Regional Myocardial Infarction

In patients with left ventricular (LV) failure, myocardial infarction, congenital heart disease, and pulmonary hypertension, RV function is an important predictor of mortality and quality of life.
There are limitations to echocardiographic techniques currently used in clinical and academic practice to evaluate RV function. However, regional myocardial wall motion detection by M-mode and tissue Doppler velocities are probably the most useful methods in clinical practice. The main limitation in assessing RV function by two- dimensional guided M- mode using the long axis motion is that it only represents the inflow free wall segments missing the outflow tract and the septal contribution to the overall RV function. Additional measurements of

    Second, their left side of the heart has a blockage and blood buildup, which is abnormal and will not have a normal electrical signal such as the P-wave and T-wave, throughout the heart. The P-wave and T-wave will have a distinct pattern because the atrial and ventricle will not depolarize and repolarize normally. The EKG for this patient will have a longer QRS complex and T wave because the left atrial and ventricles will not repolarize efficiently. The P-R and Q-T interval will also have a longer range than 0.20 second due to weaken electrical conduction that causes by the heart…

    Jugular Veins Lab Report

    It is best to examine the right internal jugular vein because it follows a more direct anatomical path to the right atrium of the heart. The column of blood inside the internal jugular vein serves as a manometer, reflecting pressure in the right atrium. The higher the column, the greater the venous pressure. Raised venous pressure reflects right-sided heart failure.…

    For Crackles Case Study

    With the left ventricle’s strong pumping action, blood is ejected to the rest of the body via the aorta. When the left ventricle cannot efficiently pump blood out of the ventricle into the systemic circulation, pulmonary venous blood volume and pressure build up, leading to fluid accumulation in the lung instigating left-sided heart failure. Common causes of left-sided failure comprise excessive alcohol intake, history of heart attack leading to poor left-side function, infections in the heart muscle, hypertension, hypothyroidism, heart valves that are narrow or seep out and any other disease that has injured the heart muscle. The clinical manifestations include frothy or blood-tinged cough, bilateral basilar crackles, dyspnea, orthopnea, paroxysmal nocturnal dyspnea, low oxygen saturation, having palpitations, decreased urine output, weakness, fatigue, irregular rapid pulse and weight gain. In children where left-sided heart failure may be caused by heart birth defects, symptoms may include weight loss, poor feeding and failure to…

    The patient was admitted into a small, rural hospital at 1900 for an ongoing complaint of unrelieved indigestion. The patient, 48 year old male has a history of and is presently involved with smoking. After admission into the hospital it is ruled out that the patient underwent a rule out myocardial infarction with further testing involving a cardiac catheterization to be done after admission upon a separate medical center. The patient also presents to the hospital with a history of a high-fat diet resulting in a “beer belly” and large waist circumference, and the desire to be anywhere rather than the hospital. After further testing involving a cardiac catheterization, the patient is diagnosed with coronary artery disease, which was the underlying…

    Pros And Cons Of LVAD Vs. Heart Transplants

    Every day more Doctors are turning to the LVAD ( Left Ventricular Assist Device) as an alternative to a heart transplant. Many people with heart failure are not good candidates for heart transplants and because there are not enough donated hearts, the list has to be narrowed down very carefully to receive a donor heart. The patient may not be considered a good candidate for a heart transplant if they smoke or have an alcohol abuse problem, have an infection, cancer, bad diabetes, or if all organs are not healthy. In fact, it cannot be performed at all if any of those issues are in occurrence.(Michael C. Fishbein, MD "Heart Transplant: Who needs a heart transplant")…

    Segment Elevation Heart Attack

    Non-ST Segment Elevation Heart Attack A heart attack occurs when a blood vessel on the surface of the heart (coronary artery) is blocked and interrupts blood supply to the heart muscle. This causes that area of the heart muscle to permanently scar. This blockage may be caused by cholesterol buildup (atherosclerotic plaque) within a coronary artery. The plaque cracks which creates a rough surface where blood cells attach, forming a clot. Chest discomfort that happens with exertion and goes away with rest is called angina.…

    Congestive Heart Failure Essay

    Heart failure is a syndrome with symptoms and signs caused by cardiac dysfunction, resulting in reduced longevity. Congestive heart failure has become an increasingly frequent reason for hospital admission during the last 2 decades and clearly represents a major health problem (Mosterd, A., & Hoes, A., 2007). Congestive heart failure represents a major health problem. It has been estimated that congestive heart failure afflicts nearly 4 million Americans, with 400,000 new cases each year. Congestive heart failure was listed as the principal cause for 37,400 deaths in 1988 and is thought to have been a contributing cause of another 200, 000 deaths.…

    The diagnosis of heart failure can create challenges to understanding the disease process and how choices in self-care regimen can affect ones self-care regimen. Heart failure is caused by structural and functional defects in myocardium that results in impairment of ventricular filling or the ejection of blood with the most common cause is reduced left ventricular myocardial function. Heart failure can also be the result of the dysfunction of the pericardium, myocardium, endocardium, heart valves or great vessels alone or in combination (Inamdar, & Inamdar, 2016). Nearly 90 million Americans lack the required health literacy skills to care for themselves.…

    Congestive Heart Failure Essay

    • Introduction : Congestive heart failure (CHF) is specifically known as congestive cardiac failure (CCF) in the scientific papers. The term ‘’CHF’’ describes a debilitating condition in which the heart 's function as a pump is unable to deliver an adequate amount of rich-oxygen blood to the rest of the body and the fluid builds up in the body and other organs making the heart congested. CHF results from any structural or functional cardiac disorder that weakens the pumping ability of the heart, for instance, congestion of the arteries or a general weakness of the heart muscle caused by having unhealthy life styles. CHF is classified into two types: systolic dysfunction and diastolic dysfunction. The patients who have heart failures commonly experience the symptoms like breathlessness, excessive tiredness, leg swelling, etc.…

    Cardiac Magnetic Resonance Imaging Essay

    There are several imaging options today to see the heart and its function. I will explain how MRI can be used for imaging the heart. Cardiac magnetic resonance imaging (MRI) is a noninvasive test that uses a combination of a large magnet, radiofrequencies and a computer to produce detailed images of a patient's heart as it is beating. An MRI is an effective tool for mapping the overall heart structure of patients and can use these images to search for aneurysms, tears , aorta bulging and damage caused by a heart attack, and other problems . It is derived from and based on the same basic principles as magnetic resonance imaging (MRI) but with optimization for use in the cardiovascular system.…
