Normal heart rate range is 60~100 beats/min, heart rate 160/min suggests tachycardia, the possible causes are: physiological factors, tachyarrhythmia, hyperthyroidism, the use of certain drugs, cardiac neurosis and so on.
1. Physiological factors: normal people in nervousness, anxiety, after strenuous exercise, after drinking alcohol can be accelerated heart rate phenomenon, belongs to the physiological factors, generally remove the triggering factors after a period of time heart rate can return to normal.
2. Tachyarrhythmia: This is the most common cause of tachycardia, including sinus tachycardia, atrial tachycardia, junctional tachycardia and atrial fibrillation.
3. Hyperthyroidism: the body’s metabolic rate increases when the thyroid gland is hyperfunctional, and increased sympathetic excitability will stimulate the heart to do more work, resulting in a faster heart rate and increased cardiac contraction.
4. Drugs: Certain drugs can also cause rapid heart rate, such as thyroxine, epinephrine, caffeine, digoxin and so on.
5. Cardiac neurosis: This is a functional disease caused by autonomic nervous system dysfunction, and there is no organic lesion in the heart itself. Patients may experience palpitations, accelerated heart rate, precordial discomfort, fatigue, insomnia, headache and other symptoms.
