The LVH medical abbreviation stands for left ventricular hypertrophy, which means the muscular wall of the heart's main pumping chamber has become thicker than usual. It most often appears on EKG reports, echocardiogram reports and cardiology notes.
LVH is usually a sign that the heart has been working harder for a long time, most often because of high blood pressure. This page explains the word parts, shows how LVH reads on test reports, and lists the conditions it is often linked to.

What the LVH medical abbreviation describes
The left ventricle is the chamber that pushes oxygen rich blood out to the body. When it has to push against high pressure for months or years, its muscle wall thickens, much like any muscle that works against resistance. That thickening is LVH.
At first the thicker wall helps the heart keep up. Over time it can become stiff, fill less easily and need more oxygen. That is why LVH is linked with a higher risk of heart failure, rhythm problems and other heart events, and why clinicians pay attention to it even when a person feels well.
LVH on an EKG versus an echo
LVH can be reported by more than one test, and they measure different things.
| Test | What it looks at | Typical wording |
|---|---|---|
| EKG | Electrical signals; tall waves can suggest a thick wall | LVH by voltage criteria |
| TTE | Ultrasound picture of wall thickness and pumping | Mild concentric LVH, normal EF |
| Cardiac MRI | Detailed images of muscle size and tissue | Asymmetric septal hypertrophy |
An EKG can hint at LVH but can also miss it or overcall it, so an echocardiogram is often ordered to confirm.
Common causes of left ventricular hypertrophy
- High blood pressure: by far the most frequent cause.
- Aortic stenosis: a narrowed valve forces the ventricle to squeeze harder.
- Hypertrophic cardiomyopathy: an inherited thickening, written as HCM.
- Athletic training: endurance and strength athletes can develop mild, usually harmless thickening.
- Kidney disease and some storage diseases: less common causes.
The cause matters because it guides what happens next, such as blood pressure control, valve evaluation or genetic counseling.
Reading a report that mentions LVH
Echo report: "Moderate concentric LVH. LVEF 60 to 65 percent. Grade 1 diastolic dysfunction." Concentric means the wall is thick all the way around. The ejection fraction shows pumping is normal, while diastolic dysfunction means the stiff wall relaxes and fills a bit slowly.
Clinic note: "HTN with LVH on echo, BP above goal." The clinician is linking the thick wall to blood pressure, which usually means blood pressure control is the focus.
Severity words like mild, moderate and severe reflect measured wall thickness, and each lab uses its own reference values.
Questions to bring to your clinician
Finding LVH on a report often leads to a conversation rather than an emergency. Helpful questions include what likely caused it in your case, whether an echocardiogram is needed to confirm it, what blood pressure target makes sense for you, and whether a repeat test is planned to see if the thickening changes. In some people, good blood pressure control over time is linked with the wall becoming less thick.
This page offers general information about a test finding. What LVH means for your own heart is best discussed with your primary care clinician or cardiologist.
Frequently asked questions
What does LVH mean on an EKG?
The phrase signals that the electrical pattern points to a thickened left ventricle, often described as LVH by voltage criteria. An echocardiogram is commonly used to check whether the wall is truly thick.
Is LVH the same as an enlarged heart?
Not exactly. LVH means the wall is thicker. An enlarged heart, or cardiomegaly, usually means the chamber or overall heart size is bigger, which can happen with or without a thick wall.
What causes LVH most often?
Long standing high blood pressure is the most common cause. Narrowed aortic valves, inherited heart muscle conditions and intense athletic training are other causes.
Can LVH get better?
In some people, treating the cause, especially high blood pressure, is linked with the wall becoming thinner over time. Your clinician can explain what is expected in your situation.
