Key result
Elevated systolic blood pressure was strongly correlated with an increased incidence of left ventricular hypertrophy on electrocardiogram (r=0.98, p<0.01), while normal ECG findings decreased as blood pressure rose.

This 10-year epidemiological survey demonstrated that elevated systolic blood pressure is closely associated with the development of electrocardiographic left ventricular hypertrophy.
Haraoka et al. (1978) conducted an observational in Hypertension and Electrocardiographic Abnormalities (n=918). Elevated blood pressure vs. Normal blood pressure was evaluated on Correlation between systolic blood pressure and left ventricular hypertrophy (Minnesota Code 3) (r=0.98, p=<0.01). Elevated systolic blood pressure was strongly correlated with an increased incidence of left ventricular hypertrophy on electrocardiogram (r=0.98, p<0.01), while normal ECG findings decreased as blood pressure rose.
