Occasional rapid heartbeat and panic mainly consider tachycardia, which can be divided into sinus tachycardia and ectopic tachycardia, and can be treated with medication, electrical cardioversion and radiofrequency catheter ablation under the guidance of a doctor. 1. Sinus tachycardia: Physiological sinus tachycardia should be regular, usually without treatment. Pathological sinus tachycardia can be treated on the basis of primary disease by taking beta-blockers such as metoprolol and propranolol. 2. Ectopic tachycardia: on the basis of treating the primary disease, patients can take β-blockers such as metoprolol and propranolol, calcium channel blockers such as verapamil, digitalis drugs such as digoxin, and amiodarone is preferred for patients with organic heart disease. Patients may also be treated with radiofrequency catheter ablation and electrical cardioversion. Those who experience occasional rapid heartbeat and panic with obvious symptoms should seek medical attention to avoid delay.
