Lethal Dance with Dialysis – A Case of Silent Long QT Syndrome

Fatal arrhythmia is the leading cause of mortality in chronic haemodialysis patients. Long QT syndrome is responsible for polymorphic ventricular tachycardia known as Torsade de Pointes. Classically, long QT syndromes were divided into congenital and acquired; however ‘silent’ variants, in which patients remain asymptomatic until exposed to a drug or electrolyte disturbance precipitating the arrhythmia, have now been recognized.

Could Non-Linear Heart Rate Variability Analysis of Short RR Intervals Series Give Clinically Valuable Information in Heart Disease?

New analytic methods based on nonlinear system theory have been developed to characterize the nonlinear features in HR dynamics. It is known from long time series (24h ECG recordings) that patients with chronic heart failure or stable coronary heart disease have altered fractal organization in heartbeat dynamics. During such long-time series, many confounding could limit the assessment of autonomic functions.
