@cash298 You mean the Holter? They contact the cardiologist who ordered it. Example: It was 3 years ago. I sent mine back two Mondays before Thanksgiving. Had a syncope the day before (Wednesday) Thanksgiving. Friday morning, the day after Thanksgiving, cardiologist called my husband with the results. Do not know if the results came on late Wednesday or that morning. Hope that answers your question and I sincerely hope the results are known faster for you.
