The symptoms of subacromial throbbing may be caused by muscle spasms in this area, for example, if the patient does excessive exercise in this area, it may cause excessive fatigue of the rectus abdominis muscle here, and the muscle spasms may cause throbbing when the patient is at rest. Cardiovascular disease, such as cardiac hypertrophy, aortic coarctation, or arterial stenosis, may cause excessive fluctuations in this area, leading to the clinical symptom of seeing or feeling a subxiphoid process. It may be caused by gastrointestinal-related diseases, for example, when the patient has pyloric obstruction or intestinal obstruction and other diseases, there may be peristaltic waveforms of the stomach and intestines under the xiphoid process, which may lead the patient to mistakenly believe that there are symptoms of throbbing under the xiphoid process. It may be caused by physiological factors, for example, after strenuous activities, due to the heart beating vigorously, it may lead to the occurrence of obvious beating under the raphe. In addition to this, if the patient is thin or when doing backward bending movements, there is a possibility that the clinical symptoms of throbbing under the xiphoid process may occur.
