Objective: The objective of this study was to examine the prevalence and pattern of intraventricular conduction blocks in adult Nigerians with newly diagnosed essential hypertension and to determine the relationship between microalbuminuria and intraventricular conduction blocks. Methods: It was a cross-sectional study with nested case control. Ninety six patients were consecutively enrolled and compared with age- and sex-matched ninety six healthy normotensive individuals. Pre-tested questionnaire was used for data collection. The data collected was doubly entry into SPSS 20.0 software and analysed. P value < 0.05 was accepted as significance. Results: There were 52 (54.2%) male and 46 (45.8%) female hypertensive patients. Twenty one patients (21.9%) had intraventricular conduction blocks compared with 4 (4.2%) among the normotensive controls (21.9% versus 4.2%, P = 0.001) and left anterior fascicular block was the most frequent (38.1%). The prevalence of microalbuminuria was 32.3% in the hypertensive patients. Intraventricular blocks were significantly more common in hypertensive patients with microalbuminuria than in those without it (32.3% versus 16.9%, P=0.01). Conclusion: This study reveals that there is a high prevalence of intraventricular conduction blocks in adult Nigerians with newly diagnosed essential hypertension and left anterior fascicular block is the most common type. It also shows that the subset of hypertensive patients with microalbuminuria is more likely to have intraventricular blocks than those without it.
