Help understanding the meaning of a part in a song's lyric はち切れてしまいそう

I'm having trouble to understand this part from a song's lyric はち切れてしまいそう

Hope someone can give me a correct definition of this verb.




> はりつめた心が はち切れてしまいそう

First off, the verb applies to the "strained heart," and means "[to
burst](https://jisho.org/search/%E3%81%AF%E3%81%A1%E5%88%87%E3%82%8C%E3%82%8B)."
しまう implies something happened with surprise or unintendedly. [A ます-stem with
そう means something "looks like [...]."](https://www.tofugu.com/japanese-
grammar/verb-sou/) And so we have:

> It [will] look like my strained heart will burst.

Based on the lyrics, there is a very strong romanticism going on. Of course,
in a more applicable English translation, "look like" may be removed since
uncertainty is not common in English songs.
