Ventricular fibrillation Essays

no longer be perfused by blood and oxygen resulting in loss of consciousness and, without an appropriate and rapid intervention, death within minutes. Causes: The most common cause of cardiac arrest is represented by an arrhythmia called ventricular fibrillation, in which the rapid and unpredictable electrical impulses cause a flicker that prevents the ventricles the heart from pumping blood. In a person with a healthy heart, an irregular heart rhythm long-term cannot develop without an external

Vasovagal Syncope, Pediatric Syncope, commonly known as fainting or passing out, is a temporary loss of consciousness. It occurs when the blood flow to the brain is reduced. Vasovagal syncope, also called neurocardiogenic syncope, is a fainting spell in which the blood flow to the brain is reduced because of a sudden drop in heart rate and blood pressure. Vasovagal syncope occurs when the brain and the cardiovascular system (blood vessels) do not adequately communicate and respond to each other

Atrial Fibrillation Atrial Fibrillation or Afib Atrial Fibrillation (afib) is a condition in which the atria, two upper chambers of the heart, quiver (or fibrillate) to cause an irregular beat. With the quivering of the atria, blood is unable to push into the ventricles, two lower chambers of the heart, leading to decreased blood flow throughout the rest of the body. Atrial fibrillation is the most common abnormal heart rhythm, affecting an estimated 2.7 million Americans. Men are most at risk, but

ÅF is a consulting and engineering company based in Stockholm, Sweden mainly operating within the fields of energy, industry and infrastructure (ÅF, 2017). The company has its core markets in Sweden, Norway, Denmark, Finland, Switzerland and the Czech Republic. However, through the upcoming organizational restructuring, ÅF is determined to further its international expansion and become a leader in new markets. As it will be explained later, the restructure, scheduled for the upcoming year, indicates

Once stabilized, then he would return to the unit until discharge. The nurse showed the spouse where the waiting room was and how to get to the cafeteria. The patient was having a cardioversion due to paroxysmal atrial fibrillation in an attempt to correct the abnormal heart rhythm. According to the Mayo Clinic website, cardioversion is a procedure that is done to restore a normal heart rhythm in patients who have arrhythmias. It is done by sending electric shocks to the

Green blades of grass by the thousands, children all about scattered across the field, thuds of balls in the distance bouncing against lucid tan walls, as to break up the deafening chatters of young school children running about, geared up to learn anything new headed there way. There I stood in the middle of it all. Palms sweaty, heart racing, and just waiting for them to notice me. Waiting to be tortured by the pintsized terrorist soldiers ready for war. Every now and again I wondered if they knew

What is your diagnosis? A) Atrial flutter B) Atrial fibrillation C) Ventricular tachycardia D) 1st degree heart block E) Sinus bradycardia Answer: B Explanation: (Choice B) The EKG shows: an irregular rhythm (i.e. QRS complexes at an irregular interval), ventricular tachycardia, normally shaped and narrow QRS-complexes, and absent P-waves, which is indicative of atrial fibrillation. Also, the patient has symptoms and signs of Atrial fibrillation, such as: palpitations, tachycardia with an irregularly

Supraventricular tachycardias include atrial fibrillation, atrial flutter, and paroxysmal supraventricular tachycardia. This is a type of tachycardia that originates from above the ventricles, such as the atria. It is sometimes known as paroxysmal atrial tachycardia (PAT). Several types of supraventricular tachycardia are known to exist. 3. Ventricular arrhythmias: It includes Ventricular Tachycardia, Ventricular Fibrillation and Premature Ventricular Contractions. In adults and children over 15

quiver instead of contract. Atrial fibrillation may occur in the following cardiac surgery, long-standing hypotension, pulmonary embolism, COPD, electrolyte imbalances, mitral insufficiency, mitral stenosis, hyperthyroidism, infection, coronary artery disease, acute MI, pericarditis, hypoxia, and atrial septal defects. Atria fibrillation occurs most commonly in patients over 50 years of age and those who have other types of heart disease. Sometimes, atrial fibrillation occurs in

Cardiovascular agents and Dentistry It is inevitable that a dentist will encounter patients that have systemic problems. One of which will be cardiovascular complications . It is therefore important that a dentist understand these disease and know how to manage individual’s as related to the care that a dentist plans to render in relationship to the therapy protocol that their physicians have mandated. During routine procedures the use of lidocaine is indicated. It is important to know when this

