WebThe P wave represents the wave of depolarization that spreads from the SA node throughout the atria and is usually 0.08 to 0.10 seconds (80-100 ms) in duration. The brief isoelectric (zero voltage) period after the P wave represents the time in which the impulse is traveling within the AV node (where the conduction velocity is retarded) and the bundle of His. WebSeveral formulas have been suggested to calculate corrected QT intervals. Some of these formulas follow: Bazett's formula for calculating corrected QT duration (QTc). Bazett Formula: QTc = QT interval / √ (RR interval) Fridericia Formula: QTc = QT interval / (RR interval) 1/3 Framingham Formula: QTc = QT interval + 154 x (1 - RR interval)
