Cardiac ablation is not a major surgery. Radiofrequency ablation is a treatment for all types of arrhythmias, and is very effective in treating rapid atrial fibrillation, ventricular tachycardia, and supraventricular tachycardia. For patients whose ventricular rate is not controlled by medications, radiofrequency ablation can be actively performed. Absolute bed rest should be observed within 24 hours after surgery, and ECG and ambulatory ECG should be reviewed in a timely manner. If necessary, anti-platelet aggregation drugs such as aspirin enteric tablets and clopidogrel hydrogen sulfate should be taken to prevent thrombosis, and oral medications such as metoprolol tartrate should be taken to control the heart rate to prevent rebound elevation of the heart rate or induce premature atrial or ventricular contractions.
