Correlation between electrical and mechanical properties of the left ventricle in patients with postinfarction ventricular tachycardia.

Background: Electroanatomical mapping allows differentiation between viable and scarred myocardium. Echocardiography is widely used to assess myocardial contractility. The relationship between electrophysiological and echocardiographic assessment of left ventricular function has not yet been well established.

[Wellens's syndrome -- the ominous T-waves].

We describe three patients with Wellens's syndrome: biphasic T-waves or deeply inverted T-waves in the precordial leads plus a history of acute coronary syndrome without serum marker abnormalities. Wellens's syndrome is due to critical stenosis of the proximal left anterior descending artery and there is a high risk for anterior wall myocardial infarction and/or sudden cardiac death within a few weeks. Early coronary angiography with subsequent PCI or CABG should be performed in these patients.

Circumferential pulmonary vein RF ablation in the treatment of atrial fibrillation: 3-year experience of one centre.

Introduction: In patients with atrial fibrillation (AF), significantly symptomatic in particular, restoring and maintaining sinus rhythm is one of treatment strategies. Considering the limited efficacy and side effects of anti-arrhythmic agents, growing hopes are attributed to the developing techniques of percutaneous ablation.

Aim: To determine the efficacy and safety of circumferential pulmonary vein ablation performed using the CARTO system in patients with paroxysmal or permanent AF.
