Different instruments have different display systems. However, in my opinion, this is what the instrument showed: Blood Pressure (BP) 203 / 112 mm of Hg and pulse 64/minute.
1. Your immediate concern should be to bring blood pressure under control. Therefore, see a primary physician as soon as possible. Measure the blood pressure again.
If it remains high or increases further, take your husband to the emergency room in hospital. Anyway, having a headache that he has never had before is also a reason you should take him to emergency.
2. EKG is electrocardiograph. It is recording of electrical impulses in heart and gives crucial information about condition of heart. Your husband was advised EKG in view of his
high BP. EKG will, along with detecting other problems in heart, will also show whether long term high BP has affected his heart.
3. Parkinson's disease is very slowly progressive disorder. Therefore, you can surely afford to wait for a couple of weeks to see the
neurologist.
4. Since you have already started
Amoxycillin, you should ensure that you give it in adequate dosage for adequate days. The dose is 250 to 500 mg three times a day for 7 to 10 days.
5. Give him alkezelter plus only as long as he has severe symptoms.
I hope this answers your questions.
