I have been diagnosed with both tachycardia and bradycardia at the same time and was told that it was also known as Sick Sinus Syndrome or also Sinus Node Dysfunction. common symptoms are Heart palpitations, chest pain, fainting or dizziness, confusion or light-headedness , facial flushing, and fatiuge. this is what i have been told and currently i am being treated with medications to counteract each. hope this was somewhat helpful.
Well I have a natural genetic bradycardia rhythm and I also have a SVT which is a tachycardia condition. My heart rate can go from 44 beats per minute to 229 beats per minute in the matter of 1 heartbeat. I've never heard of tachy-brady syndrome but I think what I have is different.
I would say in answer to your question though - yes someone can have both.
I think if you had anything to really worry about they would have said something to you in response to your stress test. Usually good doctors will take a little time for you to ask questions when conferring with you about test results. You seem a little anxious about the results still though so I would sggest another appointment to talk it over with him/her.

I agree with bobad. In your particular case, I would bet that the tachy part was caused by the drugs that were administered. Those drugs are used for the sole purpose of raising your heart rate.
During the testing, they are administering drugs that raise the heart rate. That could account for the tachy.
It is possible (and not real uncommon) to have tachy and brady without diagnostic drugs. In fact, those who have tachy-brady syndrome can experience both tachy and brady within seconds.
