2. Hyperthyroidism: thyroid hormone has the effect of increasing the basal metabolic rate and promoting the hyperfunction of the whole body tissues. When the thyroid gland is hyperfunctional, the thyroid hormone synthesis is too much, and the cardiac muscle and other cellular functions are hyperfunctional, which results in the increase of myocardial contraction and the acceleration of the heart rate and other symptoms.
3. Arrhythmia: whether organic or non-organic heart disease, may cause heart pacing, excitation and conduction block dysfunction, the normal rhythm of the heart disappears, so the heart beats fast.
4. Hypoglycemia: long-term malnutrition in the elderly, diabetes, overdose of hypoglycemic drugs may lead to a transient decrease in blood glucose, the lack of glucose function of tissue cells, reflex excitation of the sympathetic nerves lead to panic, sweat and other symptoms.
