Reversible electrophysiological abnormalities in hypokalemic periodic paralysis.

Accidental intravenous bolus infusion of potassium chloride in a young man with hypokalemic periodic paralysis

Hypokalemic periodic paralysis is anautosomal dominantdisease characterized by muscle weakness or paralysis with a matching fall in blood potassium levels. Paralysis attacks often occur in adolescence and are induced by strenuous exercise followed by rest, high carbohydrateor high sodiummeal content, sudden changes in temperature, and even excitement, noise, flashing lights and cold temperature...

BILATERAL SUDDEN SENSORINEURAL HEARING LOSS (SSHL) WITH HYPOKALEMIC PERIODIC PARALYSIS (HPP)

Hypokalemic periodic paralysis - an owner's manual

This article focuses on questions that arise about diagnosis and treatment for people with hypokalemic periodic paralysis. We will focus on the familial form of hypokalemic periodic paralysis that is due to mutations in one of various genes for ion channels. We will only briefly mention other �secondary� forms such as those due to hormone abnormalities or due to kidney disorders that result in ...

Neonatal diaphragmatic paralysis caused by chest drains.

A boy delivered at 32 weeks' gestation developed bilateral pneumothoraces that required multiple chest drains. He was dependent on the ventilator for 52 days because of bilateral diaphragmatic paralysis. Electrophysiological studies confirmed phrenic nerve damage. He eventually made a full recovery. It is likely that this damage was caused by the insertion of the chest drains.

Unusual manifestations of arrhythmogenic right ventricular dysplasia as ventricular fibrillation, atrial paralysis, and hypoexcitable right ventricle.

Ventricular fibrillation occurred in an apparently healthy 19 year old man. The results of non-invasive and invasive studies suggested right ventricular dysplasia. Electrophysiological studies showed atrial paralysis, hypoexcitability of multiple areas of the right ventricle, and inducible poorly tolerated ventricular tachycardia.
