Anyone had Tachycardia during or just after Herceptin?

[Kathy T]

Jessica, I had one episode,requiring an ED visit. Troponin levels were not checked. I was on a low dose beta blocker and would have occasional bouts of tachycardia which were controlled with an extra dose of the beta blocker. My dose is now higher and I've had no further problems. I've remained on Herceptin for 12 years as I am stage 4. My echos have been normal.
