Background: Among patients with structural heart disease with ventricular tachycardia (VT) refractory to medical therapy and catheter ablation, cardiac stereotactic body radiotherapy (SBRT) is a paradigm-changing treatment option.

Aims: To assess the efficacy of cardiac SBRT in refractory VT by comparing the rates of VT episodes, anti-tachycardia pacing (ATP) therapies, and implantable cardioverter-defibrillator (ICD) shocks post-SBRT with pre-SBRT.

Methods: We performed a comprehensive literature search and included all clinical studies reporting outcomes on cardiac SBRT for VT.

Article Synopsis
  • The study investigates the effectiveness of standard ECG criteria for diagnosing left ventricular hypertrophy (LVH) in patients with left bundle branch block (LBBB) and finds that QRS duration is a more reliable indicator than traditional criteria.
  • Researchers included 413 adults with LBBB and compared the predictive power of QRS duration to established LVH criteria by assessing LV mass and volume through echocardiograms.
  • Results showed that QRS duration had higher diagnostic accuracy for LVH and dilation in both men and women compared to any other ECG criteria, establishing it as a better predictor in these patients.

Unconditional scene inference and generation are challenging to learn jointly with a single compositional model. Despite encouraging progress on models that extract object-centric representations ("slots") from images, unconditional generation of scenes from slots has received less attention. This is primarily because learning the multiobject relations necessary to imagine coherent scenes is difficult.

Background: Right bundle branch block (RBBB) can be benign or associated with right ventricular (RV) functional and structural abnormalities. Our aim was to evaluate QRS-T voltage-time-integral (VTI) compared to QRS duration and lead V1 R' as markers for RV abnormalities.

Methods: We included adults with an ECG demonstrating RBBB and echocardiogram obtained within 3 months of each other, between 2010 and 2020.
