- There are unique advantages and disadvantages in the choice of contact mapping (CM) versus non-contact mapping (NCM) systems during ablation of right ventricular outflow tract (RVOT) arrhythmias. This study compared acute procedural success and clinical outcomes in matched patients undergoing CM ver

- Arrhythmogenic right ventricular cardiomyopathy (ARVC) is diagnosed by a complex set of clinical tests as per 2010 Task Force Criteria (TFC). Avoiding misdiagnosis is crucial to prevent sudden cardiac death as well as unnecessary implantable cardioverter-defibrillator implantations. This study aims

- 左脚後枝起原心室頻拍：基礎疾患がない物がほとんど。左脚後枝プルキンエ線維内のCaチャネル依存性組織の緩徐伝導が形成するリエントリが原因と考えられる。左脚後枝の分枝が関与するためQRSが狭め。リエントリ回路にCaチャネル依存性の組織が含まれるためベラパミルが著効し、ベラパミル感受性特発性心室頻拍とも呼ばれる。

- 鑑別：上室性頻拍＋右脚ブロック左軸偏位
- 治療：ベラパミルが有効。リエントリ回路にCa依存の部位があるため。カテーテルアブレーションでも90%以上の成功率があるとされる。
