845 Possible Causes for Hypothyroidism, Sick Sinus Syndrome

  • Cardiomyopathy

    Sick sinus syndrome is phenotypically similar to progressive cardiac conduction defect.[] ., hypothyroidism or hypertension). Patients are treated as any patient with heart failure; indeed, all patients with heart failure have some sort of cardiomyopathy.[] Chief among these are the cardiomyopathies caused by alcohol abuse, and underactive thyroid (hypothyroidism), and iron overload disease (hemochromatosis).[]

  • Coronary Artery Disease

    We included subjects with normal thyroid function (0.4-4.0 mIU/L, and normal free thyroxine, FT4, or 0.8 to 1.9 ng/dL), subclinical hypothyroidism (SCHypo; TSH 4.0 mIU/L and[]

  • Bradycardia

    Sick sinus syndrome includes a variety of disorders and pathologic processes that are grouped within one loosely defined clinical syndrome.[] […] with trisomy 21 including associated congenital heart disease, atlantoaxial instability, tracheal and subglottic stenosis, a predisposition to respiratory complications, hypothyroidism[] Hypothyroidism. Hypothermia.[]

  • Sinus Bradycardia

    […] a number of sick sinus syndrome risk factors.[] Causes: congenital hypothyroidism hypothermia post myocardial infarct raised intra-cranial pressure drugs eg beta-blockers, digitalis, hypotensives rapid rise in blood pressure[] Patients with a history of bradycardia, hypothyroidism, or concomitant beta-blocker use were excluded. Mean age of study patients was 44 8 years.[]

  • Bradyarrhythmia

    Sick sinus syndrome occurred significantly more frequently in women (28%) than in men (26%).[] Hypothyroidism 5. Advanced liver disease 6. Hypothermia 7. Typhoid fever 8. Brucelosis 9. Hypoxia, hypercapnia, acedemia 10. Acute hypertension 11. Vasovagal syncope 12.[] Continuous positive airway pressure therapy prevented atrioventricular blocks that emerged after cardiac pacing for sick sinus syndrome.[]

  • Sinus Tachycardia

    Bradycardia-tachycardia syndrome; Sinus node dysfunction; Slow heart rate - sick sinus; Tachy-brady syndrome; Sinus pause - sick sinus; Sinus arrest - sick sinus Olgin JE,[] For example fever, infection, hypothyroidism, anemia, or any other problem that increases the metabolic rate can result in sinus tachycardia.[] She has pretty much narrowed down the cause to either Sick Sinus Syndrome or Inappropriate Sinus Tachycardia.[]

  • Sick Sinus Syndrome

    Sick sinus syndrome (sinus node dysfunction) is defined as a group of arrhythmias associated with sinus node dysfunction.[] […] diseases such as sarcoidosis, amyloidosis, scleroderma, and hemochromatosis Electrolyte problems such as high potassium levels Rare diseases that run in the family Trauma Hypothyroidism[] Hypothyroidism . Electrolyte abnormalitites — e.g. hyperkalaemia . ECG in Sinus Node Dysfunction ECG abnormalities can be variable and intermittent.[]

  • Familial Sick Sinus Syndrome

    Abstract A family with sick sinus syndrome is presented: a mother and her 2 daughters affected with sinus node dysfunction.[] Other factors include negatively chronotropic drugs (drugs thats slow the heart rate), hypothyroidism and hypokalaemia.[] KEYWORDS: Nav1.5 voltage-gated sodium channel; mutation; sex; sick sinus syndrome[]

  • Thyroid Gland Disorder

    Another possibility is sick sinus syndrome (sinoatrial node disease) if it persists after normalizing thyroid level.[] Women, especially those older than age 60, are more likely to have hypothyroidism. Hypothyroidism upsets the normal balance of chemical reactions in your body.[] Very severe hypothyroidism is called myxedema.[]

  • Hypotension

    sinus syndrome, either long-acting, dihydropyridine or nondihydropyridine-type CCBs may be used.[] It may be associated with the following: Pregnancy Hormonal problems such as an underactive thyroid ( hypothyroidism ), diabetes , or low blood sugar ( hypoglycemia ) Some[] Nervous System disease (CNS) 1) Neuropathic DM, auto-immune disease Vitamin B 12 deficiency Syphilis amyloid cancer Renal failure Heavy metal toxicity alcoholism porphyria hypothyroid[]
