WebLeft Ventricular Hypertrophy (LVH) ECG Review Learn the Heart - Healio The commonly used method to diagnose LVH is echocardiography, with which the thickness of the muscle of the heart can be measured. The electrocardiogram (ECG) often shows signs of increased voltage from the heart in individuals with LVH, so this is often used as a screening test to determine who should undergo further testing.
WebFeb 24, 2024 · Summary. Electrocardiography is an important diagnostic tool in cardiology. External electrodes are used to measure the electrical conduction signals of the heart and record them as lines on graph paper (i.e., an electrocardiogram; ECG). The interpretation of the amplitude and duration of these lines allows for the assessment of normal cardiac ...

It is used to detect left ventricular hypertrophy (LVH) using an ECG. In a case of LVH, the amplitude of the S wave is increased in right oriented leads (like V1) and that of the R wave is increased in left oriented leads (like V5 and V6).
