PUT A heart monitor on Stanley boss John Coleman and it wouldn't be good.
The manager needed a shoulder massage from his assistant boss Jimmy Bell as his blood pressure soared in the nervy, dying minutes of a 1-0 win.
Yelling at his players, head in his hands, turning away - it was all too much as York, who should have been out of the game, piled the pressure and stress on the frustrated boss.
"We don't do the simple things at times," said Coleman, shaking his head "I just don't understand it."
Yet once he had got over the tense last few minutes, the manager couldn't help but smile as Stanley recorded their fourth win in five games, two aways wins so far in this campaign, another clean sheet and are looking good in third spot in the table.
"It's like buses, you wait for a clean sheet since January, and then two come at once," said Coleman.
"My chairman is always telling me that the team that concede the least goals invariably win the league and that is something we have got to get together.
"We always fancy ourselves to make and take chances but at the other end it has been a bit of a problem sometimes.
"The chairman calls me a bit of a Kevin Keegan but I don't think I am that cavalier or gung-ho but sometimes we can make things a little easier for ourselves by being tighter at the back.
"But I think the benefit of full-time training should help us and we should improve. Now we have just got to build on it all."
The Reds were helped with their win by the sending off of York keeper Chris Porter after he raced out and flattened Ian Craney with only 18 minutes gone but then teenage YTS keeper David Stockdale did step in and have a stormer in goal for his ten-man side.
But Coleman had to single out some performances from his own players - especially goal hero Paul Mullin, with his fourth goal so far this season, and Craney, who was a constant thorn in York's side.
"Paul would be the first to admit that he doesn't take as many chances as he should and he didn't give us an easy night. The keeper did well to save from him twice. If one goes in we can rest a bit easier and pass the ball around abit.
"But it is a good finish for his goal. Paul is rapidly earning himself a reputation as one of the top strikers in the Conference - if not the best striker now that I have retired," joked Coleman.
"But he will get better with full-time football. He is leaner and sharper and if he could finish, he wouldn't be playing with us.
"And Ian is capable of unlocking defences and when games get a bit stale, you need someone like that."
For the first time this season, Coleman did change his starting eleven. Defender Steve Howson came in for the injured Steve Halford (calf) while Lutel James - after his international call-up for St Kitts - was dropped to the bench as Rory Prendergast made his first start of the season.
But it was York - with just one win in their previous 24 games - who started off brighter with a Lee Nogan header testing Kennedy and then the experienced Paul Groves tried his luck from 20 yards and the Reds keeper had to finger tip his header over.
Minutes after, former Blackburn player Darren Dunning tested the Reds defence with a cross which player-boss Chris Brass could not control in the six yard box.
Then the game erupted when Lee McEvilly sent Craney running through with Brass.
The defender tried to clear the ball but only sent it over his keepers head and Porter ran out and blocked the Stanley man on the edge of the area as Brass raced back to hook the ball clear.
It was a clear goalscoring opportunity and it was an instant red card which added to York's keeper problems as they already had Paul Crichton out after arguing with fans on Saturday.
But teenage rookie keeper Stockdale then entered the fray for his City debut and the script was written for him to be the hero.
And he was. He couldn't do alot about the free kick from Prendergast which skimmed the top of the crossbar or Craney's low shot which was inches wide.
But then he pulled off a stunning block to keep out a Prendergast effort from six yards after McEvilly had set him up - the whistle had blown for a foul but it gave the young shot-stopper the confidence he needed.
A Prendergast corner on 28 minutes was headed into Stockdale's hands by McEvilly, the keeper kept out a bullet Stuart Howson header from a Steve Jagielka corner and meanwhile the York City defence were throwing everything at the ball.
It seemed like it could be one of those days for Stanley especially when 10-man York came out battling after the break and piled on the pressure in front of their home fans.
Andy Bishop came close for York, Dunning proved a threat with his pace and Kevin Donovan made life uncomfortable for the backline.
Jagielka volleyed just wide before the Reds finally got the vital goal.
After patient build up involving Ged Brannan, Peter Cavanagh and Craney, Craney fired in a shot which was deflected and this came out to Jagielka who struck the ball goalwards and Mullin managed to get on the end of it and hook it into the net.
It looked like the floodgates would open then but sub Paul Cook curled an effort just wide, and Stockdale pulled off a superb save to keep out a Craney blast.
Cavanagh then set Mullin up but his sliding effort was saved by the feet of hero Stockdale as the Reds just couldn't get past the resolute defence.
And then there was almost agony as Groves was given a free header from a Donovan corner but luckily for the Reds it sailed over the bar.
There was still time for McEvilly to make it safe after he was set up by James but even he couldn't ease any pressure on his boss but rifling his effort well over the bar.
"The game hinged on the sending off," said Coleman. "We had a 20 minute spell where we were breathtaking after that and they were like a boxer covering their head.
"But I got a feeling that if we didn't score in the first half it would be difficult and give York their due, they came out very spirited in the second half and pegged us back.
"We actually scored against the run of play and they can count themsleves unlucky they didn't get a point although we missed a couple of chances."
Coleman had no qualms about the dismissal though.
"I do think, if the keeper hadn't stopped Ian, he would have got across him and scored anyway but it was a goalscoring opportunity and the letter of the law says he had to go. 15 years ago it is not a sending off but football has changed. Sometimes these decisions go for you and sometimes against you and this time it went our way.
"But their keeper was magnificent for a young lad. Some of his saves were unbelievable and he has made four good saves in the second half. He looked the part."
And the manager explained why he had decided to change a winning formula and give Prendergast the starting place.
"We just decided to give Rory the chance to get a few crosses in and allow players to get on the end of them. We always intended that we would make a change and put Lutel on and when he came on, he did really well. He was sharp, didn't give possession away and made a telling contribution.
"But I was pleased with everyone's contribition. We have now equalled the two away wins we had last season - and we can get better."
