In this short video, Dr. Tabatha Barber shares a personal anecdote about her thyroid treatment. She was taking 50 µg of levothyroxine with TSH levels around 4.5–4.7 and experienced heart palpitations. After adding a small dose of T3, the palpitations stopped, leading her to conclude that T3 is necessary for a healthy heartbeat and to prevent arrhythmia. She emphasizes the breakthrough nature of this observation.

It doesn't even make any sense. I think I was on 50 micrograms at the time and my labs were showing a TSH 4.5, 4.7. And when I added in that T3, the heart palpitations actually went away. And I was like, okay, I'm onto something. This is crazy. And then the more I talked to you and continued to study, I was like, wow, like we actually need T3 to have a healthy beating heart. For it to not go into arrhythmia.
