If the blood pressure is high and there is intracranial hemorrhage, it will lead to coma, aphasia and hemiplegia. If the blood pressure is high and there is heart failure, dyspnea may occur, which is labor dyspnea in the early stage, and then paroxysmal dyspnea at night, sitting breathing, acute pulmonary edema, and cough pink foamy sputum may occur. If the blood pressure is high and there is arrhythmia, it can be manifested as palpitation. The common symptoms of hypotension mainly include dizziness, especially when the posture changes, and even postural syncope.
