Ventricular Tachycardia in the Absence of Structural Heart Disease
Ventricular tachycardia structurally normal heart
2015/8/5
In up to 10% of patients who present with ventricular tachycardia (VT), obvious structural heart disease is not identified. In such patients, causes of ventricular arrhythmia include right ventricular...
Pattern of initiation of monomorphic ventricular tachycardia in recorded intracardiac electrograms
ventricular tachycardia implantable defibrillator intracardiac electrogram initiation pattern
2015/7/31
Background: By analyzing stored intracardiac electrograms during spontaneous monomorphic ventricular tachycardia (VT), we examined the patterns of the VT initiation in a group of patients with implant...
Multiple Arrhythmogenic Substrate for Tachycardia in a Patient with Frequent Palpitations
atrioventricular nodal reentrant tachycardia atrioventricular reentrant tachycardia atrial tachycardia accessory pathway catheter ablation
2015/7/31
We report a 26-year-old woman with frequent episodes of palpitation and dizziness. Resting electrocardiography showed no evidence of ventricular preexcitation. During electrophysiologic study, a conce...
Influence of Atrioventricular Nodal Reentrant Tachycardia Ablation on Right to Left Inter-atrial Conduction
RF ablation AVNRT inter-atrial conduction time
2015/7/31
Background: Radiofrequency (RF) catheter ablation is the procedure of choice for the potential cure of atrioventricular nodal reentrant tachycardia (AVNRT) with high success rates. We hypothesed that ...
Idiopathic Submitral Left Ventricular Aneurysm: an Unusual Substrate for Ventricular Tachycardia in Caucasians
submitral aneurysm ventricular tachycardia
2015/7/31
Annular submitral aneurysms have been rarely reported in Caucasians. They are typically diagnosed in non-white adults who present with severe mitral regurgitation, heart failure, systemic embolism, ve...
Coexistence of Atrioventricular Nodal Reentrant Tachycardia and Idiopathic Left Ventricular Outflow-Tract Tachycardia
double tachycardia left ventricular outflow tract tachycardia atrioventricular nodal reentrant tachycardia
2015/7/30
Double tachycardia is a relatively rare condition. We describe a 21 year old woman with history of frequent palpitations. In one of these episodes, she had wide complex tachycardia with right bundle b...
Distal common pathway in atrioventricular node reentrant tachycardia
AVNRT Distal common pathway Paroxysmal supraventricular tachycardia (PSVT) EPS
2009/12/25
Anotomical boundary of atrioventricular node reentrant tachycardia (AVNRT) is composed of fast and slow pathways right atrium in upper turnaround and common distal pathway in lower turnaround. We perf...
Efficacy of Adenosine for Acute Treatment of Supraventricular Tachycardia in Infants and Children
Tachycardia supraventricular Child Infant Adenosine
2009/12/7
Background: This study was done to assess the efficacy and adverse effects of the different doses of adenosine in the pediatric age group with respect to multiple patient variables.
Methods: Over a ...
