The symptoms of vertigo are caused by a sudden sensation of vertigo while sitting, which may involve more systems, and cerebral insufficiency of blood supply, which may occur transiently in elderly people. Otogenic vertigo, such as vertigo when changing position, or not being able to turn around or turn your head in one direction, will be more severe when you turn, accompanied by nausea and vomiting, but the possibility of otogenic vertigo is lower if you sit all the time and have symptoms. Blood pressure, if blood pressure is low or high, it will cause corresponding dizziness, head swelling and discomfort. Then there is the heart rate. If the vertigo is caused by cardiology, we should also consider bradycardia causing cerebral blood supply deficiency. Because the heart rate is very slow or brief cardiac arrest for a longer period of time, more than three seconds, there will be insufficient blood supply to the brain, and the symptoms of vertigo will appear. If a young person suddenly has a bout of vertigo, it may not be a big risk, but if an elderly person has vertigo, or if it is often accompanied by blackness in front of the eyes, he or she should pay attention to it and go to the cardiology and neurology departments of the hospital for corresponding examinations to clarify whether there is a slow arrhythmia, whether there is high blood pressure or low blood pressure, or whether there is a clinical diagnosis of insufficient blood supply to the brain.
