… distinguish RVOT tachycardia from VT due to ARVC. A potential source of confusion is that RVOT tachycardia, like ARVC, may be associated with right ventricular outflow dilatation. The following tests may be …
4. 心房細動における心拍数のコントロール：非薬物療法control of ventricular rate in atrial fibrillation nonpharmacologic therapy [show details]
… number of short RR intervals, which may improve symptoms by making the ventricular rate slower and more regular during AF. A potential advantage of this approach is that no catheter ablation of the AV junction …
5. 心房細動における心拍数のコントロール：薬理療法control of ventricular rate in atrial fibrillation pharmacologic therapy [show details]
… patients with heart failure due to systolic dysfunction and AF, digoxin has two potential benefits: reduction in the ventricular rate and improvement in contractility. For these reasons, digoxin was in the …
