The dominant Edinburgh side powered eight points clear of Celtic at the summit of the Scottish Premiership to bolster their early-season championship claims and deepen the struggles around the Celtic team.
A superb goal from Kyziridis and Lawrence Shankland's penalty gave Derek McInnes' side a two-goal advantage that the reigning champions could not overcome.
The young defender - one of three youngsters in the Celtic starting lineup - scored an own goal in the early stages to put Hearts ahead at a energetic Tynecastle, and it was the youngster's infringement that led to the penalty.
Callum McGregor's classy first goal of the season had quickly cancelled out the first goal, and Benjamin Nygren almost put Rodgers' team in front, choosing placement over power and allowing Alexander Schwolow to save from close range.
But the unstoppable Hearts side seized control again to hand the visitors to back-to-back losses for the initial occasion since 2023.
It also gives the Edinburgh side a significant lead at the summit.
The last time they were so far clear was in the 2005-2006 season under their former manager, when they ended as runners-up - one of just four occasions that a team has failed to win the title after building such an advantage in the past 27 years.
The Hearts coach, whose Aberdeen side were second to Celtic on multiple times, has been at pains to downplay championship discussions, as the club seek their maiden league title since the 1960s.
Rodgers has seen it all before at the club - both flawless and stuttering starts to a season. He's never ended as runner-up.
But on the weekend's performance, this Edinburgh outfit showed they need to be taken seriously.
Hearts started with the confidence of a side undefeated in the league this season - the popular attacker poked a cross in for the striker to stab wide.
The Glasgow team didn't aid their cause with some uncharacteristic carelessness in possession and they buckled under their first real examination.
Claudio Braga's header was touched on to a post by Kasper Schmeichel and the follow-up from Shankland was turned into the net by the hapless defender, in for the injured Cameron Carter-Vickers.
The away side grew into the contest and started building moves. From a flowing attack, the midfielder released Tierney to square for McGregor, who slotted home.
Aside from the opportunity for Nygren, Celtic struggled to create much for lone frontman Jonny Kenny or his substitute Yamada amid the absence of injured forwards their key strikers.
The home team rediscovered their energy and versatility in creating chances in the opposition half. Kyziridis, a standout performer of the club's relationship with shareholder Tony Bloom's Jamestown Analytics, fired a low shot past the goalkeeper from the just outside the area.
Almost straight away, Murray fouled the midfielder in the inside right channel and Shankland scored. And it could've been an even more handsome win, had substitute Ageu not been denied by Schmeichel.
Celtic's second half was somewhat summed up in a couple of moments involving big-money recruit Engles.
The set-piece from Engles delivery was in stark contrast to his European display in the continental victory over their Austrian opponents and the national team player was then booked for a cynical foul.
The Hearts manager: "The effort from the squad is evident, the togetherness. That's not always enough to win games consistently.
"Our strength lies in, is skillful players. You're witnessing it from a lot of players who have been here before. Recent additions are eager to show that.
"We're in a positive moment at the minute, but it's only three points. It's crucial for us to keep winning. We've got much work ahead, loads to do. After the first two rounds is normally an indication of your standing."
The Celtic boss: "It's a really poor goal from our perspective. We failed to push up when the ball went back as a defensive unit so when they pass the ball, they should have players offside but didn't. We have got to do better with the attempt.
"Plenty of matches to play for. It's still so early. It's just nine matches. Clearly, being eight adrift is not what we would want. The comfort is there's numerous fixtures to play.
"We now have to focus on the here and now and look to find more consistency and more quality in our play."
The Glasgow club are back at home on midweek against newly-promoted Falkirk (evening kick-off). At the identical hour in the top division, Hearts are at their opponents' ground.
