Hello,

Thank you for asking the query.

Yes Hypertension can cause or precipitate arrhythmia and can cause symptoms to fluctuate. So it is very important to control your blood pressure. Also certain blood pressure medication can precipitate hypertension and these should be avoided.

The symptoms you are experiencing now, need not be necessarily due to arrhythmia or hear rate irregularity. This could be due to anxiety or some sympathetic over activity. But it is prudent to get in touch with your Doctor and have it checked.  

Please feel free to ask followup question via this email itself.  Thank you.
