Fast heartbeat after meals

Introduction There are two kinds of nerves that control heartbeat and contraction: sympathetic and parasympathetic. In general, the sympathetic nerves speed up the heart rate and strengthen the contraction, and the parasympathetic nerves are the opposite. When people are excited, they are mainly sympathetic and excited, and the parasympathetic nerves are mainly excited during nighttime sleep. In the case of the body, these two kinds of nerves exist at the same time and are mutually restricted, but in some cases, they are mainly one. The nerve distribution of the gastrointestinal tract is mainly parasympathetic (mainly vagus nerve). After eating, the parasympathetic nerve is excited. For the heart, the heart rate is slowed down and the contraction is weakened, but the sympathetic nerve of the heart will have a reflective change. It is possible that the sympathetic nerves are hyperactive, which can cause the heartbeat to accelerate and contraction to strengthen, and the heartbeat can be obvious. - Heart palpitations. This is not a disease, but a normal reaction, seen in many normal people. If the patient's condition is frequent, it is recommended to check the ECG and so on. Actively find the cause and symptomatic treatment.

Cause

After eating or satiety, the gastrointestinal tract is digesting food, and the gastrointestinal tract peristalsis is increased, so the blood flowing into the gastrointestinal tract is increased, and the increased blood is extracted from other parts of the body. Of course, some of them are extracted from the share of the supply of the heart, which will reduce the amount of blood supply to the heart. The heart will increase the beating of the heart in order to maintain normal work.

an examination

Physical examination

After asking about the medical history, you should have a targeted physical examination. If the patient is suspected of having a structural heart disease, it is important to check whether the heart has pathological signs, such as whether there is heart murmur, heart enlargement and heart rhythm change, etc., whether there is blood pressure, pulse pressure, water pulse, etc. The general condition of patients with cardiac signs, such as mental state, body temperature, anemia, hyperhidrosis and goiter, should also be carefully checked to avoid omissions.

2. Laboratory examination

If you suspect that the patient has diseases such as hyperthyroidism, hypoglycemia or pheochromocytoma, you can carry out related laboratory tests, such as measuring serum T3, T4 thyroid iodine absorption rate, blood sugar, blood, urine catecholamines. When suspicion of anemia. Blood tests can be performed if necessary. Bone marrow puncture can be performed to check the bone marrow smear to further clarify the cause.

3. Device inspection

The most important thing in the examination of the device is the electrocardiogram examination, and it is convenient and quick for patients without painful ECG. It can not only find out whether there is arrhythmia or the nature of arrhythmia. If there is no abnormality in the electrocardiogram at rest, the patient can exercise properly or perform 24-hour Holter monitoring. For patients with suspected organic heart disease, to further clarify the cause, cardiac Doppler ultrasonography can be performed to understand the heart disease. Nature and severity.

Differential diagnosis

Differential diagnosis of heartbeat after meal:

1, the heartbeat is very chaotic: the heartbeat is very chaotic refers to the heartbeat is fast or slow, beyond the general range. Cardiac tachycardia, bradycardia, or arrhythmia caused by abnormalities in the heart or conduction disorders. Stress, a lot of smoking, drinking, drinking tea or coffee, excessive fatigue, severe insomnia and other factors that are often arrhythmia. Arrhythmias are particularly common in patients with heart disease and often occur during anesthesia, surgery, or surgery.

2, heart palpitations with abnormal heart rate: palpitations is a sense of discomfort or palpitation of the heart beat. When the heart rate is increased, it is felt that the heart beats discomfort, and when the heart rate is slow, it feels powerful. When you have a heart palpitations, your heart rate can be fast, slow, or have arrhythmia. People with normal heart rate and heart rhythm can also have heart.

3, tachycardia: adult heart rate more than 100 beats / min, called heart skip speed.
