These 3 Conditions Can Actually Reverse AFib

Added: 2026-06-02

[00:00:00]These are situations where treating the underlying problem may eliminate AFib entirely.

[00:00:05]The first is hyperthyroidism.

[00:00:07]Especially in female patients, this is a lab that any provider has to check when first encountering a patient with AFib.

[00:00:16]When the thyroid gland is overactive, it can drive the heart into AFib. Once the thyroid is treated and hormone levels normalize, AFib often resolves completely.

[00:00:28]The second is acute lung problems, pneumonia, a pulmonary embolism, which is a blood clot to the lungs, or other sudden lung conditions can trigger AFib.

[00:00:39]Remember, the right side of the heart pumps against the lungs, so anything affecting, you know, the lungs, you know, by that relationship can affect the heart.

[00:00:49]Once the lungs heal, the AFib may not return.

[00:00:53]The third is what cardiologists call holiday heart syndrome.
