Normal antihypertensive treatment, after the blood pressure drop control, the heart beat blood resistance is reduced, usually the heart rate will be better and slower, if the blood pressure drop, heart rate increase, there may be patients with cardiac function abnormality, shock, the occurrence of pulmonary embolism and other diseases may be. 1. Abnormal cardiac function: If the patient has heart failure, the weakening of the heart’s resistance to blood beat will lead to a drop in blood pressure and an increase in the reflex heart rate. It is necessary to apply drugs such as digoxin, furosemide, and amphotericin for treatment. 2. Shock: if allergy, massive blood loss, severe cardiopulmonary disease, may lead to anaphylactic shock, hemorrhagic hypovolemic shock, cardiogenic shock, which will lead to a decrease in blood pressure and an increase in heart rate, and need to be actively applied to dexamethasone and other anti-allergy, blood transfusion to replenish blood volume, and active application of cediran, furosemide, morphine, etc. in the treatment of heart failure. 3. Pulmonary embolism: after the occurrence of massive pulmonary embolism, the patient may experience a decrease in blood pressure and an increase in heart rate, which is life-threatening, and requires a ventilator if necessary, and the active application of urokinase thrombolysis, and stabilization of vital signs. If the occurrence of blood pressure decreased heart rate fast, you need to go to the hospital in time to check the cause of the disease, formal treatment.
