The research aims to identify the attitude of Indonesian VTS operators toward their profession. Thus, it focuses on identifying several factors that affect construction professional identity (PI) understand better reason for pursuing job. analysis is based factors, i.e., self-image, social recognition, change, competence, and expectations about profession in future. It employs a qualitative app...
Previous studies in patients with sustained ventricular tachycardia (VT) have demonstrated the efficacy of surgical and catheter-mediated ablative procedures based on activation mapping during VT. Since extensive preoperative or intraoperative mapping may be impractical due to time constraints or patient intolerance, we sought to define characteristics of the 12-lead electrocardiogram (ECG) dur...
Background. The precision and limitations of ventricular pacemapping as a method to localize the site of earliest breakthrough of ventricular tachycardia (VT) were investigated in a canine model of experimental myocardial infarction. Methods and Results. Forty-one episodes of VT induced in 10 animals were mapped using a standard grid of 64 endocardial and epicardial bipolar electrodes to determ...
BACKGROUND Recurrent ventricular tachycardia (VT) is an important cause of mortality and morbidity late after myocardial infarction. With frequent use of implantable cardioverter-defibrillators, these VTs are often poorly defined and not tolerated for mapping, factors previously viewed as relative contraindications to ablation. This observational multicenter study assessed the outcome of VT abl...
AIMS Implantable cardioverter defibrillators (ICDs) have shown to reduce all-cause mortality in heart failure patients. In SCD-HeFT study, ICDs were programmed with a detection zone of ≥ 187 b.p.m. Thus, the incidence and clinical significance of slower ventricular tachycardias (VTs) in these patients remains largely unknown, though clinically important for device selection, programming, and fo...
Majority of ventricular tachycardias (VTs) are caused by scar-related macroreentry in patients with cardiac sarcoidosis. These VTs usually exhibit the reentry circuit on electroanatomic maps. We here describe a rare case of VT that exhibits a focal activation pattern on the electroanatomic map despite reentrant VT.

Crediting loyalty points and collecting digital coupons or gift certificates are common functions in purchasing and trading transactions. These activities can be generalized using the concept of a "voucher", which is a digital representation of the right to claim goods or services. This document presents a Voucher Trading System (VTS) that circulates vouchers securely and its terminology; it li...

A 55-year-old woman with recurrent syncope and palpitation experienced polymorphic ventricular tachycardia (VT) and more than 3 monomorphic VTs with a right bundle branch block configuration as inferior, middle, and superior axis. During the pleomorphic VT, the diastolic potential (dp) was recorded at the anterolateral left ventricle. Changes in the QRS morphology were associated with the time ...
