LVH and RVH are anatomic conditions and ECGs do not determine anatomy. There are several "rules" that help evaluate for abnormally large voltages on the pediatric ECG. Most are complicated and less practical. One practical approach is: [ Evans, 2010] Abnormal Left Ventricular Large Voltage ("LVH") Use only V6 (the left most precordial lead)

Patients with hypertension and various other valvular disorders (i.e., aortic stenosis) may develop left ventricular hypertrophy which can cause ECG abnormalities that mimic cardiac ischemia. LVH leads to prolonged depolarization (increased R wave peak time) and delayed repolarization (ST & T wave abnormalities) in the lateral leads.

In the general population, left ventricular hypertrophy (LVH), either defined by echocardiographic or electrocardiogram (ECG) criteria, is strongly predictive of cardiovascular events, independent of conventional risk factors (1-3).

This thickening is called hypertrophy. Hypertrophy means growing (trophy) too much (hyper). Left ventricular hypertrophy (LVH) makes it harder for the heart to pump blood efficiently. It can result in a lack of oxygen to the heart muscle. It can also cause changes to the heart's conduction system that make it beat irregularly (arrhythmia).

ventricular hypertrophy. Ventricular hypertrophy means the walls of the ventricles are thickened. Therefore, impulses take longer to travel through and so QRS complexes appear larger on an ECG. The QRS complexes are larger in different leads, depending on whether the hypertrophy is left or right sided.

10. Defination: right ventricular hypertrophy is the enlargement of heart's right ventricle Right ventricular hypertrophy, or simply RVH, is considered to be one of the rare diseases of the heart. Unlike the left ventricle, which tends to overwork itself when it detects abnormalities, the right ventricle dilutes itself.

Patients with hypertension and various other valvular disorders (i.e., aortic stenosis) may develop left ventricular hypertrophy which can cause ECG abnormalities that mimic cardiac ischemia. LVH leads to prolonged depolarization (increased R wave peak time) and delayed repolarization (ST & T wave abnormalities) in the lateral leads.

The prognosis for left ventricular hypertrophy mainly depends on how effectively you can control your blood pressure. Since high blood pressure is the main predisposing factor for developing left ventricular hypertrophy, it is vital to take some preventing measures, such as losing some weight in case of obesity, for this it is necessary to exercise regularly, and eat a healthy diet, limiting salt.

Left ventricular hypertrophy (LVH) is an abnormal increase in the mass of the left ventricular (LV) myocardium caused by a chronic increased workload in the heart.This is most common result of the heart trying to pump blood against the high afterload, as in hypertension and aortic stenosis.Although hypertension is the most common cause of LVH, LVH can also be found in athletes and ...
