Electrocardiographic Detection of Left Ventricular Hypertrophy by the New “sai” Criteria

Electrocardiogram (ECG)is widely used for detection of left ventricular hypertrophy (LVH). For the detection of LVH several different criteria have been used. These criteria have different sensitivity and selectivity, which widely varies from 22% to 54% sensitivity and 100%to 85%specificity respectively. Different LVH criteria has different results of LVH. The aim of the present study was to determine most accurate diagnostic relation of LVH with QRS-complex and T-wave of ECG by using new proposed “SAI” criteria. In sai criteria we relate QRS and T-wave abnormality with LVH. Fifty clinically diagnosed patients of LVH were included in this study. These were followed by echocardiography as a gold test. In conclusion; sai criteria for LVH may be the most accurate for the detection of LVH by 12-lead ECG. Limitations: subjects are from one racial and no other parameters were considered. Research work has been in progress for more generalized results.
