Why does my heart beat so fast sometimes?

The average person's heart beats 60-100 times per minute in a normal resting state. Sometimes the heart beats suddenly very fast. It may be due to changes in weather conditions, mood, emotions, stress, diet, etc. It may also be due to accelerated hyperactivity of the vagus nerve. If the heart rate exceeds the normal value in a short period of time, you should rule out external factors before considering whether it is a heart disease. This article explains the causes of a rapid heartbeat.

1. Category of Causes

(1) Physiological tachycardia: Physiological tachycardia is very common. Many factors can affect heart rate, such as changes in body position, physical activity, food digestion, emotional anxiety, pregnancy, excitement, fear, excitement, drinking, smoking, drinking tea, etc., which can increase heart rate. Age is also a factor; children tend to have faster heart rates.

Drug-induced

Rapid heart rate: Sympathomimetic drugs such as ephedrine and adrenaline. Parasympathetic blocking drugs such as atropine, caffeine, thyroxine, amphetamine, etc. can cause a rapid heart rate.

Pathological

Rapid heart rate: Systemic diseases such as high fever, anemia, hypoxia, infection, hyperthyroidism, pain, acute rheumatic fever, beriberi and neurosis can cause a rapid heart rate. The normal heart rate is 60-100. Pay attention to your daily health care, have a regular routine, keep warm, exercise moderately, and avoid overeating and overdrinking.

2. Diet

Eat fruits, vegetables, lean meat, soy products, etc. Avoid greasy, raw, cold, salty and spicy foods, and avoid tobacco and alcohol. People of different ages have different heart rates. The younger the age, the faster the heart rate. If the heart rate exceeds the normal range, it is called a tachycardia. The accelerated heart rate caused by illness is most common when you have a fever. For every 1°C increase in body temperature, the heart rate can increase by 10 to 15 beats per minute. Therefore, diseases that can cause fever will often result in an accelerated heart rate, but typhoid patients are an exception. The pulse of typhoid patients is relatively slow, which is called a relatively slow pulse. This is an important characteristic of typhoid. Pneumonia, asthma and other diseases affect heart function. When heart failure occurs, there will be symptoms such as rapid heart rate, rapid enlargement of the liver, rapid breathing, and blue lips. In children with severe anemia, the heart rate will also increase to meet the body's need for blood supply. A fast heart rate may also occur when taking drugs such as atropine and epinephrine. Diseases of the heart itself, such as myocarditis, pericarditis, etc., can also increase the heart rate. A fast heart rate will generally return to normal as external factors are eliminated and the disease improves (such as fever subsiding, anemia improving, and heart function returning to normal). When taking medications that can affect your heart rate, be aware of your heart rate. If your heart rate continues to be too fast, you should consult a doctor. The normal pulse rate of an adult at rest is 60-100 beats per minute, which may vary with factors such as age, gender, labor and mood. Generally, women speed up faster than men, young children speed up faster than adults, and the elderly speed up slower. It may speed up temporarily during exercise or emotional excitement, and slow down during rest and sleep. An adult's pulse rate of more than 100 beats per minute is called a tachycardia. On the contrary, a pulse less than 60 beats per minute is called a bradycardia. You can lie in bed and feel your pulse
