Premature Atrial Contraction A premature atrial contraction (PAC) is a kind of irregular heartbeat (arrhythmia). It happens when the heart beats too early and then pauses before beating again. PACs are also called skipped heartbeats because they may make you feel like your heart is stopping for a second. CAUSES Your heart has four chambers. Normally electrical signals spread across your heart and make all the chambers beat together. During a PAC‚ the upper chambers of the heart (atria) beat too

Muscle Fiber contractions for our purposes begins with the arrival of action potential (action potential- is an electrical current) at the end of the axon terminal (axon terminal- the swollen distal end of the motor neuron axon). When the action potential reaches the axon terminal the action potential causes the voltage- gated calcium ion channels to open allowing calcium to flow in from extracellular fluid. The presence of calcium in the axon terminal causes synaptic vesicles (synaptic vesicles-

costs at the original budgeted activity level. True False 3. The overhead spending variance and the overhead efficiency variance are useful only if variable overhead really should be proportional to the activity measure that is being used in the flexible budget. True False 4. The variable overhead efficiency variance reflects how efficiently variable overhead resources were used. True False 5. A reason for keeping a constant denominator activity level is to maintain stability in the amount of

cost behavior is also identifying the key resources that are performed‚ resources used in performing these activities‚ costs of the resources‚ and what the cost is driven from. 2-2. Two rules of thumb when analyzing cost behavior are to manage what the company manufactures‚ sells‚ and to give advice as to where costs can be reduced. 2-3. Three examples of a variable cost are a 12% increase in the production of dresses‚ which will cause a 12% increase in variable costs. A 10% increase in clothes will
