Ventricular fibrillation

It will increase oxygen demand of heart which will further activate neurohormonal response. High blood pressure increase preload and afterload which is responsible for further impairment of ventricular function. Increase in preload and afterload causes backflow of blood to lungs which is cause of pulmonary congestion. In this case study, pulmonary congestion is evident by shortness of breath and X-ray result. Pulmonary congestion is responsible…

Cardiac Arrest Heart failure is the sudden loss of heart capacity in a man who could conceivably have analyzed coronary illness. The time and method of death are surprising. It happens in a split second or not long after indications show up. Every year, more than 420,000 crisis restorative administrations surveyed out of the healing facility heart failures happen in the United States. The expression "heart attack" is regularly mistaken used to depict cardiovascular arrest.While a heart attack…

on the screen as he explained the anatomy and physiology I was observing. The progress of the angioplasty was slow and steady, but as one of the nurses was removing the wires and preparing to close the puncture sites the patient went into ventricular fibrillation. After a brief second of confusion, the cardiologist quickly began CPR as the nurses prepared to defibrillate the patient with an AED. Minutes later the patient’s heart returned to a normal…

Breakthrough in the treatment of cardiovascular disorder Myocardial Infraction Introduction: Acute Ischemic necrosis of an area of myocardium is known as myocardial infraction (Heart attack). Heart Muscle necrosis occurring as a result of critical imbalance between coronary blood supply and myocardial demand is called myocardial infraction. Suddenly myocardial loses its blood supply. In most of the patients Myocardial Infraction develops in left ventricle. [1] The main cause of myocardial…

growth signals from wall stress to increase thickness and normalize systolic pressure; this physiological condition is known as Left Ventricular Hypertrophy (LVH) because of its effect on the left ventricle which pumps oxygenated blood to the muscles. Hypertrophy of cardiac muscles becomes deleterious when the muscles can no longer beat in sync causing fibrillations or arrhythmias or when the muscles thicken to the point of constricting or obstructing blood flow.…

Cardiac arrest: the sudden loss of heart function, breathing and consciousness caused by abnormal or irregular heart rhythms (ex: ventricular fibrillation) Cardiomyopathy: a disease of the heart muscle (myocardium), may be acquired or hereditary Defibrillation: administration of a controlled electric shock to stop an extremely rapid, irregular heart beat (fibrillation) and restore heart rate to a normal rhythm. Determinants: elements that identify or determine the nature of something,…

Diagnostic Tests For Atrial Fibrillation The initial foundation of the diagnosis of AF depends on the thorough physical examination and an ECG interpretation. In the Nottingham (2010) report, he cited the American College of Cardiology/American Heart Association (ACC/AHA), the Heart Failure Society of America (HFSA), and the European Society of Cardiology (ESC) diagnostic criteria for initial diagnosis of atrial fibrillation. This includes; a thorough history and physical…

It is vital to differentiate dilated VR spaces from other cerebral pathologies such as ventricular diverticulae, cystic neoplasms, periventricular leukomalacia, parasitic cysts, cystic infarction, and mucopolysaccharidoses. Cystic neoplasms do not manifest pure CSF intensity. Parasitic cysts like neurocysticercosis usually have a small scolex…

Pros of Stun Guns For close range self-defense, nothing brings an attacker down more quickly and efficiently then with the taser gun, the intent is not to inflict pain but it is to end the confrontation without loss of life. One Means of incapacitation with a less lethal force option for incapacitating attackers with a well-placed shot. Also when you shock the perpetrators for 30 seconds allowing you to gain control and subdued the individual. Stun guns are inexpensive, often under fifty…

large R waves of the ECG complex to restore heart rhythm) (Gylys, 2003), and automatic implantable cardioverter-defibrillator (AICD) insertion (placement of a battery-powered mechanism designed to oversee and automatically correct ventricular tachycardia or fibrillation in patients at risk of heart failure) in order to prevent the need for open heart surgery (surgery done on or in an exposed heart ) (Gylys,…
