Heart chart, for short crossword clue
126 Across · WSJ Crossword, September 25, 2026 · 3 letters
Explanation
The answer to “Heart chart, for short” is ECG. It appears as 126 Across in the Wall Street Journal crossword of September 25, 2026, a Friday puzzle titled “Rounding Error” by Jem Burch, and it fills 3 squares running left to right from row 21, column 7 of the 21×21 grid.
The shortening cue in the clue tells you to expect an abbreviation or initials rather than a full word. The entry begins with E and ends with G, and contains 1 vowel and 2 consonants. If you are working from the crossings, two or three confirmed letters from the Down entries should be enough to lock it in. Friday puzzles are the Journal’s contest crosswords with a hidden meta answer, so expect the rest of this grid to be pitched at the same level.
Past appearances
ECG has not appeared as an answer in any other WSJ puzzle in our index, which runs from May 2026 onward. It will be listed here the next time it turns up.
