question: Have a hx of sinus tach n take Lopressor to control. Had flu 3 weeks ago, then secondary infection, still having aches n low grade fever yesterday. Took Tamiflu, then Levaquin and Prednisone for a week. Went back to dr. today n told it was bronchitis. Having inspiratory wheeze, bronchospasm, and resting HR of 131. Dr. Gave me Biaxin p.o., Rocephin IM, Decadron IM, Albuterol, and on 2nd round of Prednisone. I can feel left side of chest with the tachycardia. Could this secondary infection have affected my heart?
