The need for medication after pacemaker placement is related to the basic condition of the patient’s heart, as follows: 1. If the heart has no other problems and the electrical activity of the heart is abnormal, the pacemaker can solve the electrical activity problem and no medication can be taken; 2. If the patient suffers from other diseases such as coronary heart disease, hypertension or diabetes, the pacemaker can only solve the electrical activity of the heart, but other problems still exist and the patient needs to take the corresponding medication. Patients need to take appropriate medication. For example, patients with coronary artery disease need to take dual antiplatelet and anti-atherosclerotic drugs; patients with hypertension need to take antihypertensive drugs and patients with diabetes need to take hypoglycemic drugs. The specific medication should be combined with the clinical situation and guided by the doctor’s interview.
