Please answer this: Extract the answer to the question from the following context. Question: What area of the earth did Ptolemy study according to the text? Context: The Greco-Egyptian scientist Claudius Ptolemy referred to the larger island as great Britain ( - megalis Brettanias) and to Ireland as little Britain ( - mikris Brettanias) in his work Almagest (147148 AD). In his later work, Geography (c. 150 AD), he gave these islands the names Alwion, Iwernia, and Mona (the Isle of Man), suggesting these may have been names of the individual islands not known to him at the time of writing Almagest. The name Albion appears to have fallen out of use sometime after the Roman conquest of Great Britain, after which Britain became the more commonplace name for the island called Great Britain.

Please answer this: Extract the answer to the question from the following context. Question: What other symptoms occur in the heart after damage is incurred? Context: Shortness of breath occurs when the damage to the heart limits the output of the left ventricle, causing left ventricular failure and consequent pulmonary edema. Other symptoms include diaphoresis (an excessive form of sweating), weakness, light-headedness, nausea, vomiting, and palpitations. These symptoms are likely induced by a massive surge of catecholamines from the sympathetic nervous system, which occurs in response to pain and the blood flow abnormalities that result from dysfunction of the heart muscle. Loss of consciousness (due to inadequate blood flow to the brain and cardiogenic shock) and sudden death (frequently due to the development of ventricular fibrillation) can occur in MIs.
