Previous studies have indicated that the endocardium may be responsible for a large portion of ventricular tachycardia (VT) seen with reperfusion of ischemic myocardium. To evaluate the role of the Purkinje system in nonreentrant VT arising from the endocardium after reperfusion, the anterior descending coronary artery was occluded for 20 min and then reperfused in 23 dogs after instrumentation...

Joint uncertainty decoding has recently achieved promising results by using front-end uncertainty in the back-end in a mathematically consistent framework. One drawback of the method is that it relies on stereo-data or numerical algorithms, such as DPMC, which have high computational complexity and are difficult to deploy in real applications. We propose a Vector Taylor Series (VTS) approach to...

The 41st IEEE VLSI Test Symposium (VTS) was held in San Diego, CA, USA, on 24–26 April 2023. This venue the first in-person one since COVID-19 pandemic. VTS is of premier conferences focusing test, reliability, and security challenges circuits. Following same trend as prior years, arranged three days captured a set research innovative practice (IP) sessions, keynotes, panels, embedded tutorials...

We discuss a new mass matrix with specific texture zeros for the quarks. The three flavor mixing angles quarks are functions of quark masses and can be calculated. following ratios among CKM elements given by masses: |Vtd/Vts| ' q md /ms |Vub/Vcb| p mu/mc . Also we calculate two elements: |Vcb| |Vts| 2 (ms/mb ). This relation as well in good agreement experimental data. There is problem , proba...

BACKGROUND Data on outcomes after catheter ablation of ventricular tachycardia (VT) in patients with nonischemic dilated cardiomyopathy (NIDCM) are insufficient. We aimed to investigate the effects of successful catheter ablation of VT on cardiac mortality in patients with NIDCM. METHODS AND RESULTS One hundred two patients with NIDCM (86 men; mean age, 58.8±15.2 years; mean ejection fraction...

BACKGROUND Catheter ablation of ventricular tachycardia (VT) after repair of congenital heart disease can be difficult because of nonmappable VTs and complex anatomy. Insights into the relation between anatomic isthmuses identified by delineating unexcitable tissue using substrate mapping techniques and critical reentry circuit isthmuses might facilitate ablation. METHODS AND RESULTS Sinus rh...

The 10-valent pneumococcal conjugate vaccine (PCV10) has been included in Bulgarian Childhood Immunization Program since 2010. This study aimed to assess serotype distribution and antimicrobial resistance of 198 invasive and non-invasive Streptococcus pneumoniae strains that had been isolated in Bulgaria during 2011-2016 from patients with invasive (IPD) and non-invasive (NIPD) pneumococcal dis...

BACKGROUND Radiofrequency (RF) ablation of idiopathic ventricular tachycardia (VT) has been demonstrated to be highly efficacious, but the efficacy of RF ablation of VT in patients with coronary artery disease has been unknown. Therefore, the purpose of this study was to determine the feasibility of RF ablation of VT in patients with coronary artery disease. METHODS AND RESULTS Fifteen consec...

BACKGROUND Identifying the septal versus lateral site of origin of ventricular tachycardia (VT) with a right bundle-branch block (RBBB)-type pattern and an R-S ratio >1 in lead V1 is difficult with the 12-lead ECG, especially in patients with prior apical infarction. METHODS AND RESULTS We prospectively evaluated 58 patients with VT. Sixteen patients had apical infarcts (group 1), 29 had nona...

BACKGROUND The aortomitral continuity (AMC) has been described as a site of origin for ventricular tachycardias (VT) in structurally normal hearts. There is a paucity of data on the contribution of this region to VTs in patients with structural heart disease. METHODS AND RESULTS Data from 550 consecutive patients undergoing catheter ablation for VT associated with structural heart disease wer...
