Abstract Objective To investigate the diagnostic standardization of left ventricular hypertrophy by electrocardiogram(ECG).Methods With ECG network information system in Yanghu District of the Second People’s Hospital of Changzhou, retrospectively analyse ECG graphic reports from January 2012 to March 2013. Comparing ECG results with corresponding echocardiographic reports, study the diagnostic criteria of left ventricular hypertrophy(including left ventricular pachynsis and/or left ventricular enlargement) by ECG. Results The study suggests that it’s appropriate to regard left ventricular high voltage with ST-T changes as a necessary condition for the diagnosis of left ventricular hypertrophy(positive rate was 69.39% while coincidence rate was 55.68%). The coincidence rate shows a significant increase if the necessary condition is combined with left axis deviation and/or QRS≥100 ms. Conclusion Simple left ventricular hypertrophy only represents as left ventricular high voltage with ST-T changes. If left axis deviation is combined with the above representation, the incidence of left ventricular pachynsis and left ventricular enlargement may be equal. If QRS≥100 ms is combined, it mainly implies left ventricular enlargement.
