Educational Pearls:

• Hyperacute T waves can occur immediately and typical last less than an hour
• • Hyperacute T waves are typically broader than peaked T-waves, which are associated with hyperkalemia
• ST elevation which usually starts within an hour of the inciting event and can last up to a few days, and often follows the hyperacute T-waves
• Q waves can begin at the time ST elevation begins and can remain permanently
• T waves can invert before normalizing again days later
