10 Possible Causes for Conduction Disorder of the Heart, patients possibly clinically asymptomatic, Variable Expressivity

Did you mean: Conduction Disorder of the Heart, patients, possibly clinically asymptomatic, Variable Expressivity

  • Brugada Syndrome

    Brugada syndrome (BrS) is a genetic heart disorder due to alteration of the ion channels function that causes an impaired in the cardiac conduction system.[] Seven relatives also carry the mutation and showed a Brugada syndrome with an incomplete and variable expression.[] CONCLUSION: Drug-induced BS has a good prognosis if asymptomatic; however, SCD is possible.[]

  • Cardiomyopathy

    It is recognized that arrhythmias and conduction disease may be primary myocardial disorders.[] The disorder is thought to be inherited in an autosomal dominant fashion with variable penetrance and variable expressivity.[] […] findings Very variable, many patients remain asymptomatic Exercise-induced ventricular arrhythmias palpitations , syncope , possibly sudden cardiac death Atypical chest pain[]

  • Arrhythmogenic Right Ventricular Dysplasia

    Implantable cardioverter-defibrillators in lamin A/C mutation carriers with cardiac conduction disorders.[] The disease is inherited as an autosomal dominant trait with incomplete penetrance and variable expressivity.[] The patient was asymptomatic and the clinical relevance of this finding would be raised in case a possible differential diagnosis of right heart overload should be necessary[]

  • Orthostatic Hypotension

    Abnormalities of the electrical conduction system including heart rates that are too slow or too fast may cause changes in blood pressure.[] We furthermore calculated within participant variability in SBP related to postural change, expressed as coefficient of variation.[] These findings suggest that clinically asymptomatic orthostatic hypotension in Parkinson's disease patients may acutely worsen neuropsychological performances with possible[]

  • Mitral Valve Prolapse

    The aim of the paper was to assess heart rhythm and heart conduction disorders in adolescents with primary mitral valve prolapse (MVP) and myxomatous valve degeneration of[] This may represent two stages in disease development, variable expression, or perhaps genetic heterogeneity.[] patients in experienced surgical centers. 2 Editorial p 768 Clinical Perspective p 804 Comprehensive echocardiographic evaluation of MR has made it possible to diagnose the[]

  • Adenomyosis Uteri

    Conduct conduct disorders. Congenital congenital anomalies. COPD chronic obstructive pulmonary disease. Drugs drug use disorders.[] Further, there is a great deal of variability in the expression of aromatase protein in the eutopic endometrium from women with the disease.[] Case presentation Clinical summary The patient was a 57-year-old nulliparous, asymptomatic woman of normal weight. She was in follow-up for a fibromatous uterus.[]

  • Athletic Heart Syndrome

    Importantly, cases of death occurring during physical activity are not caused by athletic heart syndrome, but by undiagnosed heart disorders.[] Intraobserver variability was tested from blinded measurements made on the same tracings, 6 months apart, by one observer (A.P.).[] Among the many alternative causes are episodes of isolated arrhythmias which degenerated into lethal VF and asystole, and various unnoticed, possibly asymptomatic cardiac[]

  • Familial Isolated Dilated Cardiomyopathy Type 2A

    Working Group on Inherited Cardiac Disorders, line 27/50, Interuniversity Cardiology Institute of The Netherlands.[] Hoffman JD, Jacobson Z, Young TL et al (2005) Familial variable expression of dilated cardiomyopathy in Alström syndrome: a report of four sibs.[] Flow diagram with steps in clinical assessment of patients with a possible genetic cause of DCM. Symptomatic family members.[]

  • Sensorineural Deafness with Dilated Cardiomyopathy

    Pointers in examination: Take a family history and suspect if: Family history of heart failure, sudden death, conduction disorders, atrial fibrillation, pacemakers, stroke[] Variable expressivity.[] A corollary of this question is the fact that the genetic factors underlying penetrance and variable expressivity in FDC are still unknown.[]

  • X-Linked Scapuloperoneal Myopathy

    […] transplant may be needed for end stage heart failure [8] • Physical therapy [1] • Cardiac pacemaker or implantable cardioverter defibrillator for AV block and conduction[] expression of the disease phenotype The molecular abnormality is an expansion of a CTG nucleic acid triplet repeat sequence on the nineteenth chromosome The muscle weakness[] Another patient (case 8) had two mutations, one inherited from the asymptomatic mother (Family 4).[]
