Hypertension is the major cause of left ventricular hypertrophy. While the electrocardiogram is an extremely insensitive measure of anatomic left ven- tricular hypertrophy, it provides a time-tested important marker of an adverse cardiovascular outcome. There has been a recent temporal decrease in the incidence of electrocardiographic evidence of L VH even within the hyperten- sive population; no doubt this is the result of large antihypertensive treatment experts. Anatomical evidence of left ventricular hypertrophy is best docu- mented pre-morbidly using echocardiographic techniques. It...
