Brief Answer:
Tachycardia without hypertension can be treated with bystolic medication

Detailed Answer:
Hi XXXX,
Thanks for writing in to us.

I have read through your query in detail.
Bystolic contains nebivolol which is a selective beta-adrenoblocker and blocks certain receptors to cause the blood vessels to relax. This will bring down the heart rate. As there is no hypertension, it will not have any effect on your blood pressure if it is in the normal range.

Medical research studies have shown that it can be given to control tachycardia in patients without hypertension.

Please take Bystolic as recommended by your doctor and do not stop taking it without asking your doctor.

Hope this answers your question. Please feel free to correct any oversight in my interpretation of your problems and discuss them in detail as per your requirements.

Hope your query is answered.
Do write back if you have any doubts.

Regards,
Dr.Vivek
