Is left ventricular high voltage dangerous?

Studies have found that there are many clinical causes of left ventricular high voltage, such as respiratory diseases, cardiac neurosis diseases, etc. If not treated in time, it will cause great harm to the body. Common causes include increased or abnormal heart rate, general fatigue, insomnia, etc. In addition, heart function will continue to decline. It can be seen that once this disease is discovered, you must go to a regular hospital for examination and treatment in time, otherwise the consequences are unimaginable.

1. Causes of left ventricular high voltage

1. Secondary mediating factors caused by organic diseases of the circulatory system

For example, increases in norepinephrine, angiotensin, corticosteroids, inflammatory cytokines, and aldosterone act on the myocardium, causing myocardial cell remodeling and cardiomyocyte hypertrophy; cell hypertrophy leads to an increase in the left ventricular surface area, an increase in the number of electric couples generated, and a decrease in the internal resistance of thick myocardial cells, resulting in an increase in the electric force generated by left ventricular depolarization, which is projected onto the left ventricular surface leads and an abnormally increased QRS wave amplitude.

2. Non-circulatory system organic diseases

Diseases caused by respiratory diseases, autonomic dysfunction, cardiac neurosis, and beta-receptor hyperactivity often have symptoms and signs of excessive sympathetic nerve tension, such as increased heart rate, increased arterial pulsation, increased systolic blood pressure, fatigue, insomnia, etc.

2. Clinical significance of left ventricular high voltage

1. Left ventricular high voltage is an important indicator for diagnosing left ventricular hypertrophy

At present, it is rare to see left ventricular high voltage in electrocardiogram results. Despite the increasing development of technology, electrocardiogram still plays an important role in diagnosing left ventricular hypertrophy, and left ventricular high voltage is an important indicator for diagnosing left ventricular hypertrophy.

2. Significance of left ventricular high voltage on hypertensive myocardial microvascular disease

Hypertensive patients have increased resting myocardial microcirculatory blood flow, significantly impaired myocardial microvascular reserve and non-endothelium-dependent vasodilation capacity, and significantly reduced myocardial capillary density, which worsens with the progression of the disease. Hypertensive patients with left ventricular hypertrophy have more severe myocardial microvascular function impairment than those without left ventricular hypertrophy. If hypertensive patients have combined left ventricular high voltage on the electrocardiogram, the possibility of myocardial microvascular disease should be considered.

3. Hazards of left ventricular high voltage

High left ventricular voltage may be a measurement problem due to a thin body and less fat covering the muscles in front of the heart. If you do not usually have symptoms of chest tightness, palpitations, and shortness of breath, it may be due to this reason. Another possible reason is that the heart is enlarged, resulting in reduced cardiac function, and you usually have symptoms of chest tightness and shortness of breath.
