Cardiology Questions Answered by Verified Cardiologists.
Hello from JustAnswer.
1. Yes, they would typically contact you if a serious arrhythmia occurred. However, a short run of A fib will usually not be considered something that is serious. If there was anything that would be an issue while on vacation, they would not have told you that it was fine to go.
2. Cold and cough medicines that contain decongestants can stimulate the heart and precipitate SVT or A fib in someone that already has a tendency to have such rhythms. However, these drug would not have done anything bad to the heart other than the stimulation that would have occurred only while the drug was in the system.
3. If there are no risk factors for developing A fib, it would be very unlikely that this loop would have shown any A fib.
4. So, the chances of developing A fib now is also quite low, and there is no reason why you should not enjoy your trip.
If I can provide any clarification, please let me know.
The risk factors for A fib are any anatomic heart condition that increases atrial size or pressure, which you obviously do not have with a normal echo, along with high blood pressure, alcohol use, thyroid disease, sleep apnea, diabetes, chronic lung disease, and age. A fib can occur with normal heart structures, but it is vastly less common in someone with normal atrial size and pressure.
SVT is usually only an irritation and not something serious.
It is very likely that the palpitations are benign. This sounds much more like SVT.
You are very welcome.
The cold medicine would not cause A fib, by itself. Typically, it will only exacerbate it if it is otherwise a problem.
