Corrected QT Interval in Hypertension Seen in a Tertiary Health Institution in North Central Nigeria

Abstract

being introduced have effect on QT interval. Methodology: A retrospective study of QT corrected (QTc) was undertaken in the Jos University Teaching Hospital considering gender and presence of hypertension. Results: A total of 1004 results were analyzed, the age ranged from 18 to 70 years, 637 females (259 hypertensive, 378 non-hypertensive) and 367 males (142 hypertensive and 225 non-hypertensive). Male mean age was 49.78 ± 16.64 years and female mean age was 45.68 ± 12.20 years (P = 0.001). QTc did not correlate with age (r² 0.03). Male mean QTc was 431.57 ± 46.29 ms (hypertensive) and 427.95 ± 31.30 ms (non-hypertensive), P = 0.207. Female QTc values were 438.15 ± 35.51 ms (hypertensive) and 436.14 ± 48.13 ms (nonhypertensive), P = 0.046. Conclusions: Although QT generally gets prolonged with age poorly, female gender has a relatively higher QTc even more so when hypertensive
