Ventricular fibrillation

Cardiac Dysrhythmias: Ventricular Fibrillation According to Brunner et al., the most common dysrhythmia in patients with cardiac arrest is ventricular fibrillation, which is rapid, disorganized ventricular rhythm that causes ineffective quivering of the ventricles. No atrial activity is seen on the ECG. The following characteristics that constitute ventricular fibrillation are, ventricular rate is greater than 300 beats per minute. Ventricular rhythm is extremely irregular and without a specific

Ventricular fibrillation (VF) is a life-threatening condition in which the signaling in the ventricles of the hearts is no longer coordinated. The loss of this coordinated signaling causes rapid, random and chaotic signaling leading to spasms of the ventricular walls. During VF, blood is not being circulated to the brains and the rest of the body and is therefore deprived of oxygen. This condition can be reversed by using a defibrillator, which sends an electric discharge of direct current to the

INTRODUCTION: Methods to identify appropriate treatments for the various stages of ventricular fibrillation (VF) involve differentiating groups of subjects who will respond to defibrillation with return of spontaneous circulation (ROSC) and those who require other therapies (e.g., CPR, drugs) prior to defibrillation. The use of quantitative waveform measures (QWM) which measure the frequency and fractal dimension of the VF electrocardiogram have shown success in predicting response to defibrillatory

the extraordinary complexity of the human body has its flaws, for some heart rates are not always steady but rather rapid with erratic electrical pulses. An example of a dangerous flaw that could occur within the human body is Ventricular Fibrillation. Ventricular Fibrillation is the name given to the condition when the pumping chambers in your heart quiver uselessly instead of pumping blood which causes cardiac arrest. When the heart’s electrical activity becomes

If Ventricular Fibrillation/Tachycardia continues despite 3 sequential defibrillation shocks, external cardiac massage should commence. d. If patient has open chest, careful external cardiac massage should be performed over packed gauze and effectiveness should be

This paper will be going over a scenario involving a real patient and what things could have been

right precordial leads and associated with the highest level of risk for development of malignant arrhythmias.Type 3 is often associated with IVF storms. (21) Short-QT syndrome is described as a disorder characterized by abbreviated QT interval, ventricular and atrial arrhythmias,and sudden cardiac death (22) Recent studies supported an association between short QT syndrome and early repolarization. The aim of this study was to study the prevalence of ER and its relationship with the QTc interval in

shock) to an afflicted heart in order to carry out defibrillation. Defibrillation is achieved through an electric shock to the heart which helps to re-establish normal rhythms in a heart having dangerous arrhythmia (abnormal heart rhythm), ventricular fibrillation (heart beats with rapid, erratic electrical impulses) or in cardiac arrest. The most used type of defibrillator in the recent world is AEDs. Automated external defibrillators (AEDs) are small portable, lightweight devices that use electrodes

Tachycardia (SVT): SVTs are not more common in athletes than in the general population of a similar age distribution, with the possible exception of atrial fibrillation (AF). Treatment of these SVTs with catheter ablation is likely to achieve a permanent cure and, in general, is preferable to lifelong therapy with pharmacological agents. Atrial Fibrillation: Athletes with AF should undergo a work-up that includes thyroid function tests, queries for drug use, ECG, and echocardiogram. Athletes with low-risk

Complications can arise during device implantation, such as infections or during extraction [32] [33]. Incorrect ventricular excitation can result in an asynchronous activation of the cardiac muscle [34], which is a poor substitute for the normal sinus rhythm, which could lead to increased incidence of AF and heart failure in the future [35].
