DENNIS Ferguson would not be alive today if it wasn't for his wife Juliane's 000 call.

Earlier in the year, what the couple thought was just a blood sugar low resulted in Mr Ferguson going into cardiac arrest. If Mrs Ferguson hadn't dialled 000 when she did, paramedics wouldn't have been there in time to defibrillate him.

"I didn't know what was going to happen next, he was really dizzy and having things he hasn't experienced before,” Mrs Ferguson said.

"The 000 operator stayed on the phone until the ambulance got to the front gate, which I thought was great, it was reassuring.”

Mr Ferguson's story follows the paramedics' reminder for locals to phone 000 instead of driving to hospital.

"I thought if something happens and I'm driving then I'm not going to be able to do anything at all,” Mrs Ferguson said.

"My first instinct was to straight away ring 000 because that was going to give him the best chance of recovery.”

Quinn Coleman and Ian Turner were the paramedics who treated Mr Ferguson. Mr Coleman said in this case timing was everything.

"If that had happened maybe half an hour earlier, I think the outcome would have been very different,” he said.

"But for whatever reason these things happen how they happen and the timing was very much in your favour. Out-of-hospital cardiac arrests more often than not do not turn out well for a patient.

"In Dennis's experience it did turn out well for him and his family and I feel very privileged to be a part of that. I really hope he makes the most of his second chance at life.”

Mr Ferguson barely remembered the experience.

"I really didn't come to until about 8am that morning in hospital here. When I woke up I was normal,” he said.

"If somebody hadn't told me I'd had a heart attack I wouldn't know it.”

The couple struggled to verbalise how grateful they were to the paramedics.

"There was no hope for me being here today if you guys weren't there,” Mr Ferguson said.

"You can't put into words how great it is.”

However, Mr Turner insisted they weren't the ones to thank.

"Juliane is the hero in the whole scenario,” he said.
