RVH specifically affects the right ventricle, which is responsible for pumping deoxygenated blood back to the lungs. Hypertrophy is a term used to describe an organ or tissue that increases in size. This increase is due to the cells in the affected area getting bigger than their normal size. In the heart, hypertrophy causes the walls of one or more of the chambers to thicken.
This is due to the cells in the area enlarging. When hypertrophy happens in the heart, the thicker heart muscle can lose elasticity over time. In the case of the right ventricle, this causes it to struggle to pump blood to the lungs for more oxygen to be retrieved. RVH is usually caused by either congenital heart conditions or high blood pressure in the lungs, which is known as pulmonary hypertension. Signs and symptoms of RVH can be difficult for a doctor to diagnose. Symptoms of RVH can include:.

Anyone experiencing these symptoms should seek medical attention immediately, as they can be signs of serious or potentially fatal heart complications. The main complications associated with RVH are caused by the unnecessary stress it places on the heart. If it is not treated, RVH can result in a weakened heart and can heighten the risk of heart failure and cardiovascular death in some people.
Doctors will begin a diagnosis with a physical examination. They will probably recommend imaging tests to look at the heart, including electrocardiograph ECG and echocardiogram, which are commonly used to diagnose RVH. The left ventricle is usually bigger than the right, so for the right ventricle to show up on an ECG test, it will usually be more pronounced. ECG tests have their drawbacks, however. The tests are often not sensitive enough to diagnose mild to moderate RVH, and may lead to misdiagnosis in these cases. Cardiac magnetic resonance imaging cMRI may be necessary as well to get a more accurate image of the heart.
Treating RVH involves treating the cause of the condition rather than the hypertrophy itself.

For instance, people who have problems with their blood pressure may require blood pressure medications and lifestyle changes. When RVH is caused by pulmonary hypertension, doctors will prescribe specific drugs to treat that condition. These medications include vasodilators or blood vessel dilators. Some drugs that are used for erectile dysfunction in men can also help open up the pulmonary arteries and may be used for RVH. Treatment also aims to reduce or stop the thickening of the walls of the right ventricle. Currently, there is no treatment to reverse the thickening of these walls completely, although ACE inhibitors have been shown to help.
Preventing right ventricular hypertrophy from getting worse is possible in many cases. Prevention methods for RVH include reducing individual risk factors and promoting a heart and lung-healthy lifestyle. Quitting smoking , eating a balanced diet, and engaging in a regular, mild to moderate exercise routine are all ways to maintain heart and lung health.
Left Ventricular Hypertrophy (LVH)

Validity of the surface electrocardiogram criteria for right ventricular hypertrophy. Journal of the American College of Cardiology , 63 7 , The typical pattern with LVH includes deviation of the ST segment in the opposite direction of the QRS complex discordance , and a typical T wave inversion pattern is present, as seen in the image here:. If the sum is greater than 28 millimeters in males or greater than 20 mm in females, LVH is present.

If the R wave is greater than 12 mm in amplitude, LVH is present. If the sum is greater than 35 mm, LVH is present.
