10 Heart Attack Symptoms

5. Abnormal or Irregular Heartbeat

Sudden bouts of rapid and irregular pulse can be a symptom of a heart attack. This is particularly the case when accompanied by dizziness or lightheadedness. Erratic heartbeat, along with an increased number of beats per minute indicates a need for immediate evaluation. Though skipped heartbeats should be medically examined in the absence of other symptoms and if you're otherwise healthy, they aren't usually dangerous. People can confuse such fast and irregular heartbeat patterns with panic attacks.
