Thanks for your question. Parvovirus infection should not normally cause sinus tachycardia, unless you have myocarditis. Have you had an ECG and/or an echocardiogram? Thyroiditis of course may certainly cause a tachycardia if the thyroid is overactive, but the tachycardia should disappear once thyroid function returns to normal.
Bisoprolol does not cause a cough. and I suspect the cough when you started bisoprolol is simply coincidence and was due to something different. .If you want to test the relationship between bisoprolol and coughing, then I would simply wean yourself off bisoprolol over a period of a few days, wait a week until the cough has completely gone, and then re-start bisoprolol. My guess is the cough will not reappear.
2.5 mg of bisoprolol would normally be an adequate daily dose for a young woman with sinus tachycardia and it should not normally be necessary to increase the dose to 5 mg per day, but please discuss this with your doctor.
With every good wish, JT
