What is Cavotricuspid Isthmus line?
The cavotricuspid isthmus (CTI) is a part of the right atrium located between the inferior vena cava (IVC) ostium and the tricuspid valve. The CTI is a relatively new concept that was first introduced by Cosio et al. (1993); this region of the heart plays an essential role in the atrial flutter circuit [1].
Is TSH 2.59 normal?
The normal range of TSH levels in adults is between 0.4 to 4.0 mIU/L (milli-international units per liter). Some research suggests that this range should actually be more like 0.45 to 2.5 mIU/L. The TSH range may also vary slightly based on the testing facility where your blood is being analyzed.
Is TSH 3.02 normal?
Normal Values: Normal values are from 0.4 to 4.0 mIU/L for those with no symptoms of an under- or over-active thyroid. If you are being treated for a thyroid disorder, your TSH should be between 0.5 and 2.0 mIU/L.
Is TSH 4.84 normal?
TSH levels typically fall between 0.4 and 4.0 milliunits per liter (mU/L), according to the American Thyroid Association. Ranges between laboratories will vary with the upper limit generally being between 4 to 5. If your level is higher than this, chances are you have an underactive thyroid.
What is atypical flutter?
The definition of atypical atrial flutter includes a broad spectrum of other macroreentrant tachycardias in which the wave front does not travel around the tricuspid annulus.
How serious is a flutter?
Although atrial flutter is usually not life-threatening at first, it does limit how well your heart pumps blood. This can cause a clot to form in your heart. If the clot breaks loose, it could lead to a stroke. Over time, atrial flutter can weaken your heart muscle.
Does vitamin D affect the thyroid?
in a small sample size of 30 subjects observed that vitamin D deficiency is associated with lower thyroid levels [25]. In our study, we found that the odds of developing hypothyroidism were significantly higher among patients with intermediate and deficient levels of vitamin D.
