Cardiac arrhythmia: Heart palpitations and other symptoms

Arrhythmia can produce a wide range of symptoms including palpitations, sensations of skipped beats or rapid forceful beats, dyspnea, chest pain or discomfort, syncope, fatigue, dizziness, and lightheadedness.

In bradycardia, the heart is unable to meet the body’s blood needs. This may cause fatigue, dizziness, syncope, lightheadedness, or cardiac arrest.

In tachycardia, the ventricles’ ability to pump blood efficiently to the body is compromised. This may cause palpitations, dyspnea, chest pain, dizziness, lightheadedness, and syncope.
