Match ends, Heart of Midlothian 1, Rangers 3.
Rangers eased to a seventh consecutive victory over Hearts to ensure Celtic cannot clinch the Scottish Premiership title against Hibernian on Sunday.
It took Steven Gerrard's side only 15 minutes to make their early dominance tell through a Jermain Defoe finish.
Ryan Jack fired the second after being set up by Daniel Candeias.
Nikola Katic's half-volley from Candeias' cross after the break secured the points before Steven MacLean's headed reply.
Second-placed Rangers' second three-goal win over Hearts this month moves the visitors to within eight points of the reigning champions.
Hearts' chances of winning a Europa League place through their Scottish Premiership finish were further diminished as their run without a win over Rangers was extended to nine games.
Absences and Rangers formation undo Hearts
Both sides came into the game buoyed by 3-0 victories - Rangers beating Hearts then Motherwell by the same scoreline as the Edinburgh side against Inverness Caledonian Thistle in their Scottish Cup semi-final.
But Hearts' playing resources are being stretched to the limit and it showed from kick-off against a side who have been coping admirably without suspended top scorer Alfredo Morelos.
Youngsters Callumn Morrison and Aidan Keena had this week been ruled out for the season with knee injuries - and influential midfielder Peter Haring for a couple of weeks - and Hearts' preparations were further hampered minutes before kick-off.
Sean Clare was taken ill in the warm-up, meaning a rare start for Craig Wighton, with Clevid Dikamona added to the bench despite having initially been rested through injury.
While Wighton slotted straight into the Englishman's forward role, Hearts looked out of balance as they struggled to cope with a three-pronged attack that had rewarded Scott Arfield with four goals in his last two Rangers outings.
The reward for the visitors' early dominance came when Jon Flanagan slid in to dispossess a hesitant Wighton and Glen Kamara's superb through ball set up Defoe for a typically clinical finish from the former England striker.
Just as Hearts worked themselves back into the game, with Uche Ikpeazu and Wighton being wayward with their finishes, another slack moment in midfield handed Rangers a second goal.
Jack won the ball from Oliver Bozanic, who was deputising for Haring, and the midfielder followed up by collecting Candeias' pass to finish low into the far corner.
Hearts were caught out again, this time disputing a corner, as Candeias' cross found Katic ghosting in unmarked at the back post.
Fine saves from Rangers goalkeeper Allan McGregor denied Christophe Berra and Wighton before MacLean finished from a Jake Mulraney cross.
By then, however, Hearts were were well on their way to a third successive league defeat that will do nothing for their confidence as they look ahead to that cup final against Celtic.
Hearts contribute to own demise - analysis

Gerrard certainly appears to have found a system that brings the best out of his players.
It will be interesting to see exactly what the Rangers manager will do when Morelos becomes available again at the conclusion of his suspension.
While his ability in finding the target is unquestionable, will he fit into this team and allow it continue their run of results?
Hearts will look at the enforced change just prior to kick off as one possible reason for their demise. But this was just too easy for the Glasgow visitors.
Too often the ball was given away in Hearts' midfield and their back four time after time was cut open.
Mulraney was the only shining light in the home side, but the failure by his team-mates to find the former Caley Thistle winger meant chances in front of goal were few and far between.
Craig Levein said pre-match he was looking to build momentum ahead of the cup final in five weeks. Nothing could have been further from the truth after this game and, with a trip across the city to take on Hibernian next week, the task will be no easier.
'I hope the players haven't switched off' - Reaction
Hearts manager Craig Levein: "We've got a lot to play for between now and the cup final - including places in the team.
"I hope the players haven't switched off after reaching the final.
"Pressing in the way we tried means you go all in. There's no worrying about what's behind you. You just need to go and we were too safe in what we did.
"We didn't commit completely to it and the result is what you saw."
