What should I do if my heart is beating fast?

Generally speaking, a fast heartbeat may be caused by factors such as negative emotions, hyperthyroidism, anemia, arrhythmia, or coronary atherosclerotic heart disease. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analysis is as follows:

1. Negative emotions: When experiencing states such as tension or anger, the sympathetic nervous system becomes overactive, which can easily lead to an increased heart rate. This is a normal physiological response. Typically, once emotions stabilize or stress decreases, the heart rate gradually returns to normal, so there is usually no need for excessive concern.

2. Hyperthyroidism: This condition may be related to improper diet, negative emotions, and other factors. Excessive secretion of thyroid hormones after onset can accelerate metabolism and increase excitability of the sympathetic nervous system, leading to a rapid heartbeat, often accompanied by weight loss and increased appetite. Patients are advised to take medications such as propylthiouracil tablets, carbimazole tablets, and metoprolol tartrate tablets as prescribed by their doctor.

3. Anemia: This may be associated with malnutrition, excessive blood loss, and other factors. Insufficient oxygen delivery due to reduced blood capacity can result in myocardial hypoxia, potentially causing symptoms such as rapid heartbeat, fatigue, and dizziness. Patients are advised to take medications such as sustained-release ferrous sulfate tablets, ferrous fumarate tablets, and vitamin C tablets as directed by their physician.

4. Arrhythmia: This is generally caused by factors such as electrolyte imbalances or endocrine disorders. Common symptoms include rapid heartbeat, palpitations, and chest tightness. Patients should use medications such as atropine sulfate injection, metoprolol tartrate tablets, and phenytoin sodium tablets under medical supervision to improve symptoms.

5. Coronary atherosclerotic heart disease: This is commonly associated with conditions such as diabetes and smoking. The disease can lead to myocardial ischemia, resulting in symptoms including rapid heartbeat, chest tightness, and shortness of breath. Patients are advised to strictly follow medical instructions and use medications such as atorvastatin calcium tablets, isosorbide nitrate tablets, and amlodipine and atorvastatin calcium tablets to relieve symptoms.

In daily life, patients are encouraged to maintain adequate sleep and engage in appropriate physical exercise, such as running or walking, which is beneficial for overall health.
