High voltage in the left ventricle is described by ECG, which may be physiological hypertrophy, pseudo abnormality, and generally has no effect on the heart; pathological hypertrophy may lead to abnormal diastolic function of the heart, cardiac arrhythmia and so on.
1. No effect: some people with thin body size and thin chest wall may have ECG report of high voltage without myocardial hypertrophy as pseudo abnormality, which has no effect on the heart; some people with regular physical exercise may have physiological hypertrophy of the heart, which has no effect on the heart if there is no obvious clinical symptom.
2. Have an effect: some patients may have hypertension, hypertrophic cardiomyopathy, aortic stenosis and other diseases, resulting in left ventricular hypertrophy. Due to the hypertrophy of the ventricular muscle, it will lead to a decrease in the diastolic function of the heart, and diastolic cardiac insufficiency, and it may also lead to ventricular tachycardia, ventricular fibrillation, ventricular premature beats and other cardiac arrhythmias.
When high voltage in the left ventricle is detected, it is recommended to consult a doctor in time to clarify the cause and treat it as early as possible.
