Heartbeat faster than one day may be tachyarrhythmia, hyperthyroidism, anemia, pheochromocytoma and other reasons.
1. Tachyarrhythmia: Due to the abnormal function of pacing, excitation and conduction tissues caused by organic or non-organic lesions of the heart, the normal rhythm of the heart disappears and the heart rate accelerates significantly, and with the further aggravation of the lesions, the above symptoms appear.
2. Hyperthyroidism: the thyroid tissue synthesizes and secretes a large amount of thyroid hormone into the blood, which acts on the receptors on the surface of the heart, leading to hypermetabolism of cardiac muscle cells, increased contractility of the cardiac muscle and accelerated heart rate, and with the aggravation of the condition of hyperthyroidism, the heart beats faster and faster day by day.
3. Anemia: the lack of red blood cells and hemoglobin caused by various factors, tissue cell ischemia and hypoxia compensatory excitation of the sympathetic nerves, increasing the heart rate.
4. Pheochromocytoma: adrenal chromophobe secretes a large amount of adrenaline, norepinephrine and other catecholamine hormones, which act on the heart and cause the heart rate to accelerate.
A faster heart rate day by day may be related to a variety of factors, it is recommended to consult a doctor for a clear diagnosis.
