Hi,
Although I have normal thyroid function, since my thyroid gland enlarged, my heart rate has been really low. Dropping as low as 45 bpm at rest, never raises above 65 bpm, at rest. It rarely goes over 70 bpm, after slight exertion, and I am always exhausted.
Around April this year, it was completely the opposite, my heart rate would never decrease at rest always 90-100 bpm.
I am a 45 year old male, always healthy till thyroid enlarging.
I see a cardiologist today, but he always tells me, he's a heart doctor and doesn't know anything about thyroid, etc....
Can a thyroid effect heart function, heart rate etc....
Any feedback would be appreciated.
