If the patient has a fast heartbeat and high blood pressure, it is recommended that he or she first take a beta-blocker, which is a first-line antihypertensive drug that has a relatively weak antihypertensive effect but can significantly slow down the heart rate. After taking this drug, it is recommended that the patient can combine it with a more potent antihypertensive drug, such as perindopril indapamide tablets. If the blood pressure still cannot be reduced to a safe range by taking these drugs alone, calcium channel blockers can also be used in combination, and the representative drugs are felodipine, nifedipine controlled-release tablets, and nifedipine extended-release tablets, all of which are very effective in lowering blood pressure. In addition, before using antihypertensive drugs must find out whether the patient currently has weakness in one limb or salivation at the corners of the mouth, first to rule out the occurrence of acute cerebrovascular disease, if necessary, head CT and diffusion-weighted imaging examination, and then oral antihypertensive drugs.
