Fast heart rate may be emotional, tachyarrhythmia, hyperthyroidism, hypoglycemia and other reasons, physiological reasons do not need to deal with, pathologic
1. Emotional excitement: emotional excitement will cause sympathetic nerve excitation, the role of the sympathetic nerve receptors in the heart and lead to fast heart rate, strenuous exercise will also be compensated for the increase in body oxygen consumption will also speed up the heart rate, all belong to the physiological phenomenon, without special treatment, after resting, generally can be restored.
2. Tachyarrhythmia: Organic or non-organic lesions of the heart may cause heart excitation, conduction and other organizational dysfunctions, resulting in tachyarrhythmia, leading to fast heart rate. Antiarrhythmic drugs such as amiodarone, lidocaine and bisoprolol can be applied to treat the arrhythmia, which can be corrected by electric defibrillation and radiofrequency ablation if necessary.
3. Hyperthyroidism: after hyperthyroidism, a large amount of thyroid hormone is synthesized and secreted, which acts on the thyroid receptors on the heart, leading to myocardial hypermetabolism and fast heart rate. Metoprolol can be applied to rapidly reduce the heart rate, and the application of methimazole, propylthiouracil and other anti-thyroid drugs.
4. Hypoglycemia: After hypoglycemia, the lack of energy supply to the tissues, reflex excitation of sympathetic nerves leads to rapid heart rate, oral sugar cubes, intravenous injection of 50% dextrose solution to quickly and effectively reduce the heart rate.
Fast heart rate may be related to a variety of factors, it is recommended to consult a doctor for a clear diagnosis, pay attention to the use of drugs under the guidance of the physician.
