852 Possible Causes for Abnormal ECG, No Muscle Weakness, Pediatric Disorder

  • Duchenne Muscular Dystrophy

    Occasionally, however, females who carry a DMD gene mutation may have muscle weakness and cramping.[ghr.nlm.nih.gov] BACKGROUND AND PURPOSE: Duchenne muscular dystrophy (DMD) is a lethal progressive pediatric muscle disorder and genetically inherited as an X-linked disease that caused by[ncbi.nlm.nih.gov] The PR interval gradually increased with age, but no ECGs showed an abnormally prolonged PR interval.[ncbi.nlm.nih.gov]

  • Becker Muscular Dystrophy

    Little is known about parental motivations and expectations for clinical trials for rare pediatric disorders.[ncbi.nlm.nih.gov] Later symptoms Muscle weakness: Affects the proximal muscles of the limbs mainly.[patient.info] One of them has an abnormal ECG that showed right ventricular hypertrophy and sinus tachycardia and the others have abnormal echocardiograms (ejection fraction ranging from[doi.org]

  • Paramyotonia Congenita

    Kang, The Spectrum of Myotonic and Myopathic Disorders in a Pediatric Electromyography Laboratory Over 12 Years, Pediatric Neurology, 47, 2, (97), (2012).[doi.org] The resulting increase in ion flow interferes with normal muscle contraction and relaxation, leading to episodes of muscle stiffness and weakness.[ghr.nlm.nih.gov] ECG.[emedicine.medscape.com]

  • Hyperkalemic Periodic Paralysis

    But repeated attacks may lead to permanent muscle weakness. HyperPP responds well to treatment. Treatment may prevent, and may even reverse, progressive muscle weakness.[nlm.nih.gov] Tests that may be done include: ECG , which may be abnormal during attacks EMG , which is usually normal between attacks and abnormal during attacks Muscle biopsy , which[coordinatedhealth.com] Pediatric Critical Care. 5th ed.

Head lag and truncal hypotonia were noted at 4 months of age.[doi.org]
