Predictors of recurrence in patients without non‐inducibility of ventricular tachycardia at the end of ablation Open
Background Ventricular tachycardia (VT) non‐inducibility at the end of ablation is associated with a less likely VT recurrence. However, it is not clear whether we should use VT non‐inducibility as a routine end point of VT ablation. The a…

Ventricular arrhythmia events in heart failure patients with cardiac resynchronization therapy with or without a defibrillator for primary prevention Open
Background It is uncertain whether cardiac resynchronization therapy with a defibrillator (CRT‐D) provides better survival benefits than a CRT‐pacemaker (CRT‐P) in heart failure patients with a reduced ejection fraction (≦35%, HFrEF) treat…

MODEL TESTS ON EFFECTIVENESS OF EPS FOUNDATION AS A COUNTERMEASURE AGAINST INSUFFICIENT COMPACTION AROUND BURIED PIPE Open
管埋設時の管底側部は,狭窄で作業スペースが限られることから,十分な品質の埋戻しや締固めを確保することが困難な場合がある.不十分な埋戻し・締固めは,管に不測の変形や応力集中を引き起こす可能性がある.本研究では,管底側部の埋戻しの代わりに,土木材料として実績の多いEPSを管基礎として設置する方法を提案し,その有効性について,ポリエチレン管(内径300 mm)を用いた埋設模型実験により検討した.その結果,EPSの形状によっては,管底や管とEPSの接点でひずみが集中する傾向にあるも…
