Web14 de mai. de 2024 · Framingham formula: QT C = QT + 0.154 (1 – RR) Hodges formula: QT C = QT + 1.75 (heart rate – 60) Note: The RR interval is given in seconds (RR interval = 60 / heart rate). Bazett and Fridericia are logarithmic corrections whereas Hodges and Framingham are linear correction formulae. Henry Cuthbert Bazett derived his formula in … In electrocardiography, the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120 and 200 ms in duration. The PR interval is sometimes termed the PQ interval.
