Researchers have found a strong link existing between thyroid function and atrial fibrillation (AF), an abnormal heart beat that increases risk of stroke and heart diseases.
Atrial Fibrillation - Causes, Symptoms, Diagnosis, Treatment, Complication, Risks
Atrial fibrillation may not be life-threatening in itself but it is important to understand the causes, symptoms and treatments because of the risk of life-threatening complications.

‘Patients with genetically-determined variations in thyroid hormones, despite having physiologically accepted ‘normal’ range are more susceptible to AF risk.’
Previous observational studies have found that subclinical hyperthyroidism, an overactive thyroid which does not meet the clinical threshold for diagnosis or treatment, nevertheless can increase the risk of AF. But whether to treat subclinical hypo- or hyperthyroidism to reduce AF risk remains a matter of debate in the medical community. The current study, published today in the journal JAMA Cardiology, found that genetically determined variations in thyroid function, even those which fall within a physiologically accepted "normal" range, still can increase the risk for AF.
The decision to treat subclinical thyroid disease should account for this new evidence, as "antithyroid medications to treat hyperthyroidism may reduce AF risk (while) thyroid hormone replacement for hypothyroidism (low thyroid function) may increase AF risk," the researchers concluded.

Cardiac Pacemaker for Abnormal Heart Rhythms – Types, Advantages & Risks
A pacemaker stimulates the heart with electrical signals when it detects arrhythmias of the heart. Pacemakers are classified based on the number of lead electrodes used and the type of pacing involved.

Hyperthyroidism (Overactive Thyroid) - Causes - Symptoms - Diagnosis - Treatment
Hyperthyroidism is a condition in which the thyroid gland makes excessive thyroid hormone. Grave’s disease is the most common cause of hyperthyroidism.
