Ventricular tachycardia

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…

free of hypertension and other causes of increased afterload (Alberto, Radaelli, Centola 2003). Such structural changes include increased vascular stiffness (Steppan et al., 2011) and a mild increase in heart weight, reflecting some degree of left ventricular hypertrophy (Alberto, Radaelli, Centola 2003). This can lead to several diseases of the cardiovascular system including angina pectoris, heart failure and myocardial infarction. The electrical conduction system of the heart can…

which can enhance cardiac output while at the same time reducing ventricular wall stress and oxygen demand. Nitrogylycrin should be intitailly infuses at a rate 5mcg/min and then tritrated until and adequate response has been achieved (i.e. titrated every 5 minutes in 10-20 mcg/min increments with a max infusion rate of 400 mcg/min). During infusion, the HR (watch for tachycardia r/t hypotension) and BP (especially reflex tachycardia r/t hypotension-often pretreated with beta blocking agent)…

treat an issue called arrhythmias. Arrhythmias are problems with the beat of your heartrate. There are 4 different types of arrhythmias, premature which is when you get extra beats (the most common type), Supraventricular tachycardia is when your heart beats too fast, ventricular rhythm issues can halt the ventricle from pumping blood into your body (this could result in cardiac arrest), and Bradycardia is when your heart beats too slow meaning not enough blood gets to your brains sometimes…

families and the communities when it happens. The most common cause of sudden death is young athletes in the United States is hypertrophic cardiomyopathy (HCM). Exercise or sports activities may trigger a dangerous arrhythmia called ventricular tachycardia or ventricular fibrillation, which can result in death. A family history and pre screening before sport participation can help reduce the chances of sudden death from…

coronary spasm which was relieved promptly by administration of nitrates by the primary care medical professionals. The understanding of basic skills of 2D echocardiography helped us in timely intervention in 02 cases of cardiac tamponade and Left ventricular thrombus. Most of the patients who were referred were for chest pain were assessed by basic history, physical examination augmented by ECG, Cardiac enzymes , 2D echocardiography and tread mill test which were performed before retuning…

Physiology Murmurs are the product of intense blood flow across inflexible, calcified valves; faulty valves that permit reverse blood flow (regurgitation); faulty (deviant openings) in the septum, aorta, or pulmonary artery; or abnormally high velocity of blood flow through a normal structure. Supposedly blood generally flows soundlessly through the heart; yet, these conditions can generate tumultuous blood flow resulting in auscultation of swooshing or gusty sound over the precordium (Weber &…

example a 12 lead ECG to establish any signs of arrhythmias and measurement of oxygen saturation. The ECG in patients with aortic regurgitation is non-specific and may show LVH and left atrial enlargement. In acute aortic regurgitation, sinus tachycardia due to the increased sympathetic nervous tone may be the only abnormality on ECG (Hampton, 2013). The chest radiograph is also non-specific in aortic regurgitation. Cardiomegaly is present in patients with chronic aortic regurgitation. In acute…

renal and muscle tissues and cause a lactic acidosis (Mohr, 234). When those ions become affected, potassium is then affected by the decrease in overall membrane integrity, thus causing the resting membrane potential to become prolonged and cause ventricular irritability (Mohr, 234). When the muscle starts to catabolize, myoglobin is released and blocks the tubules in the kidney (Mohr, 235). Based on muscle catabolization and myoglobin being released, nephrotoxicity occurs causing kidney…

vital on the amount of fluid that needs to be replaced. It is also a good practice to determine the patients' ventricular function prior to giving fluid to know the baseline capacity and how much fluid can you give. Physical signs should also be considered in determining hypovolemia. A cold and clammy skin would indicate poor peripheral perfusion secondary to inadequate blood volume. Tachycardia will be expected to compensate for the lowering blood pressure with a narrowing pulse pressure. A…
