Implication

Supports sex- and rate-specific QT/U norms for ECG interpretation; extends cross-sectional data but leaves prospective validation open.

Structured PICO

Population

200 normal men and women

Outcome

Dependence of the intervals between the points at the beginning of QRS, at the instant the T wave reaches one-half of its amplitude, at the apex of T, at the end of T and at the apex of U on the sex and the heart ratesurrogate

Provides normative data on the components of Q-T and Q-U intervals, demonstrating their dependence on sex and heart rate to aid in differentiating normal from abnormal ECG findings.
