What Are the Treatments for Right Ventricular Hypertrophy?

Ventricular hypertrophy is caused by overloading the ventricles (diastole or systole). Including ventricular hypertrophy and enlargement, ventricular hypertrophy is predominant in patients with excessive pressure load, and ventricular enlargement is predominant in patients with excessive volume load: after a long period of load, hypertrophy and enlargement are often both. The atrial wall is thin, and it generally appears enlarged regardless of the type of overload. Atrial or ventricular hypertrophy is a common consequence of organic heart disease and can be seen on the electrocardiogram when it reaches a certain level. Treatment of ventricular hypertrophy requires the identification of underlying causes and different treatments for different causes.

Causes of ventricular hypertrophy and common diseases

Mostly caused by overload of the ventricle (diastole or / and systole).

Cardiac hypertrophy is common in hypertensive left ventricular hypertrophy, congestive heart failure, anterior wall myocardial infarction, mitral regurgitation, aortic valve stenosis, hypertrophic obstructive cardiomyopathy, pulmonary hypertension, pulmonary heart disease, dilated cardiomyopathy, Endocarditis, pericardial effusion, left ventricular wall tumor, mitral valve stenosis and other diseases can also be found in athletes' hearts.

Differential diagnosis of ventricular hypertrophy

Left ventricular hypertrophy

The position of the normal left ventricle is located at the left rear of the heart, and the left ventricle wall is significantly thicker than the right ventricle. Therefore, the normal ventricular depolarization comprehensive vector shows the characteristics of the dominant left ventricle. Left ventricular hypertrophy can make the situation of left ventricular advantage more prominent.

2. Right ventricular hypertrophy

The thickness of the right ventricle wall is only 1/3 of that of the left ventricle wall. Only when the thickness of the right ventricle wall reaches a considerable degree, will the comprehensive vector be shifted from the left ventricular advantage to the right ventricular advantage, and lead to the right ventricle surface lead ( V waves in V1, aVR) increased, while S waves in the left ventricle lead (I, aVL, V5) became deeper.

3. bilateral ventricular hypertrophy

The ECG manifestations of bilateral ventricular hypertrophy are not simply the sum of the left and right ventricular abnormalities. The following situations can occur in the ECG:

(1) Approximately normal ECG: As the bilateral ventricular voltages increase at the same time, the increased depolarization vector directions reverse each other.

(2) Unilateral ventricular hypertrophy electrocardiogram: Only one ventricular hypertrophy is shown, while the other ventricular hypertrophy is obscured.

(3) Electrocardiogram of bilateral ventricular hypertrophy: It shows the characteristics of ECG in right ventricular hypertrophy (such as V1, lead R wave is dominant, right axis is skewed to the right, etc.), and some signs of left ventricular hypertrophy (such as lead V5 R / S> 1, R wave amplitude increases, etc.).

Ventricular hypertrophy

Electrocardiogram examination, the following abnormalities:

1. The myocardial fibers become thicker, the load area increases, and the voltage generated by depolarization of the myocardium increases.

2. The thickening of the ventricular wall, the enlargement of the ventricular cavity, and the low conduction function caused by the degeneration of myocardial cells make the total time course of myocardial agitation prolonged.

3. Ventricular wall hypertrophy, strain, and relative insufficiency cause changes in myocardial repolarization sequence.

Electrocardiogram and chest X-ray photography can diagnose most ventricular hypertrophy. Echocardiography has the highest accuracy.

Ventricular hypertrophy treatment principles

Treatment of ventricular hypertrophy requires the identification of underlying causes and different treatments for different causes. If ventricular hypertrophy is caused by high blood pressure, blood pressure should be controlled first.
