Key result
A proposed simple rule for QTc estimation showed good agreement with the Hodges equation in acutely ill patients, demonstrating a mean difference of -3.4 ms.
Why the study?
Existing formulae for heart rate-corrected QT interval estimation require calculators or applications, prompting the evaluation of a simpler rule for QTc estimation.
Does a simple rule for QTc estimation provide good agreement with standard formulae in patients with acute pulmonary edema?
Observational (n=104)
No
Does a simple rule for QTc estimation provide good agreement with standard formulae in patients with acute pulmonary edema?
Mean Difference: -3.4 (95% CI -9.9–3.2)
A proposed simple rule for QTc estimation shows good agreement with the Hodges formula in acutely ill patients with heart rates between 40 and 130 bpm, offering a quick alternative for QT correction without a calculator.

May support a calculator-free QTc rule in acute care; leaves open validation against other formulae and outcomes.
Neto et al. (2020) conducted an observational in Acute pulmonary edema (n=104). Simple rule for QTc estimation vs. Hodges equation was evaluated on Agreement between the simple rule and Hodges equation for QTc estimation (MD -3.4, 95% CI -9.9 to 3.2). A proposed simple rule for QTc estimation showed good agreement with the Hodges equation in acutely ill patients, demonstrating a mean difference of -3.4 ms.
