777 Possible Causes for Hypothyroidism, Sinus Tachycardia

  • Adrenal Insufficiency

    Basal hormone levels and pituitary function tests indicated secondary hypothyroidism and adrenal insufficiency due to hypopituitarism.[] At admission, his blood pressure was 82/52 mmHg and he had sinus tachycardia of 130/min.[] Further endocrinological tests performed suggested central hypothyroidism and hypogonadism.[]

  • Hyperthyroidism

    Cases of conversion from hyperthyroidism to hypothyroidism have been reported but conversion from hypothyroidism to hyperthyroidism is very rare.[] ECG Examples Example 1 Sinus tachycardia Example 2 Related Topics Hypothyroidism Left ventricular hypertrophy References Slovis C, Jenkins R.[] The most common are sinus tachycardia, an abnormally fast heart rate that tops 100 beats per minute, and atrial fibrillation, a disorganized rhythm in the heart's upper chambers[]

  • Sinus Tachycardia

    For example fever, infection, hypothyroidism, anemia, or any other problem that increases the metabolic rate can result in sinus tachycardia.[] Sinus tachycardia ECG readout of an individual with sinus tachycardia. Here the heart rate is around 150.[] Inappropriate sinus tachycardia (IST) is a syndrome in which the sinus heart rate is inexplicably faster than expected and associated symptoms are present.[]

  • Addison's Disease

    A 57-year-old Caucasian woman with known autoimmune hypothyroidism diagnosed in 2006 presented to hospital with flu-like symptoms and circulatory collapse.[] An electrocardiogram showed sinus tachycardia, low voltage, negative T-waves in V5 and V6 and a corrected QT interval of 590 ms.[] On physiological steroid replacement therapy, her "hypothyroidism" resolved.[]

  • Depression

    Heart Attack Heart Disease Heartburn Hepatitis C Heroin Herpes High Blood Pressure High Cholesterol Hives Hoarding Hodgkins Lymphoma Huntingtons Disease Hyperthyroidism Hypothyroidism[] We experienced a man in his 20s with inappropriate sinus tachycardia (IST) initially diagnosed and treated as depression who was steadily treated with radiofrequency catheter[] When the hypothyroidism is treated it usually reduces the depression.[]

  • Cardiomyopathy

    ., hypothyroidism or hypertension). Patients are treated as any patient with heart failure; indeed, all patients with heart failure have some sort of cardiomyopathy.[] Sinus tachycardia not due to blood loss can be treated with IV propranolol. This improves LV filling.[] Chief among these are the cardiomyopathies caused by alcohol abuse, and underactive thyroid (hypothyroidism), and iron overload disease (hemochromatosis).[]

  • Heart Failure

    Chronic diseases — such as diabetes, HIV, hyperthyroidism, hypothyroidism, or a buildup of iron (hemochromatosis) or protein (amyloidosis) — also may contribute to heart failure[] Her ESR, Troponin I and Brain natriuretic peptide were elevated with normal CRP and electrocardiogram showed sinus tachycardia with wide spread ST depression.[] These diseases include: anemia hyperthyroidism hypothyroidism emphysema Certain behaviors can also increase your risk of developing heart failure, including: smoking eating[]

  • Theophylline

    A possible drug interaction, hypothyroidism and cardiac failure were ruled out.[] An electrocardiogram showed a sinus tachycardia. Arterial blood gas analysis revealed a mixed metabolic acidosis and respiratory alkalosis.[] Levothyroxine Thyroid dysfunction can modestly affect theophylline requirements; isolated cases of theophylline toxicity have been reported in patients being treated for hypothyroidism[]

  • Overdose

    The patient had a history of hypothyroidism, which was managed with thyroid hormone replacement (levothyroxine 100 μg per day).[] Four days after overdose, the patient's sinus tachycardia and prolonged QTc and QRS intervals resolved with symptomatic management, but she soon developed sinus bradycardia[] The patient presented with seizure, sinus tachycardia with prolonged QTc and QRS intervals, dilated pupils, and agitation.[]

  • Diphenhydramine

    A 36-year-old woman with a medical history of hypothyroidism on levothyroxine was brought to the emergency department with active seizures by emergency medical services after[] Initial electrocardiograms revealed sinus tachycardia at a rate of 180 beats per minute, a prolonged QRS of 130 milliseconds (from a baseline of 65 milliseconds), and a positive[]
