WebChanges in the QT and QTc intervals in 19 patients were studied at a ventricular paced rate difference of 50 beats/min. In all patients the measured QT interval shortened as the pacing rate was increased, from a mean value of 441 ms to 380 ms (p less than 0.001), but when corrected for heart rate the QTc lengthened from a mean value of 518 ms to 575 ms.
