Key result
Frontal QRS-T angle >51 predicts a reverse dipping pattern in masked hypertensive patients.
Why the study?
The effect of reverse dipping pattern on frontal QRS-T angle in newly diagnosed masked hypertensive patients was not well characterized.
Is the frontal QRS-T angle associated with a reverse dipping pattern in newly diagnosed masked hypertensive patients?
Observational (n=244)
Is the frontal QRS-T angle associated with a reverse dipping pattern in newly diagnosed masked hypertensive patients?
Effect estimate: AUC 0.84 (95% CI 0.77-0.90)
Absolute Event Rate: 77.9% vs 32.4%
p-value: p=<0.001
The frontal QRS-T angle is significantly increased in masked hypertensive patients with a reverse dipping pattern, suggesting its potential utility as a simple marker for risk stratification.
ECG QRS-T angle may aid reverse-dipper identification in masked hypertension; leaves open prospective validation before clinical use.

Asarcıklı et al. (2022) conducted an observational in Masked hypertension (n=244). Reverse dipping pattern vs. Dipper and non-dipper patterns was evaluated on Frontal QRS-T (fQRST) angle (AUC 0.84, 95% CI 0.77-0.90, p=<0.001). A frontal QRS-T angle cutoff of 51 predicted a reverse dipping pattern in masked hypertensive patients with 83% sensitivity and 78% specificity (AUC 0.84; 95% CI 0.77-0.90; p < 0.001).
