Representative Poincaré plots of a control individual and a patient with acromegaly.
Note the larger area covered by data points obtained in the acromegalic patient illustrating increased short-term variability of the QT interval. Abbreviations: QTc, corrected QT interval by Bazett formula; STVQT, short-term variability of the QT interval.
Fig 2.
Short-term beat-to-beat temporal variability of the QT interval (STVQT) in acromegalic and matched control patients.
Individual values measured in n = 30 patients in each group are presented, the blue lines indicate mean values, P<0.001.
