When tachycardia occurs, it is important to actively identify the cause of the tachycardia and actively treat the underlying disease causing the tachycardia.

If it is caused by heart failure, it is essential to actively provide anti-heart failure treatment to control the heart failure. Once the heart failure is stabilized, long-term administration of beta-blockers should be given to effectively control the heart rate. In cases of rapid arrhythmias, anti-arrhythmic drugs should be administered timely. If arrhythmias recur frequently and there are indications, radiofrequency ablation surgery can be performed. Patients with hyperthyroidism should be treated to reduce the synthesis and secretion of thyroid hormones, bringing them back to normal levels.

If the tachycardia arises from mental stress, emotional fluctuations, or exercise, no special treatment is necessary. It only requires stabilization of the tense emotions, relaxation, and proper rest; the heart rate will quickly return to normal.
