A fixed-rate pacemaker sends electrical prompts to your heart at an unchanging rate. Its drawbacks include that it is somewhat difficult to adapt to a state of physical exertion or emotional arousal.
A more advanced type, called a demand pacemaker (there are several types) kicks in after your cardiac function varies outside a pre-set normal rate. It then brings your heartbeat into a more efficient rhythm. (Sinus-rhythm.)
A demand pacemaker does not take the place of an implanted defibrillator! If a lifethreatening cardiac arrhythmia develops, it takes a defibrillator -- an implanted one or an external unit used by someone trained to respond -- to correct ventricular fibrillation. If it is not corrected, v-fib is fatal.
Demand pacemakes are used to restore a normal heart rate that only becomes abnormal occasionally. A fixed rate pacemaker is used when the problem is always there and the heart won't keep going without constant help.
difference between elastic and inelastic demand
distinguish between a term security and a demand security
Demand is to ask for something forcibly. Exchange is to trade.
Demand schedule is a tabular representation nd Demand curve is a graphical representation

a demand schedule is a table showing the relationship between the price of a good and the quantity demanded , but a demand curve is a graph showing the relationship between the price of a good and the quantity demanded.
Demand schedule: a list of demand/price equivalencies. It can best be seen as a table with discrete points. Demand function: a continuous function of price-demand interaction. Main difference: schedule is discrete; function is continuous.
a change in demand is a movement along the demand curve, and a change in quantity demanded is a shift in the demand curve
if demand falls due to change in price of commodity its terms in Economics as contraction in demand, and if demand falls due to other reasons its term decrease in demand...
Supply is the amount produced and demand is the amount that is wanted.
what are the difference between demand and grafter
peak is when the demand of electric power is very high, and off peak is when the demand is low
