Echocardiography is the most accurate non-invasive procedure to evaluate the cardiac effects of systemic hypertension. It is superior to radiography and electrocardiography in detection and quantification of left ventricular hypertrophy.
A decision to initiate therapy may be based on the echocardiographic detection of left ventricular hypertrophy in borderline hypertensive patients without evidence of left ventricular hypertrophy by electrocardiogram.

Indications

Echocardiography is not a routine test. The recommended indications in hypertension are:

To guide therapeutic decision in some patients with mild or borderline hypertension.
Echocardiography is not indicated for follow-up of left ventricular hypertrophy.

Limitations

Operator dependent. Training and experience are required for precise measurements of internal chamber dimensions and wall thickness.
Cost-effectiveness is questionable.
