Notably, Thiem booked a spot in the championship clash by beating world number one Novak Djokovic 7-5, 6-7 (10-12), 7-6 (7-5), on Saturday.
But he was quickly back in the groove and held his nerve to rally from 4-0 down in the final-set tie-break, winning six successive points to earn two match points and taking the second of those.
Nadal has a 3-0 record against him but the last two matches were battles: Nadal won their 2019 U.S. Open final in five sets, and came from 5-1 down in the last set of their ATP Finals group match a year ago.
Previous year at The O2, Thiem won an epic group match, while Djokovic edged a five-set Australian Open final in January.
But in another astonishing twist, the 20-time Grand Slam champion played a sloppy game, allowing the Russian back into the match, and Medvedev won the eventual tie-break.
"It was for sure a mental battle", said Thiem.
"I felt really unusual until 5-4 for him in the second set, when he was serving for the match", said the fourth seed, who lost all three of his matches on his debut at the season-ending tournament past year. "I thought after winning the title in NY I would be more calm, but that was a mistake I guess". "But I guess it wasn't developed because we just did not have the cases like this previously". "I am really happy about it".
Nadal was quick to push credit over to Medvedev.
"The comment [that] got the most likes was, 'My mind is saying Dominic and Daniil will be in the final and my heart goes for Rafa and Novak, '" he said.
World number three Thiem was the better player in the first set, sealing it with an ace after breaking serve at 5-5.
After an aggressive start, Medvedev had three chances to break in game three, yet the Russian failed to take the opportunity to nose himself ahead. "He's playing great. I wish him all the best".
As for whether the Association of Tennis Professionals should bring in a code on domestic violence, like the ones used in American leagues such as the NFL and the NBA, Djokovic said "Obviously I'm not supporting any kind of violence".
Thiem confidently served out the first set and Djokovic looked hurried and harassed, as he faced another break point in the fifth game of the second set, but this time his opponent netted a forehand.
"I think it's super for tennis", he said.
As the curtain comes down on London's 12 years as host of the ATP Tour's prestigious season-ender, it would have been fitting for Nadal and Djokovic to face off for the 57th time in their glittering careers.
Nadal snuck an early break and behind some strong net play, hung on to a first set win. Medvedev squandered a point for a 5-1 lead and paid the price as Nadal hurtled back to stand on the brink of victory.
"We don't know what happened truly".
Medvedev is yet to drop a set and maintained his unbeaten record with a 6-3 6-3 victory over Diego Schwartzman, who did not win a match on his debut.
