(Source: Thinkstock Images)Individuals with higher levels of thyroid hormone in the blood are more likely to develop irregular heartbeat, suggesting that the levels could help identify individuals at risk for the condition, researchers say. The findings showed that individuals with higher blood levels of thyroid hormone free thyroxine or FT4 — had 45 per cent increased risk of suffering from irregular heartbeat, compared to people with the lowest levels. Even more modest increases in thyroid hormone were associated with an increased risk, the researchers noted in the journal Circulation.
