What’s wrong with a fast heartbeat and a lack of energy?

A fast heartbeat and lack of energy is panic and weakness, which may be caused by physiological reasons, low blood sugar or arrhythmia.
1. Physiological reasons: nervousness, lack of exercise, often late at night, etc. can lead to panic attacks and other symptoms, which can often be improved after appropriate regular exercise and adequate rest.
2. Hypoglycemia: If the patient has not eaten for a long time, hypoglycemia can be manifested as symptoms such as panic and weakness, which may be accompanied by sweating and cold hands, and can be improved by eating high-sugar food.
3. Arrhythmia: Some arrhythmias, such as atrial fibrillation and supraventricular tachycardia, will make the heart beat faster and the peripheral circulation insufficiently filled, resulting in symptoms of panic attacks.
If the patient has repeated panic attacks, he or she should go to the hospital in time and follow the doctor’s instructions for appropriate examination and treatment.
