What is heart attack ?
Heart attack, medically called myocardial infarction, is a serious heart condition wherein the blood flow to the heart gets blocked. Chest pain due to partial blockage of blood flow, commonly called angina, is a warning sign of a more severe heart attack, if left untreated. Complete blockage of blood flow due to a blood clot may cause serious results, including death.
What are the symptoms of arrhythmia?
The warning signs may vary depending on whether it is a mild or severe attack. Also, the signs may differ from person to person. They include:
- Uncomfortable pressure, pain, tightness, heaviness or squeezing kind of feeling in the middle of the chest region, lasting for a few minutes or in a pattern of going and coming back
- Chest pain or discomfort from the chest, spreading to the jaw, neck, arm, shoulder or back
- Feeling weak and light-headed (dizziness)
- Shortness of breath
