The subxiphoid pulsation may be caused by the following reasons: 1. This condition may be caused by physiological factors, such as the intense beating of the heart after the patient’s strenuous activities, which may lead to a significant pulsation in this part of the xiphoid process; in addition, if the patient is thin or does backward bending movements, it is more likely to see this condition; 2. This situation may be caused by muscle spasm, such as the patient did excessive exercise for this area, may cause excessive fatigue of the rectus abdominis muscle here, when the patient rested, there may also be muscle spasm and lead to the throbbing; 3, this situation may be due to cardiovascular-related pathology, such as the patient in the development of cardiac hypertrophy, the development of a coarctation 3. This condition may be caused by cardiovascular-related pathologies, such as cardiac hypertrophy, aortic aneurysm or arterial stenosis, which may lead to excessive pulsation and cause the patient to see or feel the pulsation here; 4. The patient may mistake the peristaltic waveform for the subxiphoid process.
