QT correction in atrial fibrillation - Measurement revisited

WebIn atrial fibrillation or flutter, the heart rate may be 100 to 175 beats per minute. Blood pressure may be normal or low. What is a normal QT interval? The normal QT interval is controversial, and multiple normal durations have been reported. In general, the normal QT interval is below 400 to 440 milliseconds (ms), or 0.4 to 0.44 seconds. WebNov 22, 2024 · If there is a U-wave, the QT interval should be determined as the intersection of the T-wave maximum slope with the isoelectric line (figure above). The QTc may be determined using a calculator (e.g. MDCalc ). QTc >~475 ms is statistically elevated (above the 99th percentile). Torsade is unusual unless QTc is >500 ms.
