BACKGROUND Carbon monoxide (CO) poisoning are serious health problems, and effect of reducing the blood's oxygen carrying capacity. Deaths due to CO poisoning are mostly related to myocardial injury and central nervous system pathologies. AIM The objective of this study was to determine the relationship between carbon monoxide intoxication, QT dispersion, and cardiac markers. MATERIALS AND ...

Electrophysiological abnormalities in cirrhosis, such as the prolongation of the QT interval, are associated with higher risk of ventricular arrhythmias. Holter monitoring offers a full picture of these during 24 hour. Our study aimed to evaluate the extent of the QT interval prolongation, identify etiological and biochemical elements linked with it, and investigate the correlation with ventric...

Ketoconazole is listed among drugs that prolong QT interval and may increase the risk of torsade de pointes, a severe ventricular arrhythmia. This compound has recently been approved for treatment of Cushing's syndrome, a severe endocrine disorder. These patients harbour several risk factors for prolonged QT interval, for example hypokalaemia and left ventricular hypertrophy, but no study has e...

BACKGROUND Cardiac ion channelopathies are responsible for an ever-increasing number and diversity of familial cardiac arrhythmia syndromes. We describe a new clinical entity that consists of an ST-segment elevation in the right precordial ECG leads, a shorter-than-normal QT interval, and a history of sudden cardiac death. METHODS AND RESULTS Eighty-two consecutive probands with Brugada syndr...
