help relax the heart and reduce the degree of obstruction so the heart
can pump more efficiently. Beta-blockers and calcium channel blockers
slow the heart rate, decrease contractions and relax the heart muscle.
Anti-arrhythmia drugs decrease contractions to prevent abnormal rhythms
and slow the heart rate.

with the reduction of blood pressure
for left ventricular hypertrophy focuses on the underlying cause of
the condition. Depending on the cause, treatment may involve medication
high blood pressure drugs may prevent further enlargement of left
ventricle muscle tissue and may even shrink your hypertrophic muscles.
Blood pressure drugs that may reverse muscle growth include the following:
-Angiotensin-converting enzyme (ACE) inhibitors
-Angiotensin II receptor blockers (ARBs)
-Calcium channel blockers
ventricular hypertrophy is caused by aortic valve stenosis, the patient
may have surgery to remove the narrow valve and replace it with either
an artificial valve or a tissue valve from a pig, cow or human-cadaver

repaired or replaced.
cardiomyopathy is the most common type of cardiomyopathy (enlarged
Right Ventricular Dysplasia (ARVD) is a rare type of enlarged heart
that develops when muscle tissue in the right ventricle dies and is
replaced by scar tissue. Problems with the heart's electrical signal
develop causing arrhythmia. Unlike other forms of an enlarged heart,
ARVD normally develops in teenagers and young adults. It often causes
sudden cardiac death in young athletes.
athletes should be screened with two common heart tests, not just
heart tests are an echocardiogram, or ECHO, which measures
heart size and pumping function and checks for faulty heart valves,
and an electrocardiogram, or EKG, which assesses the heart's
