Indian Journal of Pharmacology is widely used and referred journal all over India. The methods used by research workers and published in the journal are therefore expected to be very clear and free from mistake of any kind.

The methods mentioned in research letter by Roy et al[1] however has serious mistakes.

1. The correct formula for QTc is:

The research letter mentions it as a simple RR interval. The root sign is missing.

2. QT dispersion is the difference between maximum and minimum QT-interval and NOT the difference between maximum and minimum heart rate (HR). The Bazett formula and calculation of QT dispersion published in IJP do not tally with those in standard books.
