Symptoms of a heart attack include:
- Sweating, nausea, vomit and dizziness
- Extreme weakness and shortness of breath
- Rapid or irregular heartbeats
- Discomfort, pressure, heaviness, or pain in the chest, arm, or below the breastbone
- Discomfort radiating to the back, jaw, throat, or arm
- Fullness, indigestion, or choking feeling, may feel like heartburn
Usually, during a heart attack, symptoms last for thirty minutes or longer. The symptoms are not relieved by taking rest or by having nitroglycerin under the tongue. Some people might also have a silent myocardial infarction or a heart attack without symptoms. This is more common in people with diabetes.
