Abstract

Abstract

Objective To evaluate the application value of vectorcardiogram （VCG） in the diagnosis of left ventricular abnormalities in the early stage of hypertension. Methods The electrocardiogram （ECG）, VCG and ultrasonic cardiogram （UCG） of 76 patients with essential hypertension at the same visit or during same hospitalization period were retrospectively analyzed. The initial vector and spatial maximum vector of VCG were used as the indicators of left ventricular abnormality, as well as the interventricular septum, left ventricular posterior wall and left ventricular end-diastolic diameter of UCG. The positive detection of the two were compared; and the detection of VCG and ECG in abnormal left ventricular electrical activity was compared. Results The detection rate of VCG in left ventricular abnormality was 55.3%, which was significantly higher than that of UCG （38.2%, P < 0.05）.The positive rate of VCG in abnormal left ventricular electrical activity was 88.2%, which was significantly higher than that of ECG （71.1%, P < 0.01）. Using VCG as the standard, ECG missed diagnosis of abnormal indicators of left ventricular electrical activity: 18 T-ring abnormalities, 4 left ventricular high voltage, and 3 branch block. Conclusion VCG has certain diagnostic advantages for early left ventricular abnormality in hypertension, especially for early detection of ventricular repolarization abnormality. Combined application with UCG can improve the positive detection rate of early left ventricular abnormality.
