"My pulse was all up the shoot."
Soon she was hooked up to an ECG machine and before she knew it she was being sent to Rotorua Hospital.
"I thought at least I'll be home by 5pm and able to go into work the next morning."
Instead, doctors told her the unusual sensation in her jaw was actually a heart attack and she spent the night in hospital, before being transferred to Waikato Hospital for surgery to have a stent put in and relieve the blockage in her heart.
"They told me I'd had a heart attack and I thought, 'you mean to tell me that thing around my jaw was a heart attack?' I would never have known," she said.
More than 50 New Zealand women die of heart attacks every week. Heart Foundation medical director Gerry Devlin said there was a common misperception in society that heart disease was a "man's disease" and the campaign was dedicated to raising awareness of heart disease in women and getting them to look after their hearts.
He said symptoms of a heart attack could vary between men and women.
"Like men, the most common heart attack symptom for women is chest pain or discomfort. But women are more likely to experience other symptoms, such as discomfort in the upper back, sweating and unusual fatigue."
European women should get their heart checked from the age of 55 but Maori, Pacific and Indo-Asian women and those with known risk factors needed check-ups from the age of 45.
