Problem: Text: Inverted T wave is considered abnormal if inversion is deeper than 1.0 mm. Inverted T waves found in other leads other than the V1 to V4 leads is associated with increased cardiac deaths. Inverted T waves associated with cardiac signs and symptoms (chest pain and cardiac murmur) are highly suggestive of myocardial ischaemia. Other ECG changes associated with myocardial ischaemia are: ST segment depression with an upright T wave; ST segment depression with biphasic T wave or inverted T wave with negative QRS complex; T wave symmetrically inverted with a pointed apex, while the ST segment is either bowed upwards or horizontally depressed, or not deviated; and ST segment depression progressing to abnormal T wave during ischaemia free intervals. However, ST segment depression is not suggestive of ischaemic location of the heart. ST segment depression in eight or more leads, associated with ST segment elevation in aVR and V1 are associated with left main coronary artery disease or three-vessel disease (blockage of all three major branches of coronary arteries). ST segment depression most prominent from V1 to V3 is suggestive of posterior infarction. Furthermore, tall or wide QRS complex with an upright T wave is further suggestive of the posterior infarction.

Question: is t wave inversion in lead 3 normal?
A: no

Problem: Text: The method of breaking the fourth wall in literature is typically referred to as metafiction. Metafiction genre occurs when a character within a literary work acknowledges the reality that they are in fact a fictitious being. The use of the fourth wall in literature can be traced back as far as The Canterbury Tales and Don Quixote. However, it was popularized in the early 20 century during the Post-Modern literary movement. Artists like Virginia Woolf in To the Lighthouse and Kurt Vonnegut in Breakfast of Champions used the genre to question the accepted knowledge and sources of the culture. The use of metafiction or breaking the fourth wall in literature varies from that on stage in that the experience is not communal but personal to the reader and develops a self-consciousness within the character/reader relationship that works to build trust and expand thought. This does not involve acknowledgment of a character's fictive nature. Breaking the fourth wall in literature is not always metafiction. Modern examples of breaking the fourth wall include Ada Palmer's Terra Ignota and William Goldman's The Princess Bride.

Question: can you break the fourth wall in a book?
A: yes
