Hull councillors have pledged to examine the idea of creating an interactive map showing where defibrillators are located across the city.
The move came as Councillor Daren Hale announced a £10,000 grant from a fund he oversees as council leader to ensure more of the life-saving machines are installed at public buildings.
It follows the tragic death of Bransholme dad Gary Mackinder, 53, who died after suffering a cardiac arrest in the North Point shopping centre in June.

He was meeting his wife Julie in her lunch break when he suddenly collapsed.
Despite brave attempts by shoppers and staff to save him, he died in hospital three days later. At the time there was no defibrillator at the shopping centre.
The dad-of-four was on his way to a GP appointment after feeling unwell for several weeks. He had suffered a bout of pneumonia at Easter and had struggled with his breathing since then.
His sister Joanne Bainbridge subsequently raised over £5,000 through a GoFundMe appeal to buy new defibrillators for public use in Hull.
Making her debut full first council speech, Bransholme ward Councillor Jan Loft praised Mrs Bainbridge's fund-raising efforts and said it was time to plug gaps in the provision of the machines across the city.
She said: "I commend the Oliver King Foundation for donating a defibrillator to the North Point centre and the GoFundMe campaign organised by Mr Mackinder’sfamily which has already raised enough to fund three defibrillators in public spaces in Hull.
"Though there are public defibrillators in various places across the city, including some council premises and assets, there are gaps in the provision of publicly-accessible automated external defibrillators and at present there is no holistic mapping system listing all AEDs in Hull."
She secured cross-party support for a proposed roll-out of new debrillators across the city with more work set to take place with amateur sports clubs on how they can access the machines and use them properly.
In an emotional debate, Councillor Paul Drake-Davis broke down in tears as he spoke about his father-in-law's sudden death following a heart attack while on holiday.
He suggested approaching telecoms group KCOM about turning some of its old public telephone boxes into new-look defibrillator stations.
Deputy council leader Councillor Hester Bridges, who also chairs the city's health and wellbeing board, welcomed moves by the authority on the issue.
She said it was also vital to ensure additional training wasin place for people over the use of the machines and revealed talks were being held with the Yorkshire Ambulance Services over training options.
"At the end of the day, this is about saving lives," she added.
