WebMay 14, 2024 · Fridericia formula: QT C = QT / RR 1/3. 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).

WebNov 22, 2024 · Atrial flutter is distinguishable on the electrocardiogram because it is a rhythmic tachycardia with heart rates that are divisors of 300 bpm, 150 bpm being the most frequent in untreated patients (AV conduction ratio 2:1). There are no existing P waves, although atrial waves with “saw-tooth” pattern are spotted with rates around 300 bpm.

WebSep 1, 2024 · QT interval is the measurement of ventricular activity and includes ventricular depolarization and repolarization. It is measured form the beginning of QRS to the end of the T wave in the twelve‑lead electrocardiogram (ECG) [1]. Repolarization is a function of the underlying heart rate and decreases with progressive rise in ventricular rate.
