During an attack or encounter with allergens or irritants, an allergic person's metabolism tries to come to the rescue by pumping out hormones. These hormones cause the heart to pump harder and for the blood vessels to tighten, which causes higher blood pressure, giving the body more energy and strength to fight against the perceived attack.
Normally, most people can tolerate these excess body hormones, but some people are more sensitive than others and their hearts over-react to the hormonal stimulus and literally go nuts, like your's does, and can cause weakness, breathing problems, feeling like one is going to faint, over-sweating, etc.
An approach would be to avoid any allergens or irritants or stimulants that excite the heart; and/or to take heart medications that attempt to block these excess hormones.
