New figures show it has taken an ambulance more than an hour to respond to a life-threatening emergency in the Shannonside region 16 times so far this year.
The worst response time was achieved in Leitrim, with a response time of 95 minutes.
According to guidelines from the Health Information and Quality Authority, an ambulance should arrive at the scene of life-threatening emergencies in less than 19 minutes in 80 percent of cases.
Yet new figures, released under the Freedom of Information Act, show this target isn’t being met in any of the Shannonside regions.
The response-time was reached in only 51 percent of the non-cardiac life-threatening emergencies in Roscommon, Galway and Mayo last December.
During the same month, it was met in only 55 percent of these incidents in the northwest, which includes Leitrim, and 54 percent in the midlands, including Longford.
These are among the worst rates achieved in Ireland.
Further statistics reveal that so far this year, on seven occasions, it has taken an ambulance more than an hour to arrive at a life-threatening emergency in Leitrim, the longest being 1 hour, 35 minutes.
There were six response times of more than an hour in Longford, the worst being 1 hour, 17 minutes.
In Roscommon, there were three calls of more than 60 minutes – the longest was 1 hour, 20 minutes.]
