Normal heart rate range is 60-100 beats/min. 175 beats/min may be caused by paroxysmal supraventricular tachycardia, hyperthyroidism, respiratory failure and other diseases, and the treatment needs to be directed at the primary disease.
1. Paroxysmal supraventricular tachycardia: the main manifestation is palpitation and chest tightness, and ECG examination shows more than 3 consecutive QRS waves with a frequency of 160-220 beats/min. It can be treated by stimulation of vagus nerve, medication and radiofrequency ablation.
2. Hyperthyroidism: patients with hyperthyroidism may also have tachyarrhythmia due to the increased secretion of thyroid hormone, which can be treated with medication to control the fast ventricular rate under the premise of using drugs such as propylthiouracil for the treatment of hyperthyroidism.
3. Respiratory failure: patients with respiratory failure have severe impairment of pulmonary ventilation and gas exchange function, and the body is severely lacking in oxygen, in order to meet the normal supply of oxygen, the heart rate will be compensatory acceleration. At this time, it is necessary to treat the primary disease that causes respiratory failure, and to be mask oxygen, ventilator-assisted respiration and other measures.
A sudden rapid heart rate of 175 beats per minute requires active treatment of the primary cause. If the symptoms of tachycardia appear, it is necessary to consult a doctor in time to avoid delaying the condition.
