Dear Jo,
YES the second 30 day event monitor is key to capturing the cause of your daughter's collapse-as it is unlikely for anyone to pass out just from sinus tachycardia. Because she has passed out (this often times is the only warning of a life threatening arrhythmia) some EP cardiologists might chose to just study her heart's electrical system with a low risk invasive procedure called an EP study.
Ask your daughter's EP doctor what he thinks of doing an EP study which he may say that he will consider in the future, perhaps if the second event monitor shows nothing that could be responsible for your daughters symptoms.
Tell your daughter that this type of problem requires patience on everyones part, in some patients it can be months or even a year until you catch tha abnormality, and just so you understand, just because you do an EP study, there is NO
guarantee that the doctor will be able to reproduce the bad rhythm. In the case where you can not figure out the cause but you suspect a rhythm disturbanc then the patient willoften be given a trial of drug therapy. It would be best if you and your daughter could discuss these issues as well as the longterm plan with her EP doctor.
