Wines sank to his haunches when nearing a passage of play late in the first quarter of Sunday's match at Adelaide Oval.
The Power star then slowly made his way to the interchange bench with about a minute remaining in the term.
Wines also experienced heart palpitations during a game against Melbourne in 2020.
He was also subbed out of that game and sent to hospital, where a heart irregularity was diagnosed.
The 2021 Brownlow medallist said he felt dizzy and nauseous during the game against Melbourne.
"It's more a heart rhythm issue that is pretty common in elderly people and elite athletes," Wines said at the time.
"'Once it was explained to me it was very reassuring and there's not too many long-term effects.
'The prognosis is really positive ... at this stage, it's not a big issue.
'It was (scary) during the game.
"And then after the game when I went off to hospital and they rushed me off when they saw something was wrong, but the ... staff, the cardiologist and nurses there were so reassuring and really put my mind at ease."
On Sunday, Wines remained on the Port interchange bench as the game against Hawthorn continued.
