P Wave Ananysis In Asymptomatic Healthy Adult Nigerian Students: A Preliminary Study

Abstract

The P wave amplitude and duration were measured and analyzed in the 12-lead ECG in a hundred and nine subjects aged between 19 and 30 years. The mean P wave duration was 0.07 ± 0.02 sec. Significant correlation was found between P wave duration and amplitude and various anthropometric measurements. Prediction equation was derived for the mean P wave voltage and the systolic blood pressure. The study has demonstrated the normal range for the P wave duration and amplitude. It thus provides a reference guide for the quantitative interpretations of the P waves of healthy adult Nigerians in Jos.

Key words: Electrocardiogram (ECG), P wave duration, P. wave amplitude, prediction equation, asymptomatic.
