Context: I had a brief , mild arrhythmia this morning , probably lasted about ten minutes . I went to enter it in my phone and realized that the previous entry was last December . Have I really not had any arrhythmias in over half a year ? That 's pretty awesome . I guess those ridiculously expensive meds really work .

Answer:

What may be the reason for going so long without an arrythmia ?
