- Anxiety, stress, or physical fatigue
- Hyperactive thyroid gland
- Excessive caffeine or alcohol use

- Low potassium and magnesium levels
- Valvular heart disease
- Rapid heartbeat or palpitations

- Shortness of breath and anxiety
- Chest discomfort

- Electrocardiogram (EKG)—Measures the electrical activity of the heart.
- Implantable loop recorder (ILR) is a small device that is surgically implanted under the skin of the chest and can be left in place for up to a year, or longer in some cases, in order to diagnose abnormal heart rhythms.
- Electrophysiologic study (EPS) is an invasive heart study where electrical wires are placed in the heart through a small puncture in the veins in groin. These wires map the electrical conduction system of the heart to locate the source of the abnormality.
- Echocardiogram or ultrasound exam of the heart to exclude structural heart disease.
- Blood tests to look for abnormalities in electrolytes and thyroid function.
- Calcium channel blockers
- Anti-arrhythmic medications
