your lungs is less than it should be. WHAT ARE THE SYMPTOMS OF SINGLE VENTRICLE DEFECTS? You may continue to have some symptoms of your heart defect as an adult even if you had surgery to correct your heart defect as an infant or child. Your symptoms depend on the type of defect you were born with. If you have had surgery, the success of your surgery also makes a difference. Your symptoms may include:…

1. Based on the information provided, the left atrium and left ventricle are not working properly due to mitral valve not working appropriately. The reason this set of valves was chosen is because in the passage, it stated that the X-Ray show an enlargement in the left atrium and left ventricle. This happen is due to inefficient cycle of blood resulting in abnormal heart sound or heart murmur. Mitral valve of the left side is misshape and less flexible. Mitral valve has a leakage and allows…

Several neuroanatomical abnormalities are implicated in the development of schizophrenia. Enlarged ventricles is an abnormality that causes schizophrenia. Ventricles are canals in the brain that contains cerebrospinal fluid and helps to cushion the brain and the spinal cord. People diagnosed with schizophrenia tend to have a more enlarged ventricles, especially those with negative symptoms. These enlarged ventricles are considered structural abnormalities. Hence, larger canals means less brain…

From the subjective data collected through history taking and objective data gathered from the physical assessment of Mr Jones, the primary differential diagnosis was AR. The left ventricle in AR is typically dilated from secondary to severe volume overload, normally the left ventricle handles both the forward flow delivered from the left atria as well as the backflow of blood from the aorta. The abnormal backflow of blood leads to pathologic changes in the heart in order to compensate for…

Data regarding the cardiovascular system of older adults is slightly limited, due to the fact that older people are usually not included in clinical trials. However, enough research has been done to identify common physiological changes in the geriatric cardiovascular system, such as: increased heart weight; decreased number of myocardial cells with enlargement of remaining cells; increased left ventricle wall thickness; increased arterial stiffness; increased elastin levels; increased collagen…

During one year, the heart initiates approximately 32 million heartbeats to pump blood around the body, beating a total of 60-80 times per minute at a normal pace. It is a highly efficient organ and constantly works to keep our blood circulation going and ourselves alive. The high efficiency of the heart pumping system originates in a conductive system, which is linked to the Sinoatrial (S-A) and Atrioventricular (A-V) node. The Sinoatrial node, also known as the natural cardiac pacemaker, is…

Introduction / 5p- 1200w The most frequent cause of sudden cardiac death is hypertrophic cardiomyopathy (HCM), mainly in young people. It is characterized by thickening in the left ventricle (LV) wall not related to load condition such as aortic stenosis or systemic hypertension (Bing, Knott et al. 2000). It is estimated that approximately one in 500-1000 population. HCM is a complex genetic inherited cardiovascular disease caused by dominate mutation in coding of cardiac sarcomere proteins gene…

The chambers include the right and left atrium as well as the right and left ventricle. The atrium receives blood from the venous system while the ventricles pump blood into the arterial system. These pumps are able to provide circulation out to the pulmonary (right pump) and systemic system (left pump). When conducting this lab experiment, it is important to be familiar with an electrocardiogram. An electrocardiogram measures the electrical activity of the heart. The electrocardiogram displays…

The decreased in resistance is caused by vasodilation done by specific metabolites like AMP, H+, and K+. Consequently, an increase in blood flow accords with a higher cardiac output that is determined by heart rate and stroke volume. At high work rate, cardiac output (amount of blood pumped by the heart per minute) composed by the product of stroke volume (amount of blood ejected from the left ventricle per beat) and heart rate can reach up to 90% of theoretical maximum value as well as having…

The blood is moved through the pulmonary capillaries and alveoli where it exchanges the CO2 with fresh O2 and then moves out of the lungs via pulmonary veins and moves out of the other chambers of the heart and to the body and once again completes the cycle. It stands to reason that due to the short distance of a trip through the pulmonary system pressure in the lungs would be less than arterial pressure. So imagine if you will that the pathways in the lungs were narrowed and the pressure…
