Some of the elderly heart rate 185 beats/min can be cured. Elderly heart rate 185 beats/min belongs to the obvious tachycardia, clinically seen in paroxysmal supraventricular tachycardia, atrial fibrillation, etc. Paroxysmal supraventricular tachycardia can be treated with radiofrequency ablation, and some patients can reach the standard of complete cure after surgery. Elderly patients with tachycardia may also be heart fibrillation, atrial fibrillation is mostly seen in organic heart disease, such as coronary artery disease, rheumatic heart disease, etc., which can not be completely cured. Patients with paroxysmal atrial fibrillation can be given amiodarone transrhythmia treatment, permanent atrial fibrillation can be controlled by oral metoprolol to control the ventricular rate, and anticoagulant medication is given, but it can not be completely cured. Immediate electrical cardioversion is recommended for severe arrhythmias that result in serious hemodynamic disturbances such as hypotension and loss of consciousness. A heart rate of 185 beats per minute in the elderly can be life-threatening, and immediate resuscitative treatment should be given in the hospital, following the doctor’s instructions for an appropriate treatment plan.
