Figure 8From: Accuracy of popular automatic QT Interval algorithms assessed by a 'Gold Standard' and comparison with a Novel method: computer simulation study Resultant Vector ECG Res1 with superadded noise. The superadded noise consists of 30 dB SNR white noise, 30 dB SNR mains noise and respiratory rate of 30 per minute with 0.15 amplitude modulation and 3pi/2 phase. The y axis is in millivolts and the x axis is in milliseconds.Back to article page
