The likelihood of left ventricular hypertrophy and cardiac decompensation in the long term is greatly increased with LVH. The majority of cases of LVH are due to ECG changes caused by overloading of the heart due to hypertension. This situation is mainly related to the compensatory mechanism of the heart, after the emergence of hypertension, the left ventricle needs to use greater contraction force to shoot blood into the aorta, long-term maintenance of this state of the left ventricle will be hypertrophic hyperplasia, and this compensatory mechanism continues to a certain period of time, the left ventricle will be strain, and ultimately affect the cardiac function. Therefore, the left ventricular surface high voltage, should pay attention to their own blood pressure, at the same time recommended to receive further relevant examination, under the guidance of professional doctors to clarify the cause of the disease after standardized treatment.
