What does high left ventricular voltage on an electrocardiogram mean?

Electrocardiographic (ECG) left ventricular high voltage refers to an increase in voltage observed on the chest leads of an electrocardiogram. This finding is not a disease itself but is commonly associated with left ventricular hypertrophy caused by various underlying conditions. Some patients may be asymptomatic, while others may experience symptoms such as dizziness, headache, palpitations, or dyspnea. It is recommended to promptly visit a qualified medical institution for comprehensive evaluation and appropriate diagnostic testing to rule out cardiac disease.
