Brief Answer:
Quick drop in blood pressure due to Felodipine....

Detailed Answer:

First, try to calm down as nothing bad is happening to you.

As I go through your blood pressure reading, I notice that your heart rate is 97 which is perfectly normal. Your blood pressure is also perfectly normal.

Felodipine appartains to the group of drug called calcium-blockers. They cause dilatation of peripheral blood vessels, thus, reducing peripheral resistence. In this way, your heart will find it easier to pump blood preventing spikes in blood pressure.

One of the side effects of such drugs is quick drops in blood pressure. This is what you have experienced: quick drop in blood pressure. Your heart is responding with fast heart beats.

Another reason to experience fast heart beats is stress/anxiety you got from what is happening to you right now.

Try to calm down, nothing worrisome. If you have atenolol or metoprolol (beta-blocker) you can take a dosage now. Take a good chamomile or valerian tea or pill to calm you down.

Monitor your blood pressure. If it will be this low in the afternoon, do not take the other medication for today. You should report this episode to your doctor/cardiologist as you need to adjust dosage of Felodipine or perhaps you need to change therapy.

All the best!
