Like in English, in ASL, the sign 'heart attack' is often interchangeable with other terms such as 'cardiac arrest' and 'heart failure'.
Heart attack, cardiac arrest, and heart failure are medically different things. Simply put, "The American Heart Association (AHA) describes the difference between a heart attack and a cardiac arrest as a circulation issue compared with an electrical problem." Ref Heart failure occurs when the heart muscle fails to pump as much blood as the body needs.
The signs HEART ATTACK refers to the blood flow to the HEART being blocked. Another sign HEART STOP or HEART+BEAT+STOP (cardiac arrest) refers to the heart stopping BEATS. HEART FAILURE (or HEART+WEAK+BEAT) refers to the heart not having enough power to pump blood flow to the body.
Search/Filter: Enter a keyword in the filter/search box to see a list of available words with the "All" selection. Click on the page number if needed. Click on the blue link to look up the word. For best result, enter a partial word to see variations of the word.
Alphabetical letters: It's useful for 1) a single-letter word (such as A, B, etc.) and 2) very short words (e.g. "to", "he", etc.) to narrow down the words and pages in the list.
For best result, enter a short word in the search box, then select the alphetical letter (and page number if needed), and click on the blue link.
Don't forget to click "All" back when you search another word with a different initial letter.
If you cannot find (perhaps overlook) a word but you can still see a list of links, then keep looking until the links disappear! Sharpening your eye or maybe refine your alphabetical index skill. :)
Add a Word: This dictionary is not exhaustive; ASL signs are constantly added to the dictionary. If you don't find a word/sign, you can send your request (only if a single link doesn't show in the result).
Videos: The first video may be NOT the answer you're looking for. There are several signs for different meanings, contexts, and/or variations. Browsing all the way down to the next search box is highly recommended.
Video speed: Signing too fast in the videos? See HELP in the footer.
ASL has its own grammar and structure in sentences that works differently from English. For plurals, verb inflections, word order, etc., learn grammar in the "ASL Learn" section. For search in the dictionary, use the present-time verbs and base words. If you look for "said", look up the word "say". Likewise, if you look for an adjective word, try the noun or vice versa. E.g. The ASL signs for French and France are the same. If you look for a plural word, use a singular word.
