Implication

May warrant time-of-day consideration in ECG interpretation; hypothesis-generating for adjusted references in clinical populations.

Structured PICO

Population

35 healthy male volunteers

Outcome

Diurnal changes in vital sign measurements, ECG interval durations (PQ, QRS, QTc) and R wave as well as T wave amplitudessurrogate

Significant diurnal variations exist in ECG parameters, particularly T wave amplitudes and QTc intervals, in healthy males, which should be considered when interpreting ECGs.
