Ventricular fibrillation

Stroke volume is the difference in ventricular end diastolic volume (EDV) and end systolic volume (ESV). Some of the factors that influence SV and thus CO include contractility, preload and afterload. Afterload is the resistance felt by the ventricle during systole. An increase in afterload…

regurgitation (MR) which affects 200,000 people every year in the US alone. The Mitral valve is a key site of failure due to its location between the left atrium and left ventricle, it prevents the backflow of oxygenated blood into the atrium during ventricular systole and constantly experiences high pressures. MR is the backflow of blood into the atrium and pulmonary veins due to the partial or complete mitral valve failure. This failure is rated on a scale from 0 to 4, 4 being severe. MR can…

What is the SCA? What Can Cause your heart to stop beating? We hear a lot about heart disease and its causes that considered from our wrong daily habits. Most of them can be treated and coexist with, but there is a disease that affects the heart and makes it stop pumping blood through the body without any introductions or previous symptoms which would lead to the death of the injured person on the spot. This disease, known as sudden cardiac arrest (SCA) • What is the sudden cardiac arrest?…

Heart failure is when the heart is too weak to pump blood efficiently, and cannot provide proper cardiac output that the body needs to maintain the body’s metabolic needs. Also, heart failure is when the heart muscle has become damaged and cannot contract and pump blood up and through the valves and out through both sides of the heart or the heart muscle has become too stiff. This process mainly relates to the heart muscles of the ventricle chambers. The ventricles are the main problem within…

coronary arteries. Hence, administering glyceryl trinitrate (GTN) to john has allowed potent vasodilation of coronary arteries to increase the blood flow. Their principle benefit follows from a reduction in venous return which reduces the left ventricular work. Aspirin as an antiplatelet drug decrease platelet aggregation and may inhibit further thrombus formation in arterial circulation, including the coronary vessels. Administration of aspirin will prevent John from recurrent…

combining the medication might have caused Mr. B. to become over sedated. Over sedation can result in decreased oxygen level and lower blood pressures (58/30 and 79%) as in the scenario. The potential for life threatening conditions such as the ventricular fibrillation and respiratory distress or arrest can result from over sedation, as…

atherosclerotic plaque. Embolic ischemic strokes are caused by an embolus occluding a blood vessel. Finally, hypoxic ischemic strokes are due to hypoxemia or cerebral hypoperfusion. Other causes of ischemic stroke include atrial fibrillation, sickle cell disease and ventricular tachycardia. The pathophysiology of an ischemic stroke first involves a decrease in oxygen, glucose and other nutrients due to ischemia. Due to decreased oxygen, the normal process of oxidative phosphorylation does not…

“Fluanxol”  Introduction : • History and background : - Fluanxol is a thioxanthene derivative which contains flupentixol as active substances. It belongs to group of medicines known as antidepressants drugs which act on nerve pathway in specific areas of the brain and help in correcting some chemical imbalances that cause the symptoms of this illness. - Its International Non-proprietary Name (INN) is flupentixol , but its British Approved Name (BAN) is flupenthixol and it is known in the market…

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…

My role as Geriatric Psychiatrist, providing care in the general hospital, also enables me to see other aspects of our health care system. Recently, our hospital announced the closing of Geriatric Assessment Clinic due to it’s financial return or lack there of. This is the place where we could refer the Geriatric patients with complex issues that required the team of different disciplines to figure out how to best care for those particular patients. There is no incentive to provide care for the…
