Rapid heartbeat during urination may be a normal physiological manifestation, or it may be a manifestation of disease, this situation is not normal.
1. Under physiological conditions, if the bladder is overfilled, it will increase the intra-abdominal pressure to make the return blood volume decrease. When the bladder is emptied, the intra-abdominal pressure decreases, and the return blood volume decreases accordingly, thus prompting the sympathetic nerve excitement to elevate the heart rate to increase the return blood volume, which will lead to the performance of rapid heartbeat. Generally, this kind of rapid heartbeat has no obvious symptoms and is a normal reaction of the human body.
2. In some disease states can also appear when urinating fast heartbeat. Urological diseases such as urinary tract infections or kidney stones, urinary frequency, urinary urgency, urinary pain and other uncomfortable symptoms can cause sympathetic excitation, resulting in rapid heartbeat.
If the symptom persists even after eliminating physiological conditions, you need to consult a doctor in time for standardized diagnosis and treatment.
