Patient discomfort following catheter ablation and rhythm device surgery.

Aims: Proper management of post-interventional pain relieves unwarranted patient distress and enhances patient satisfaction. There have been only a limited number of investigations into patient discomfort following electrophysiological interventions. This study aims to quantify pain after interventional procedures, including ablation of atrial fibrillation (AF) or ventricular tachycardia (VT), as well as implant or explant of pacemakers or implantable cardioverter defibrillators.

Associations of hemodynamic load and ventricular repolarization in patients with newly diagnosed essential hypertension: a long-term follow-up study.

The evolution of QT interval and its dispersion (QTd) were studied in 135 newly diagnosed nondiabetic patients, as well as the relationship between changes of these left ventricular (LV) repolarization parameters with blood pressure (BP) and LV mass changes, which were prospectively studied for a median period of 3.8 years. At baseline and at last follow-up visit, all patients underwent ambulatory BP monitoring, echocardiographic assessment, and 12-lead electrocardiography.
