"Even though we weren't in control of the game, we still felt we could be," Wade said. "We just knew that we had to fight all the way to the end.
"This is the kind of resolve this team is getting."
Arroyo converted six free throws in the final 22 seconds for the Heat, in sixth place in the Eastern Conference.
"I had a lot of confidence with my free throws," Arroyo said. "In those situations, I knew one point was not enough. Getting the two free throws each time was important."
The Raptors made 6-of-10 3-pointers in the third quarter, but then were only 6 of 20 from the field in the fourth period.
"We had a hard time getting open looks," Toronto coach Jay Triano said. "We would swing the ball and they would close out. They cranked it up in the fourth."
Andrea Bargnani and Jose Calderon each hit two 3-pointers during a 16-5 run midway through the third quarter. Calderon's second came with 5:14 remaining, capping the spurt and giving the Raptors a 72-55 lead.
Bargnani finished with 19 points and Calderon with 12. But Bargnani missed two open jumpers after the Heat took the lead in the fourth quarter.
"We had some open looks at the end and the ball just didn't want to go in," Calderon said.
The Heat played without starting center Jermaine O'Neal, who sat out with a hyperextended right knee. O'Neal was injured in the first quarter of Miami's victory at Milwaukee on Friday night.
Joel Anthony replaced O'Neal in the Miami starting lineup and shot 6 of 6 from the field for 13 points.
"I keep myself ready for whatever is going to happen," Anthony said. "I was just trying to do my job out there. Carlos and Dwyane did a real good job of finding me for some easy baskets."
Jack scored 11 points in the second quarter, helping the Raptors build a 49-43 halftime lead after the Heat led 26-23 at the end of the first period.
"The best part about this win was the fact things were not going our way and in the first half we were not mentally strong," Heat coach Erik Spoelstra said. "We were able to grind it out all the way to the end and our two captains [Wade and Haslem] were simply tremendous."
