VENTRICULAR TACHYCARDIA Description Ventricular tachycardia is a type of Ventricular arrhythmia, or a rapid heart beat that arises from improper electrical activity of the heart presenting as a rapid heart rhythm. It starts in the bottom chambers of the heart, called the ventricles. This is a potentially life-threatening arrhythmia because it can cause low blood pressure and may lead to ventricular fibrillation, asystole, and sudden death. Causes Arrhythmias are due to problems with the…

Cardio Pulmonary Resuscitation or CPR is a very essential life saving procedure that is provided to people who experience sudden interruption in the flow of oxygen to the brain. These conditions mostly include severe drug overdose and cardiac arrest. CPR has been responsible for saving many lives over the years, and has also stopped many unfortunate and permanent brain damages from happening. One things about CPR is that it has to be provided seconds after the event has occurred. Waiting for…

Introduction Within the United Kingdom, the prominent cause of death has been coronary heart disease. Coronary heart disease is the gradual accumulation of atheroma, which ultimately obstructs the heart from oxygenated blood as the blood vessels become narrow. The likelihood of having coronary heart disease is associated with numerous risk factors, ranging from smoking to ethnic background (NHS Choices, 2014). However, this essay will only focus on the aspects of psychosocial and behavioural or…

The importance of tightly regulating plasma volume is to see how much water can a person excrete, and how the total amount of blood volume has a direct effect on plasma osmolarity. As a result, plasma volume has a direct effect on the blood pressure. Basically, when the blood contains low amount of water, it can result in decrease in plasma volume, and increases in serum osmolality which led to blood having increased viscosity (Evans 1. et al. 1506). Additionally, the plasma volume results in…

Health Effects of Oxytocin Properties of Oxytocin Oxytocin is a peptide hormone made up of nine amino acids. Oxytocin is produced by pituitary gland in the brain to carry out different physiological and psychological functions in the body like child birth, breastfeeding, mother infant bonding and social behavior. Oxytocin is also referred as love hormone, cuddle hormone or bonding hormone because it develops feelings of affection, trust, and attachment among people. It reduces the negativities…

Ischemia is a state of tissue oxygen deprivation accompanied by a reduced washout of the resulting metabolites (1). Reperfusion is the restoration of blood flow to the ischemic tissue. Despite the unequivocal benefit of reperfusion of blood to an ischemic tissue, reperfusion itself can elicit a cascade of harmful reactions that injure tissue(2). Studies have shown that renal ischemia - reperfusion injury in addition to kidney tissue, will also be affected distant organs such as the brain (3),…

Case Study #3 1. Based on my understanding of the cardiovascular system, a blood clot is a gel that consists of the formed elements of blood trapped in a network of insoluble protein fibers (Tortora,2014, p.335). How clotting is formed when a series of chemical reactions that culminates in the formation of fibrin threads (Tortora,2014, p.335). When blood is easily clots it’s called thrombosis, a thrombosis is a formation of a clot in an unbroken blood vessel, usually in a vein (Tortora,2014,…

the left side and less likely on the right, can happen on both sides at same time, if this happens it normally starts with left and moves to right. The causes of this condition are from other cardiovascular problems, such as, hypertension, coronary artery disease, and various valve conditions. Non-heart related conditions can cause CHF as well. In early stages might not notice any changes in health but as it gets worse you notice your body changing. Symptoms are, fatigue, swelling, gaining…

The heart is considered the “engine of life” through its ability to rhythmically pump oxygen rich blood throughout the body to supply life. Unfortunately, this vital organ is vulnerable to damage through actions of everyday life ranging from smoking, diet, physical inactivity, and consumption of alcohol. Damage to the heart results in heart disease, also known as cardiovascular disease. Because of the vast complexity of the heart, heart disease branches off into various categories including…
