1 The disease can cause breathlessness and a dry cough. 2  Heliotrope rash can also result in inflammation of the cardiac muscles or myocarditis, and other cardiovascular conditions. 3  A small percentage of the patients may also experience cardiac arrhythmias and congestive failure of the heart.ome of the complications associated with heliotrope rash are discussed below: 1  Complications of muscle weakness: 2  When the esophagus experiences muscle weakness then patients may elicit dysphagia or swallowing difficulties. 3  This in turn can result in loss of weight and malnutrition.
When price elasticity of demand equals one, demand is unit elastic (the percent change in demand is equal to the percent change in price). Finally, if the value is greater than one, demand is perfectly elastic (demand is affected to a greater degree by changes in price).
(2) Perfectly Inelastic Demand: When the quantity demanded of a good dose not change at all to whatever change in price, the demand is said to be perfectly inelastic or the elasticity of demand is zero. For example, a 30% rise or fall in price leads to no change in the quantity demanded of a good.
