Abstract:Objective To explore the clinical value of vectorcardiogram (VCG) in the diagnosis of left ventricular hypertrophy(LVH). Methods A total of 94 hypertensive patients with LVH diagnosed by VCG were enrolled in our study, and their cardiac ultrasound and related clinical data were retrospectively analyzed. They were divided into normal group and LVH group (abnormal group) according to left ventricular weight index. The VCG and related clinical indexes were compared between the two groups. Results In the abnormal group, VCG indexes are higher than those in the normal group(P<0.05); those indexes include left direction force, transverse plane QRS loop voltage, frontal plane QRS loop voltage, QRS loop maximum space vector, QRS loop starting right vector voltage, QRS loop starting right forward vector voltage, T ring abnormality, QRS loop orientation, etc. The two groups are significantly varied in clinical indexes such as the duration of hypertension and regular use of antihypertensive drugs(P<0.05). However, there is no significant difference in the complicating of diabetes between the two groups(P>0.05). Conclusion VCG indicators including QRS loop starting vector, QRS loop voltage, T ring and QRS loop orientation have diagnostic value for LVH; long course of hypertension and irregular intake of antihypertensive drugs are important clinical factors for LVH.