Mental Health 10/26/2015 Do not Resuscitate Nurses face legal ethical dilemmas daily. Values can stay the same for decades but society is constantly evolving. As society changes, it becomes more litigious. This leaves medical professionals constantly in a balancing act to make ethical choices that will not get them sued. Nurses are held to the highest of standards by the state board of nursing and the American nursing Association (ANA) code of ethics. Each patient that a nurse will come in contact

Implication of performance measures for patients with heart failure: A Review Abstract: The strain of heart failure (HF) has become one of the cardinal public health complication, with constantly higher rates of serious morbidity and mortality. The American College of Cardiology (ACC) /American Heart Association (AHA) and the European Society of Cardiology (ESC) have developed evidence-based guidelines for the treatment of heart failure (HF) to help practitioners to ensure appropriate and consistent

amiodarone for the treatment of ventricular and supraventricular arrhythmias with good outcomes. (2, 3) This drug is a class III agent in the Vaughan Williams scheme, with class I. II and IV antiarrhytmic effects. Amiodarone produces bradycardia, prolongs myocardial action potential and delays ventricular repolarization. Due to this three pharmacological properties amiodarone prolongs the QT-interval, predisposing to torsade de pointes (TDP), a polymorphic ventricular

being common, ventricular fibrillation is much less common in children than in adults, comparatively 4-10% versus 50% in adults.13, 14 Other cardiac etiologies include coronary artery anomalies, aortic rupture, left ventricular outflow tract obstruction, mitral valve prolapse, coronary artery atherosclerosis, arrhythmogenic right ventricle cardiomyopathy, post-operative congenital heart disease, long QT syndrome, Wolff-Parkinson White syndrome, Brugada syndrome, polymorphic ventricular tachycardia

Alexander McWilliam then proposed in 1889 that sudden death in human beings is due to the heart beating irregularly or at the wrong rate. In 1899 he published a paper demonstrating his thesis that small, regular electric pulses could treat ventricular fibrillation. Thus, resulting in the first comprehensive approach to successful cardiopulmonary resuscitation Edgar H. Booth and Mark C. Lidwell in Sidney, Australia devised a portable apparatus which could deliver large shocks to the heart at regular

My goals for my second clinical were to know how to read electrocardiogram strips and to take more opportunities to talk with my patient. During clinical I learned that my patient had a history of Atrial Fibrillation and Rapid Ventricular Response. In my mind I attempted to picture how those dysrhythmias differ from the normal sinus rhythm. My patient also had family present to offer him support. I meet my goals though asking questions to my patient and his partner throughout the shift. I learned

or scarred valve cusps. The narrowed valve cusp means less blood can move out of the left atrium into the ventricle during ventricular contraction. This causes an increase in left atrium pressure which leads to decreased cardiac output (decreased volume of blood pumped out by the heart) and an increase in pressure in the pulmonary artery (Chung, Tighe, 1999). Atrial fibrillation (irregular heart beat) also occurs as a result of mitral stenosis and this can also lead to cardiac failure in serious cases

Man’s creation brought several great things to society as our world evolved. Things like tools made of stone, the wheel, and even more complicated things like electricity helped shape the world we know today. But as Mary Shelley portrays in Frankenstein, the common man's inventions are sometimes not good enough for a mid 19th century mad-scientist cooked up in a castle with dead corpses and plenty of surgical equipment. As we all know from reading the novel, the monster didn’t have the best experience

cause of SCD.16 It is also the most common inherited cardiomyopathy and has prevalence of 0.2% (1 in 500) in the general population.19 It is generally inherited in an autosomal dominant manner, with variable penetrance of the phenotype. Left ventricular hypertrophy can also be acquired, such as that seen in longstanding hypertension, however whether there is an increased risk for SCD is not well understood. Thus, the presentation of children with HCM can range from asymptomatic detected by routine

The existence of cardiomyopathy was first proposed by Rubler et al, In 1974 Framingham study showed that heart failure was more common in diabetes due to diabetes cardiomyopathy.58,59 The Framingham heart study reveals a marked in congestive heart failure, coronary artery disease and myocardial infarction in diabetes patients.60 Diastole is that phase of the of the cardiac cycle when the heart is not contracting to propel blood out (systole) to the body, brain and lungs but instead is relaxing and
