Is thyroid function intrinsically linked to insulin sensitivity and endothelium-dependent vasodilation in healthy euthyroid subjects?
Thyroid function tests are intrinsically linked to variables of insulin resistance and endothelial function. It is possible that underlying factors lead simultaneously to increased serum TSH, insulin resistance, ensuing dyslipidemia, and altered endothelial function even within current normal TSH levels.
Despite of introduction of new generations of ICDs, the problem of inappropriate ICD discharge could not be eliminated. The major problem is distinction between supraventricular arrhythmia and ventricular tachyarrhythmia.
