43 Possible Causes for Huge QRS Complexes, Muscle Biopsy showing Presence of Vacuoles

  • Glycogen Storage Disease Type 2

    Muscle biopsy in Pompe disease shows the presence of vacuoles that stain positively for glycogen.[dx.doi.org] Quantitatively, muscle glycogen content is elevated up to tenfold above normal in infantile Pompe disease and to a lesser extent in late onset patients.[dx.doi.org] Furthermore, there is anesthesia risk (see section below) in infantile Pompe disease if an open biopsy is done. 26 This risk should be carefully considered, particularly if[dx.doi.org]

  • Cardiodysrhythmic Potassium-Sensitive Periodic Paralysis

    In periodic paralysis muscle biopsy may show a wide range of abnormalities, vacuoles being more specifically linked to the disease.[ajns.paans.org] The patient’s electrophysiological examination included nerve conduction study and electromyography (EMG) exclude the presence of myotonia and muscle biopsy showed mild myopathic[ajns.paans.org] Frequency or severity of attacks did not correlate with the presence of vacuoles but those were more easily found in patients with long term disease [10].[ajns.paans.org]
