Left Ventricular Hypertrophy (ECG)

Improved Essays
Diagnostic tests used in diagnosis and management
Individuals with no or only minor symptoms are often diagnosed as a result of family screening, detection of a murmur during routine examination, or the identification of an abnormal ECG. Any individual suspected of having HCM should undergo a comprehensive cardiac history and physical examination and an electrocardiogram (ECG). ECG testing is the most sensitive routinely performed diagnostic test for HCM, but the ECG abnormalities are not specific to HCM and should prompt further diagnostic evaluation. Left ventricular hypertrophy is nearly universal in symptomatic patients; however, individuals with localized hypertrophy may present with an entirely normal ECG. Typically, the ECG is deemed

The echocardiogram of an individual with HCM can reveal asymmetric left ventricular hypertrophy, systolic anterior motion of the mitral valve, early closing followed by reopening of the aortic valve, a small and hypercontractile left ventricle, and delayed relaxation and filling of the left ventricle during diastole. A clinical diagnosis of HCM is confirmed when unexplained increased left ventricular wall thickness is greater than or equal to 15mm anywhere on the left ventricular wall. A thickness of greater than or equal to 13mm of wall thickness may also be considered diagnostic when an individual has family history of …show more content…
Individuals with ECG and echocardiographic evidence of HCM should also undergo portable ECG monitoring and exercise stress testing for additional prognostic information and risk stratification. HCM must be distinguished from acquired causes of hypertrophy including hypertension, aortic stenosis, and increased wall thickness developed by highly trained athletes.
Treatment
There is no cure for hypertrophic cardiomyopathy thus treatment is focused on relieving the symptoms and decrease the risks associated with HCM. Treatment depends upon the individual’s situation but may focus on reducing the symptoms of heart failure and chest pain, removing excess muscle from the intraventricular septum in order to improve blood flow and lower the pressures in the heart, and treat abnormal heart rhythms and/or reduce the risk of sudden death.

    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.…

    Heart failure (HF) is a complex and progressive clinical syndrome that can result from any structural abnormality or functional impairment of ventricular filling or ejection of blood.1 The term “heart failure” is preferred over “congestive heart failure” because some patients may show no signs or symptoms of volume overload.1 An estimated 5.1 million Americans >20 yrs of age have HF based on NHANES 2007-2010 data.2 By 2030, projection show that the prevalence of HF will increase 25% from 2013 estimates2. It is estimated that by year 2030, the total cost of HF will increase almost 120% to $70 billion from the 2013 estimated total cost of $32 billion.2 HF incidence increases with age, rising from approximately 20 per 1000 individuals 65 to 69 years of age to >80 per 1000 individuals 65 to 69 years of age.1 Blacks have…

    Assessment of ventricular function by an echocardiogram is essential in diagnosing CHF. It is used to identify any structural abnormalities and assessment of the ejection factor to determine what type of HF: a normal ejection factor is in-between 55% to 65% of ventricular volume. A chest x-ray and a 12-lead electrocardiogram will be needed to assess any fluid in the lungs and the condition and rhythm of the heart (Hinkle and Cheever, 2015). Important lab work includes; BUN, creatinine, liver function tests, thyroid stimulating hormone, complete blood count, urinalysis, and BNP. High levels of BNP indicate high cardiac filling pressure which if the key factor in diagnosing HF.…

    Describe the pathophysiology of left-sided heart failure. The left side of the heart supplies oxygenated blood to the systemic circulation. When there is a left-sided heart failure, the heart is unable to pump enough blood to meet the body’s needs for oxygenated blood. There is also increased pressure in the atrium which in turn also causes elevated pressure in the lungs that results in pulmonary congestion and edema.…

    It is most commonly confused with hypertrophic cardiomyopathy (HCM). HCM is a disease of the heart where there's an abnormal wall thickness decreasing the size of the cavity and limiting the amount of blood it can hold and pump. It can occur with or without an obstruction. There are a couple ways of differentiating the two. LV cavity size in athletes is slightly bigger compare to HCM.…

    Congestive Heart Failure Congestive heart failure is a progressive condition in which fluid builds up around the heart and causes pumping of the heart to become more and more difficult. Heart failure (CHF) occurs when the ventricles of your heart can’t pump blood sufficiently, causing fluid to build up not only around your heart but lungs, abdomen, and liver as well. There are multiple different types of CHF, the most common being left-sided which is when the left ventricle is weakened. Along with that, there are two separate types of left-sided CHF which are known as Systolic HF, where the ventricle fails to contract correctly and Diastolic HF, where the ventricle stiffens, according to, http://www.healthline.com/health/congestive-heart-failure#Overview1.…

    Left sided failure is the most common form of heart failure. Left sided failure involves a malfunction on the left ventricle. This malfunction prevents the ventricle to fully pump the blood through the left atrium, therefore causing the blood to pool from the left ventricle into the left atrium, and into the pulmonary veins. This sequence causes the pulmonary pressure to increase and therefore leading into pulmonary congestion, and edema. Right sided heart failure causes the blood to pool in the right atrium and venous circulation.…

    • 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.…

    Heart Murmurs and its Effect on the Body System Unusual or abnormal sounds that are heard during a heartbeat are referred to as heart murmurs. Murmurs can range from very faint to very loud and sometimes sound like a whooshing or a swishing noise. Although heart murmurs can be present at time of birth they can also be developed later in life as well. Heart murmurs are not diseases but can indicate an underlying heart problem. Normal heart beats usually make a “lub-dub” type of sound which indicates the sound of the heart valves closing as the blood moves through the heart (www.mayoclinic.com).…
