People’s emotions of happiness, anger, sadness and joy will directly affect the nervous system, but also affect the whole body’s endocrine system, causing changes in the rhythm of the heartbeat. Emotions have a huge impact on the heart, anger or joy will make the sympathetic nerves excited, resulting in increased secretion of adrenaline in the body, cardiac muscle contraction force is enhanced, which can be manifested as a faster heartbeat, and even arrhythmia may occur. It can also be accompanied by increased respiration, hyperventilation, blushing, high blood pressure, numbness of the hands and other manifestations, and in severe cases, fainting, cardiac infarction, cerebral hemorrhage and other dangerous events. Emotional disorders can trigger many diseases, especially in patients with high blood pressure and heart diseases. Excessive anger or excitement, which prompts a rapid heartbeat, can lead to the aggravation of the disease and seriously jeopardize a person’s health. In daily life, people must control their emotions, so that they do not get angry or over-excited, and maintain a good state of mind. If you feel sick, you should go to the hospital in time to avoid adverse consequences.
