Szybki i wolny częstoskurcz komorowy typu torsade de pointes - charakterystyka elektrokardiograficzna

Background: Clinical value of electrocardiographic features of torsade de pointes (TdP) has not yet been well established.Aim: To compare the mode of onset and ECG characteristics of slow (s-TdP) and fast (f-TdP) episodes of TdP.Methods: 54 episodes of TdP recorded in 6 patients (5 females, one male, mean age 64.4 years) with acquired long QT syndrome were analysed. Baseline rate of TdP (V-V), ventricular rate variability (VRV), coupling interval (CI) at the onset of TdP, prematurity index (PI) and the first cycle length (FCL) were compared between 31 s-TdP
