An arrhythmia can be silent, meaning you don't notice any symptoms. Your doctor may spot an uneven heartbeat during a physical exam.

If you have symptoms, they may include:

• Palpitations (a feeling of skipped heartbeats, fluttering, or "flip-flops");

• Pounding in your chest;

• Dizziness or feeling lightheaded;

• Fainting;

• Shortness of breath;

• Chest pain or tightness;

• Weakness or fatigue (feeling very tired);

• Anxiety;

• Blurry vision;

• Sweating.

Arrhythmia might not cause noticeable symptoms. However, a doctor may detect an arrhythmia during a routine examination or after requesting an electrocardiogram (EKG).

Even if an individual notices symptoms, it does not necessarily mean that they have a severe arrhythmia.

Some people with life-threatening arrhythmias may have no symptoms, while others with symptoms may have a light arrhythmia.

Symptoms depend on the type of arrhythmia, as follows:

1.         Symptoms of tachycardia

Symptoms of a rapid heartbeat include:

• breathlessness;

• dizziness;

• fainting or nearly fainting;

• fluttering in the chest;

• chest pain;

• lightheadedness;

• sudden weakness.

2.         Symptoms of bradycardia

Bradycardia can cause the following symptoms:

• angina, or chest pain;

• trouble concentrating;

• confusion;

• finding exercise more difficult than usual;

• dizziness;

• tiredness;

• lightheadedness;

• palpitations;

• shortness of breath;

• fainting or nearly fainting;

• profuse sweating.

3.         Symptoms of A-fib

When A-fib symptoms occur, they often have a rapid onset and may involve:

• angina;

• breathlessness;

• dizziness;

• palpitations;

• fainting or nearly fainting;

• weakness.
