125. “Increased preload increases the force of contraction” is known as:
126. In a normal heart increased preload and increased contractility leads to:
127. in a diseased heart increased preload,increased contractility, and high blood pressure lead to
128. How can cardiovascular fitness can be improved at any age?
129. *The replacement of a severely damaged heart with a normal heart is called:
130. Which patients are candidates for cardiac transplantation?
131. *The heart begins its development from a group of mesodermal cells called:
132. When does the primitive heart begin to contract?
133. Why is the heart one of the first systems to develop?
134. A 40 ml polylurethane ballon mounted on a catheter is inserted into an artery in the groin and pushed forward to the thoracic aorta. The balloon is rapidly inflated and deflated to push blood into the coronary artery and sucking blood out of the left ventricle
135. A mechanical pump that helps a weakended ventricle to pump blood throughout the body so that the heart does not have to work as hard.
136. A large piece of the patient’s own skeletal muscle is partially freed up and wrapped arouned the heart. An implanted pacemaker stimulates the muscle to contract.
*137. *On the 28th day after fertilization the tubualar heart of the embryo is partioned into:
138. An opening between the right and left atria called the ______allows most blood to passes directly into the left atria in the embryo.
139. *Which factor plays a key role in the development of atherosclerotic plaques?
140. The number one risk factor in all CAD diseases is:
141. Which lipoprotein helps to reduce cholesterol in the blood?
142 *Which of the therapys for CAD are the least intrusive?
143. *What do Coarctation of the aorta, Patent ductus arteriosus, Septal defect, and Tetraology of Fallot have in commmon?
144. What conditions cause cyanosis, known as blue-baby syndrome?
145. A rapid but regular heart rate (160- 200 b/m) that originates in the atria is
146. An arrhythmia that occurs when the electrical pathways between the atria and ventricles are blocked, slowing the transmission of nerve impulses resulting in slow rate and “dropped” beats.
147. A rapid regular atrial contractions (240-360 b/m) accompanied by an atrioventricular block.
148. A common arrhythmia in older adults in which contration of the atria is asynchronous so that atrial pumping ceases, resulting in blood clots that causes strokes in brain.
149. An arrhythmia that originates in the ventricles and causes the ventricles to beat too fast (120 b/m) that is always associated with a recent myocardial infarction.
150. The most deadly arrhytmia where the ventricles quiver rapidly rather than contract. Ventricle pumping stops and circulatory failure and death occur without medical intervention. CPR and electrical shock from a defibrillator can often stop this arrhythmia.
