What should I do if I have sinus bradycardia?

Patient: Hello doctor: I had a 24-hour ambulatory ECG and the findings are as follows: 24-hour ambulatory ECG monitoring of sinus rhythm with a mean heart rate of 49 bpm, a minimum heart rate of 30 bpm occurring at 03:28 and a maximum heart rate of 100 bpm occurring at 09:59. 1000 R-Rs greater than 1.5 seconds, 2 segments of sinus-atrial wandering rhythm seen at night; 1 segment of P-R interval progressively prolonged up to 0.28 seconds; there were 15 supraventricular premature beats with no ST-segment excursion. T-wave hypoplasia can be seen. Diagnosis: 1. sinus bradycardia, occasional sinus-atrial wandering rhythm, 2. occasional premature atrial oscillations, 3. atrioventricular conduction delay, and 4. reduced sinus node function. Please give me some diagnostic advice, thank you! The local doctor gave me a month’s supply of 3 kinds of medications and said I should go back after taking them. I don’t know if they are the right medications: 1) Mono Fosinopril Sodium Tablets 2) Ginaldo Ginkgo Biloba Extract Tablets 3) Lipitor Atorvastatin Calcium Tablets The lab tests, ultrasound and fluoroscopy are all fine, the blood biochemistry is fine except for high cholesterol, and the blood pressure is 90/138. I have just taken the medication for a few days, and currently I have a soreness in my left back, and occasionally I seem to feel dizzy. I have just taken the medication for a few days. See if the right medicine has been prescribed or give me treatment advice. Cardiovascular disease specialist Wang Yunfei, Guangdong Provincial Hospital of Traditional Chinese Medicine
The first thing I want to do is to get a good idea of what I’m doing. 1, 24-hour ambulatory ECG results show vagal hyperfunction, if you like sports, it may be “athletes heart”, functional, if no symptoms, can not be treated. However, if you still have “sinus bradycardia” after the age of 40, further examination and treatment should be done. 2, Lipitor Atorvastatin calcium tablets, lipid regulating drugs, 10-20mg per night, 6 weeks after the review, blood biochemical cholesterol normal, can be reduced by half every night for six months. 3.Monol Fosinopril Sodium Tablets, is an antihypertensive drug, blood pressure is too low will cause dizziness, if you stop monitoring blood pressure once a day in the morning, in the evening, for a week, in the normal range, completely can not take antihypertensive drugs.
