The role of silent ischemia, the arrhythmic substrate and the short-long sequence in the genesis of sudden cardiac death [PDF]

, 1989
To study the role of silent ischemia and the arrhythmic substrate in the genesis of sudden cardiac death, 67 patients were studied (mean age 62 ± 12 years).

Percutaneous Left Ventricular Assist Devices in Ventricular Tachycardia Ablation: Multicenter Experience

Circulation: Arrhythmia and Electrophysiology, 2014
Background—Data on relative safety, efficacy, and role of different percutaneous left ventricular assist devices for hemodynamic support during the ventricular tachycardia (VT) ablation procedure are limited.

Radiofrequency Catheter Ablation of Atrioventricular Nodal Reentrant Tachycardia: It Is Not Always As It Is Expected [PDF]

, 2004
Observation of Coincident arrhythmias is not uncommon but the co-existence of idiopathic verapamil sensitive left ventricular tachycardia (ILVT) with other arrhythmias is very rare.

Long-Term Arrhythmia-Free Survival in Patients With Severe Left Ventricular Dysfunction and No Inducible Ventricular Tachycardia After Myocardial Infarction

Circulation, 2014
Background— A negative electrophysiology study (EPS) may delineate a subgroup of patients with severely impaired left ventricular ejection fraction (LVEF) whose care can be safely managed long-term without an implantable cardioverter-defibrillator ...

Ventricular Tachycardia

JACC: Case Reports, 2020
Chronic exposure to silica is a recognized health hazard. Manifestations of pulmonary and extrapulmonary silicosis are well described. Secondary pulmonary arterial hypertension and pericardial involvement are described, but myocardial involvement has not

Just Sinus Bradycardia or Something More Serious?

Case Reports in Pediatrics, 2013
An asymptomatic 5-year-old girl presented with bradycardia during a routine well-child visit. Further evaluation revealed profound sinus bradycardia, exercise-induced bidirectional ventricular tachycardia, and supraventricular tachycardia.

Learning disentangled representation from 12-lead electrograms: application in localizing the origin of Ventricular Tachycardia [PDF]

arXiv, 2018
The increasing availability of electrocardiogram (ECG) data has motivated the use of data-driven models for automating various clinical tasks based on ECG data. The development of subject-specific models are limited by the cost and difficulty of obtaining sufficient training data for each individual.

Graph convolutional regression of cardiac depolarization from sparse endocardial maps [PDF]

arXiv, 2020
Electroanatomic mapping as routinely acquired in ablation therapy of ventricular tachycardia is the gold standard method to identify the arrhythmogenic substrate. To reduce the acquisition time and still provide maps with high spatial resolution, we propose a novel deep learning method based on graph convolutional neural networks to estimate the ...
