BACKGROUND: Pathologic prolongation of QT interval is related to increased risk of arrhythmias. Changes of this parameter are influenced by many conditions, the most important is heart rate. Several formulas have been proposed for mathematical description of QT interval/heart rate relationship. The aim of this study was comparison of different QT interval correction formulas in families with congenital long QT syndrome (LQTS).METHODS: In 28 members of 6 families with LQTS occurrence bicycle ergometry testings were performed. QT and RR intervals were measured before exercise, at peak exercise and in the 1st and the 6th minute of restitution. For...

AIM: Our aim was to: 1. compare QT dispersion from routine ECG in diabetic and no-diabetic patients with congestive heart failure, 2. describe associations between QT dispersion and circadian blood (BP) pressure variation in type 2 diabetic patients with congestive heart failure (CHF).PATIENTS AND METHODS: 122 patients admitted to hospital due to CHF in the period between years 2000-2001 have been divided into 2 groups: group 1:70 patients (m: 40, f: 30, mean age 64.7 +/- 9 years) with type II diabetes mellitus (DM), group 2:52 patients (m: 28, f:24, mean age 62.5 +/- 10.9 years) without DM. Diagnosis of CHF was made clinically and proved by ECG...

Acute bleeding from upper part of gastrointestinal tract is a frequent and serious complication affecting 20 to 60% of patients with liver cirrhosis and portal hypertension. It is associated with a high death rate of 30 to 50% and a frequent relapse of bleeding occurs in up to 40% of these patients. The most recent meta-analyses have shown that bacterial infection is an independent factor in the failure of blood hemostasis and significantly influenced mortality in these patients. The authors investigated 25 patients with acute bleeding from the upper part of gastrointestinal tract due to portal hypertension in patients with liver cirrhosis. Irrespective...

The syndrome of long QT interval frequently follows to syncope or a sudden cardiac death on the basis of originated polymorphic ventricular tachycardia of the "torsade de pointes" type. The prolongation of the QT interval in the hereditary form is based on mutation of the genes responsible for the formation of sodium and potassium channels. The authors analyze the occurrence, clinical findings, therapy and genetic and electropathophysiological connections of the most frequently occurring genotype LQT1, LQT2 and LQT3 as well as the acquired forms of the syndrome of long QT interval.
