Different types of left ventricular hypertrophy geometry are associated with different risk of cardiovascular disease. Echocardiography with the help of electrocardiographic electrocardiographic criteria of left ventricular hypertrophy can distinguish the type of left ventricular hypertrophy geometry. The purpose of this study was to determine the role of various electrocardiographic voltages of left ventricular hypertrophy to distinguish the type of left ventricular hypertrophy geometry. Cross sectional study from June to November 2015 to 100 patients in polyclinic and inpatient cardiology of RSUP H. Adam Malik Medan. The result of left ventricular hypertrophy ECG criteria of Sokolow-Lyon was not met then obtained normal left ventricular geometry with 60% sensitivity, 72.22% specificity, and 71% accuracy. The eccentric type of eccentric left ventricular hypertrophy is obtained when the Cornel Voltage is not met, the sensitivity is 25%, specificity 71.88% and 55% accuracy. Types of concentric geometric hypertrophy when the RV6 / V5> 1 ratio is satisfied, the sensitivity is 55.56%, specificity 56.36% and 56% accuracy. The RV6 / V5> 1 ratio was not met, the concentric geometry type of hypertrophy remodeling was determined with a sensitivity of 55.56%, specificity 49.45% and 50% accuracy. The study also found the sensitivity and specificity of Sokolow-Lyon criteria for left ventricular hypertrophy with echocardiography with 72.22% sensitivity and 60.00% specificity, Cornel Voltage criteria for left ventricular hypertrophy with echocardiography with 77.78% sensitivity and 70,78% specificity %, And RV6 / V5 ratio criteria for left ventricular hypertrophy echocardiography with sensitivity of 51.11% and specificity of 70.00%. Conclusions, various left ventricular electrocardiographic criteria distinguish the type of left ventricular hypertrophy geometry. Sokolow-Lyon and Cornel Voltage sensitivity and specificity is better than the RV6 / V5 ratio.
