What are the signs or symptoms of heart arrhythmia?

Flip-flop: Most people who are troubled by minor heart arrhythmia report a flip-flop, fluttering, or pounding sensation. Unexplained loss of consciousness, usually without warning causing injury, is a tip off to doctors that a serious arrhythmia may be present.

Palpitations: Mostly patients report having palpitations, or feeling that heart is beating fast &/or strong. Some may feel lightheaded or dizzy. Occasionally serious arrhythmia may be associated with chest pain, and loss of consciousness (loc). Pt with palp and loc should seek medical attention immediately. Also, loc may be the only sign, especially during exercise, and needs immediate attention.
