After you've successfully hooked up the holter monitor on your Boxer, they've left it on for the full 24 hours, and you've sent the tape/recording in to be analyzed, you get to play the waiting game. Some services are very fast, consistently offering 24-hour turn-around times once they receive your recording. Others takes days or even weeks. If you're not good with waiting, or if you need the results sooner rather than later, you might want to check out customer satisfaction and turn-around times before you rent or purchase your holter.
