71 Possible Causes for Bradycardia, Hypothyroidism, Incomplete Right Bundle Branch Block

  • Cardiomyopathy

    ., hypothyroidism or hypertension). Patients are treated as any patient with heart failure; indeed, all patients with heart failure have some sort of cardiomyopathy.[] Sudden cardiac death Clinical risk assessment Models for estimating sudden cardiac death Prevention of sudden cardiac death Risk of sudden death in children Symptomatic bradycardia[] Chief among these are the cardiomyopathies caused by alcohol abuse, and underactive thyroid (hypothyroidism), and iron overload disease (hemochromatosis).[]

  • Conduction Disorder of the Heart

    […] factors that can cause or contribute to a rhythm disturbance include electrolyte abnormalities (particularly low potassium or magnesium), hypoxia, hormonal imbalances (eg, hypothyroidism[] Sinus Bradycardia Sinus bradycardia is a sinus rhythm with a rate of 40-60 bpm Atrial fibrillation/flutter Irritable sites in the atria fire very rapidly, between 400-600[] right bundle branch block.[]

  • Sinus Bradycardia

    Causes: congenital hypothyroidism hypothermia post myocardial infarct raised intra-cranial pressure drugs eg beta-blockers, digitalis, hypotensives rapid rise in blood pressure[] Bradycardia is not necessarily problematic.[] right bundle branch block (BBB), early repolarization, and isolated voltage criteria for left ventricular hypertrophy (LVH). 2.[]

  • Bradyarrhythmia

    Degenerative cardiac lesions caused by malabsorption and undiagnosed hypothyroidism in elderly women may contribute to the group of apparently isolated bradyarrhythmias.[] Management of bradycardia. The management of bradycardia depends upon the patient’s degree of symptoms.[] branch block 左脚ブロック left bundle branch block 完全左脚ブロック complete left bundle branch block 不完全左脚ブロック incomplete left bundle branch block 右脚ブロック right bundle branch block 完全右脚[]

  • Athletic Heart Syndrome

    Unexplained weight gain might be a red flag for a condition like sleep apnea or hypothyroidism.[] As mentioned previously, sinus bradycardia, AV blocks, extrasystoles, and early repolarization are hallmarks of athletic heart syndrome.[] Ventricular Hypertrophy criteria Wide QRS Complex (incomplete Right Bundle Branch Block ) Athletes: 14% Incidence Gene ral athletes: 10% Incidence Repolarization changes[]

  • Sick Sinus Syndrome

    […] diseases such as sarcoidosis, amyloidosis, scleroderma, and hemochromatosis Electrolyte problems such as high potassium levels Rare diseases that run in the family Trauma Hypothyroidism[] Abstract Bradycardia-dependent block or activation delay of the atrial tissue has not been documented in the literature.[] ECG examinations performed between 13 and 20 years old showed incomplete right bundle branch block and ST elevation with early depolarization.[]

  • Right Bundle Branch Block

    […] bradycardia Acute myocardial infarction Drugs—for example, β blockers, digoxin, amiodarone Obstructive jaundice Raised intracranial pressure Sick sinus syndrome Hypothermia Hypothyroidism[] However, it seems that these findings do not show true bradycardia-dependent RBBB.[] right bundle branch block (IRBBB).[]

  • AV Block Mobitz I

    Hypothyroidism in the elderly. Am J Med Sci. 1990;299:334–45. View Article PubMed Google Scholar Roberts CG, Ladenson PW. Hypothyroidism. Lancet. 2004;363:793–803.[] (C) Bradycardia with normal heart rate intervals at a rate of 55 after Mobitz type II AV block. (D) Mobitz type II AV block reappeared when the ureterus was repaired.[] : Incomplete right bundle branch block (IRBBB) Complete right bundle branch block (CRBBB) Left anterior hemiblock (incomplete) (LAHB) Left posterior hemiblock (incomplete)[]

  • Congenital Heart Block

    Nine women had hypothyroidism and 78 had normal thyroid function.[] Abstract Persistent fetal bradycardia in early pregnancy is a rare finding and indicates towards congenital heart block.[] incomplete right bundle branch block.[]

  • Dilated Cardiomyopathy

    We report a case of DCM associated with severe hypothyroidism with marked improvement on restoration of euthyroid state.[] The primary endpoint was 20% reduction in heart rate from baseline without inducing bradycardia or symptoms.[] The pacemaker also will help people with heart block (a problem with the heart's electrical system) or some bradycardias (slow heart rates).[]
