The treatment of cardiac arrest mainly includes medication (such as the use of atropine, isoprenaline) and pacing therapy (pacemaker implantation). 1. Drug therapy: Patients with cardiac arrest may feel dizziness, blackouts, palpitations (rapid heartbeat, often accompanied by panic), fatigue, etc. Usually, the diagnosis can be confirmed by 24-hour ambulatory electrocardiogram (EKG), and anti-sluggish arrhythmia drugs, such as atropine, isoprenaline, etc. can be used. 2. Pacing therapy: For patients with symptomatic cardiac arrest, if the long-term application of antiarrhythmic drugs is not effective, pacemaker implantation can be considered, such as single-chamber pacemaker, dual-chamber pacemaker, triple-chamber pacemaker, etc. The implantation of pacemaker can correct the abnormalities through the correction of the abnormalities by 24-hour ambulatory ECG. Pacemaker implantation can be used to correct the abnormal heart rate and rhythm, and to achieve the purpose of treatment. It is recommended to go to the hospital in time, under the guidance of the doctor, complete the relevant examinations and receive standardized treatment.
