Is it correct to write out the sound of a heart beat as lub dub or are there other variations that are also acceptable?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.
There are different versions in different languages. In english I have seen thump thump, ba boom, ba bump and lub-dub. In India, it is "dhakdhak." In Italian, it's "tu tump."
Likewise, there are many others. Here is a link:
open "human sounds" and then "heartbeat."
