183 Possible Causes for Electromyogram Abnormal, No Muscle Weakness, Respiratory Failure

  • Duchenne Muscular Dystrophy

    Mortality is typically related to combined respiratory failure and dilated cardiomyopathy.[] Muscle weakness Other names Myasthenia Specialty Neurology Muscle weakness is a lack of muscle strength.[] failure in the 2nd or 3rd decade.[]

  • Polymyositis

    In this case report, we describe the occurrence of diaphragmatic weakness and respiratory failure due to polymyositis with relatively well preserved power in limb muscles.[] An electromyogram showed abnormal nerve conduction with evidence of active denervation of most of the muscles tested.[] Some cases of polymyositis have manifestations of muscle weakness in the orbital muscles. Rare cases also have weaknesses in facial and bulbar muscles.[]

  • Myasthenia Gravis

    Respiratory failure due to disorders of the chest wall and respiratory muscles. In: MacDonnell KF, Fahey PJ, Segal MS Respiratory Intensive Care.[] Electromyogram (EMG). A test that measures the electrical activity of a muscle.[] Proximal muscle weakness is more often seen than distal muscle weakness.[]

  • Dermatomyositis

    ECMO was giving when the patient suffered acute respiratory failure.[] (EMG) which can demonstrate abnormal electrical activity in muscles and help distinguish weakness due to muscle disease from weakness due to nerve problems A nerve conduction[] Symptoms may include: Muscle weakness, stiffness, or soreness Problems swallowing Purple color to the upper eyelids Purple-red skin rash Shortness of breath The muscle weakness[]

  • Lambert Eaton Myasthenic Syndrome

    It is distinguishable from normal muscle cramps by the finding of prolonged bursts of high frequency repetitive muscle action potentials on the electromyogram (EMG).[] Results: in myasthenia gravis, initial weakness involved extraocular muscles in 59%, bulbar muscles in 29%, and limb muscles in 12% of the patients.[] As shown by these cases, the severe respiratory failure in LEMS is reversible with treatment.[]

  • Amyotrophic Lateral Sclerosis

    weakness.[] At some stage of the disease, patients may complain of breathlessness due to respiratory failure, thus needing a noninvasive mechanical ventilation (NIMV) support.[] Respiratory muscle weakness and failure is a common complication late in the course of disease.[]

  • Spinal Muscular Atrophy Type 1

    An EMG can detect abnormal electrical muscle activity due to diseases and neuromuscular conditions.[] AIM: This study described end-of-life care for children affected by spinal muscular atrophy type 1 (SMA1), which is characterised by progressive muscle weakness and develops[] The majority (76%) opposed invasive ventilatory support for chronic respiratory failure in SMA1.[]

  • Progressive Muscular Atrophy

    Two patients with axial-onset disease progressed rapidly to respiratory failure.[] She developed muscle weakness of the distal part of the left lower extremity at age 42, followed by muscle weakness and atrophy of the right lower extremity and upper extremities[] Numerous nemaline bodies were demonstrated in the pectoralis major muscle of an autopsy case of a 52-year-old woman, who died of respiratory failure after having suffered[]

  • Muscular Dystrophy

    failure.[] It causes progressive weakness in muscles of the face, arms, legs, and around the shoulders and chest.[] Of the entire study population, 50.5% had cardiomyopathy and 35.9% had respiratory failure.[]

  • Motor Neuron Disease

    Exploring the factors correlated with respiratory failure can contribute to disease management.[] […] wasting and weakness, absent reflexes, loss of weight and muscle twitching.[] The case report outlined below describes acute respiratory failure requiring non invasive ventilation (NIV), at the time of diagnosis of MND.[]
