Ventricular tachycardia Essays

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

Supraventricular Tachycardia Narrow complex tachycardias are defined by the presence in the electrocardiogram of a QRS complex with less than 120 msec duration and a heart rate more than 100 beats per minute. They are usually of supraventricular origin, though narrow complex ventricular tachycardias were rarely reported in the literature (Hayes et al, 1991). Supraventricular origin of the tachycardia means the obligatory involvement of one or more of the cardiac structures above bifurcation of

John 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

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

her, the harder she fought to get better. “I could have let being sick get me down and ruin my life, but that’s not how I want to live. I’m going to have a good life no matter how hard I have to fight for it.” Stephanie has Postural Orthostatic Tachycardia Syndrome. P.O.T.S. interrupts your bodies’ automatic functions such as blood flow, digestion, and immune system. She has been hospitalized numerous times for various sicknesses over the years, starting at four years old. Because her immune system

We as humans are constantly faced with choices and decisions which could lead us down many paths in our life. While Siddhartha is on a journey to discover who he is, he seems to learn many lessons, which in reality are merely just an epiphany to things he was taught during his childhood. Everything in life happens for a reason, and the choices we make are always a learning opportunity that we can look back on. We can look back to prevent making the same mistake twice, or in Siddhartha’s case, he

either, tachycardia (A heartbeat that is too fast - above 100 beats per minute in adults) or bradycardia (A heartbeat that is too slow - below 60 beats per minute). While most types of arrhythmia are not serious, some predispose a person to complications such as stroke or heart failure. Others may result in cardiac arrest. There are four main types of arrhythmia 1. Extra beats: Extra beats include premature atrial contractions

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 irregular rhythm. Thus

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

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

occurs when the heart can no longer cope with the metabolic demands of the body at normal venous pressure. The heart can not respond to increased body cererilee because: - Increased heart rate, which is controlled by neural and humoral - Increased ventricular contractility, secondary circulating catecholamines and autonomic control - Increase preload, mediated constriction of venous capacitance and preservation of renal intravascular volume. As the heart demands exceed normal compensatory mechanisms

Question 1: Airway: Patient’s airway is patent and protected, a lack of noisy breathing or stridor rules out partial obstruction, the ability to talk in full sentences rules out silent complete airway obstruction, and also indicates the patient is ventilating and oxygenating sufficiently (Robertson & Al-Haddad, 2013). Cardiogenic shock does not result in airway collapse, obstruction, or hypoventilation (Van Thielen & Price, 2010). High priority: monitor the patient’s level of consciousness and

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, short

causing hypoxia and cyanosis. PULMONARY ATRESIA / PULMONARY STENOSIS Pulmonary Stenosis is the narrowing at the entrance to the pulmonary artery causing right ventricular hypertrophy. Pulmonary Atresia is the severe form of pulmonary stenosis. Pathophysiology When Pulmonary Stenosis is present, resistant to blood flow cause right ventricular hypertrophy – right atrial pressure will increase – reopening of the foramen ovale, shunting of unoxygenated blood into the left atrium, systemic circulation

HD/MUH/T.197/2014) (MSc. Crit. Care & Trauma 1st year students) SUPERVISOR: Dr. EDITH TARIMO 2015. INTRODUCTION Dysrrhythmia or arrhythmia is an abnormal heart rhythm due to disturbance in heart automaticity

Fig.2. shows the sinus Tachycardia. Sinus tachycardia can be indicated by the heart rhythm which has an elevated rate of impulses originating from the sinoatrial node. The heart rate for an average adult ranges from 60–100 beats/minutes, for infants having normal heart rate of 110–150 bpm to the elderly, who have slower normal. • Rate: fast heart beat ≥ 100bpm. • Rhythm: Regular. • P waves: Consistent, normal in morphology (if no atrial disease), Upright • P–R interval: Between 0.12–0.20 seconds

Fetal circulation In the fetus, the lungs are collapsed and fluid-filled. Therefore, there is high resistance to blood flow. The placenta will act as a fetal lung and it provides oxygen for the fetus, delivers nutrients and removes wastes. The fetus is connected to the placenta by the umbilical cord. The oxygenated blood comes from placenta to the fetus through umbilical vein to the fetus’s liver. Then it moves through ductus venosus. This allows some of the blood to go to the liver. But most of

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

pressures are used to estimate end diastolic volume. Likewise, RA pressure is used to assess end diastolic volume of the RV, and PAWP is used to evaluate left ventricular preload. Afterload is the resistance to ventricular ejection and is influenced by PVR. PVR assesses the right ventricular afterload, and SVR indexed to BSA estimates left ventricular afterload (Morton & Fontaine, 2013). Contractility is not directly determined; however, stroke volume index for right and left ventricles is used to estimate

Roberts has already developed sinus tachycardia with short runs of ventricular tachycardia, ST-segment elevation, T-wave inversion, and the development of Q waves over most of the anterior V leads on his electrocardiogram. The ST-segment elevation and the T-wave inversion indicate a possible Myocardial Infarction The low serum levels of potassium due to fluid shifting back to the intracellular compartments, the myocardium excitability increases resulting in tachycardia and abnormal EKG patterns Monitor
