What medications are effective for treating heart palpitations?
I become short of breath and experience difficulty breathing after walking for a prolonged period. The hospital diagnosed me with atrial fibrillation. May I ask, which medications are most effective for treating atrial fibrillation?

Atrial fibrillation, medically known as atrial fibrillation (AFib), is a common type of arrhythmia. The treatment plan should be tailored according to the patient's specific condition, including the type, frequency, and duration of AFib, as well as the presence of other cardiovascular diseases. Drug treatment mainly includes the following categories:
1. Medications for controlling ventricular rate: commonly used beta-blockers include metoprolol tartrate tablets, bisoprolol fumarate tablets, etc., which can effectively inhibit sympathetic nervous system activity and thereby slow the heart rate.
2. Calcium channel blockers such as nifedipine tablets, amlodipine besylate tablets, etc., reduce myocardial contractility by blocking calcium ion channels in cardiac and vascular smooth muscle.
3. Anticoagulant medications: such as warfarin sodium tablets, dabigatran etexilate capsules, rivaroxaban tablets, etc., primarily used to prevent the risk of thrombus formation and stroke in patients with atrial fibrillation.
4. Traditional Chinese medicine preparations such as Wenxin Granules, Shensong Yangxin Capsules, etc., can alleviate discomfort caused by tachycardia, such as chest tightness.
It is recommended to use these medications under the guidance of a physician.
