Survival of patients with a heart rate of 190 beats/min is related to the primary disease and whether resuscitation is timely. If resuscitation is timely it usually does not affect the patient’s life expectancy, and if resuscitation is not timely or is ineffective, it may lead to the patient’s death. Many diseases of the heart may cause the patient’s heart rate to be 190 beats/min. In the case of patients with sinus tachycardia, there may be some effect on the heart function, but it does not endanger the patient’s life and does not affect the patient’s life expectancy; in the case of patients with atrial fibrillation and atrial flutter, there is an effect on the patient’s pumping function, which can be recovered after drug treatment and generally does not lead to the patient’s death; in the case of patients with ventricular tachycardia, timely resuscitation does not affect the patient’s life expectancy. However, in patients with ventricular fibrillation, if the pumping function of the heart is impaired and sinus rhythm cannot be restored within 30 minutes, it will lead to the death of the patient. Patients with a heart rate of 190 beats/min should be analyzed for the primary disease and resuscitated in a timely and effective manner to avoid delaying the condition and missing the best time for treatment.
