Feeling uncomfortable and having a heavy heartbeat can be considered to have both physiological and pathological causes. Physiological causes are mostly seen in healthy people, especially young patients, who often have poor rest, psychological stress, exertion or often drink stimulating beverages such as strong tea, coffee, etc., and often experience symptoms of cardiac discomfort, accompanied by a rapid heartbeat. In this case, the symptoms can be relieved by paying attention to rest, avoiding exertion, changing lifestyle and removing the above triggers. Secondly, pathological causes, such as coronary heart disease, arrhythmia patients, will have heart discomfort, heavy heartbeat feeling, accompanied by weakness, dizziness symptoms. Finally, seen in patients with cardiac and cardiovascular neuroses, there will be pain in the precordial area, but the location of the pain is variable and the pain is prolonged. Sometimes the nature is even indescribable, and also such symptoms, mostly functional, do not need treatment.
