I had symptoms for about a month or 6 weeks, and made an appointment with a cardiologist. He checked me quite thoroughly, wanted me to wear a halter monitor for 24 hours, come back and have a thyroid test run. I had no intention of wearing that ugly thing, so I went to another cardiologist who took about 7 months doing cardiac tests before deciding to send me to an endo–who diagnosed me that day! So, I would have been diagnosed on the first visit if I hadn’t been so vain, and/or if I had spoken up and said I didn’t want to wear the monitor. I was working and didn’t want to cancel a whole day of clients.
