An introduction to the analysis of ventricular tachycardia

an introduction to the analysis of ventricular tachycardia Ventricular tachycardia exhibits 4 or more ventricular ectopic beats at a hr of 150-200bpm it results from two possible mechanisms: a latent ventricular focus/ enhanced automaticity in a ventricular pacemaker.

Ventricular tachycardia occurs when the rate exceeds 100 bpm approximately 50% of patients become unconscious at the onset of ventricular tachycardia although patients in v tach may be treated with a defibrillator, not all patients in ventricular tachycardia require this level of treatment. Ventricular tachycardia was induced more frequently in patients with coronary artery disease {32%} than in any of the other groups (p ventricular. Background data evaluating repeat radiofrequency ablation (1rfa) of ventricular tachycardia (vt) are limited objective the purpose of this study was to determine the safety and outcomes of vt 1rfa in patients with structural heart disease.

Influence of clinical and procedural predictors on ventricular tachycardia ablation outcomes: an analysis from the substrate mapping and ablation in sinus rhythm to halt ventricular tachycardia trial (smash-vt. Catheter ablation for ventricular tachycardia can reduce the need for icd and is an increasingly important adjunct to arrhythmia treatment abstract and introduction in this new analysis. Ventricular tachycardia (v-tach or vt) is a type of regular and fast heart rate that arises from improper electrical activity in the ventricles of the heart.

Abstract ventricular arrhythmias arise from complex electroanatomical substrates in patients with structural heart diseasethere have been significant advancements in technologies and techniques for ventricular tachycardia catheter ablation. The one exception to the rule is an antidromic atrioventricular reentrant tachycardia (avrt), seen in wolff-parkinson white (wpw) syndrome management once the rhythm is identified, treat according to advanced cardiac life support (acls) algorithms. Ventricular tachycardia is a life threatening heart condition in which arrhythmic heart beats occur in the ventricles the two lower chambers of the heart are known as ventricles.

Ventricular tachycardia: introduction ventricular tachycardia: a condition which is characterized by a fast heart beat originates from the ventricles more detailed information about the symptoms, causes, and treatments of ventricular tachycardia is available below. Background— we investigated the impact of catheter ablation on ventricular tachycardia (vt) recurrence and survival in a large number of patients with structural heart disease treated in the setting of a dedicated multiskilled unit. 2) resetting of ventricular tachycardia occurs more frequently than termination with programmed extrastimuli and is a marker for the ability to terminate ventricular tachycardia 3) no factor could predict termination of ventricular tachycardia after resetting.

Overview this page provides an introduction to ventricular rhythms and links to training materials on this website when the ventricles handle the pacemaking role, they can be observed on ekg tracings. Ventricular arrhythmias are almost allways wide-qrs-complex arrhythmias when confronted with a wide-qrs-complex tachycardia it can be difficult to differentiate between a supraventricular tachycardia with aberrancy or ventricular tachycardia. Paroxysmal supraventricular tachycardia (psvt) is a clinical syndrome characterized by a rapid tachycardia with an abrupt onset and termination cardiomyopathy the three most common causes of psvt. A23-year-old man originally from angola presented to an outlying hospital with a 1-day history of palpitations, dyspnea, and near-syncope in the ambulance, he developed recurrent ventricular tachycardia.

  • Introduction supraventricular tachycardia (svt) is a common heart rhythm disurbance where the heart beats faster than it should this rhythm problem is usually effectively treated with medications or through a minimally-invasive surgical procedure called catheter ablation.
  • Ventricular tachycardia and ventricular fibrillation what is ventricular tachycardia the ventricles are the heart's two lower chambers blood flows from the top chambers of the heart (atria) into the ventricles, then it moves to the lungs and through the aorta to be circulated throughout the body.
  • Eiectrogram analysis to detect changes in ventricular activation indicative of ventricular tachycardia whetber bipolar or unipolar intracardiac ejectrogram analysis might be pre/erred for discriminating.

Introduction catecholaminergic polymorphic ventricular tachycardia (cpvt) is an uncommon cardiac ion channelopathy that causes sudden unexpected death (sud) of the young. Previously proposed algorithms to predict the ventricular tachycardia (vt) exit site have been based on diverse left ventricular models, but none of them identify the precise region of origin in the electroanatomic map. Keywords: ventricular tachycardia, catheter ablation, medical therapy, meta-analysis, arrhythmia introduction ventricular tachycardia (vt) is a significant contributor to morbidity and mortality among patients with structural heart disease. Introduction sustained and recurrent ventricular tachycardia (vt) presents a therapeutic challenge in patients with heart disease, with an implied overall increased morbidity and mortality.
