Is atrial fibrillation a symptom of hyperthyroidism?

What is difference between thyrotoxicosis and hyperthyroidism?
Hyperthyroidism is characterised by increased thyroid hormone synthesis and secretion from the thyroid gland, whereas thyrotoxicosis refers to the clinical syndrome of excess circulating thyroid hormones, irrespective of the source.
What is factitious thyrotoxicosis?
Factitious thyrotoxicosis; Thyrotoxicosis factitia; Thyrotoxicosis medicamentosa; Factitious hyperthyroxinemia. Factitious hyperthyroidism is higher-than-normal thyroid hormone levels in the blood and symptoms that suggest hyperthyroidism. It occurs from taking too much thyroid hormone medicine.
Why does Graves disease cause atrial fibrillation?
In addition, thyroid hormone goes higher sensitivity to sympathetic nerve as it increases the number of myocardial beta receptor. Therefore, when the thyroid hormone is excessive value, tachycardia and atrial fibrillation may occur regardless of the cause.
Can Graves disease cause atrial fibrillation?
Therefore, when the thyroid hormone is excessive value, tachycardia and atrial fibrillation may occur regardless of the cause. The atrial fibrillation in Graves’ disease can expect spontaneous reversion to sinus rhythm when the hyperthyroidism is controlled.
What is another name for hyperthyroidism?
The term hyperthyroidism covers any disease which results in overabundance of thyroid hormone. Other names for hyperthyroidism, or specific diseases within the category, include Graves’ disease, diffuse toxic goiter, Basedow’s disease, Parry’s disease, and thyrotoxicosis.
What causes iatrogenic hyperthyroidism?
Iatrogenic thyrotoxicosis may be caused by (1) subacute thyroiditis (a result of lymphocytic infiltration, cellular injury, trauma, irradiation) with release of preformed hormones into circulation; (2) excessive ingestion of thyroid hormones (“thyrotoxicosis factitia”); (3) iodine-induced hyperthyroidism (radiologic …
Does hyperthyroidism cause heart palpitations?
Hyperthyroidism: Excess thyroid hormone Excess thyroid hormone also causes the heart to beat harder and faster and may trigger abnormal heart rhythms. One is atrial fibrillation, a disorganized rhythm in the heart’s upper chambers. A related symptom is palpitations, a sudden awareness of your heartbeat.

Which is a risk factor for subclinical hyperthyroidism?
The frequency of atrial fibrillation is high in patients with subclinical hyperthyroidism. A prospective cohort study in approximately 2,000 adults (age > 60 years), with a follow-up period of 10 years, showed that low serum TSH level is a risk factor for atrial fibrillation (39).
What are the ICD 9 and ICD 10 gems?
The ICD-9 and ICD-10 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
