Slow heart rate and high blood pressure can exist in the same human body, generally like the slow heart rate of patients to clarify the cause of the disease, whether there is a serious sinus bradycardia, atrioventricular conduction block and other conditions. Hypertensive people in the application of antihypertensive drugs should also pay attention to avoid the application of drugs that cause slow heart rate, such as β-blockers try not to apply, hypertensive patients can choose the appropriate calcium channel antagonist, generally to nifedipine, amlodipine, such as drugs, to a certain extent, can be reflexively caused by the increase in heart rate, but the effect is not particularly obvious. Diltiazem also belongs to the calcium channel antagonist, but will cause heart rate slowing, patients should be careful not to apply. Usually, patients with hypertension combined with slow heart rate can wear 24-hour dynamic blood pressure and 24-hour dynamic electrocardiogram at the same time, in order to clarify the range of fluctuation of blood pressure, as well as whether there is a serious cardiac arrhythmia.
