Wolff-Parkinson-White syndrome (WPW)

Preexcitation syndrome; WPW; Tachycardia - Wolff-Parkinson-White syndrome; Arrhythmia - WPW; Abnormal heart rhythm - WPW; Rapid heartbeat - WPW

Wolff-Parkinson-White (WPW) syndrome is a condition in which there is an extra electrical pathway in the heart. The condition can lead to periods of rapid heart rate (tachycardia).

WPW syndrome is one of the most common causes of fast heart rate problems in infants and children.

Ebstein's anomaly

Ebstein's anomaly is a congenital heart condition which results in an abnormality of the tricuspid valve. In this condition the tricuspid valve is elongated and displaced downward towards the right ventricle. The abnormality causes the tricuspid valve to leak blood backwards into the right atrium.

Holter heart monitor

During a heart Holter monitor study, the patient wears a monitor that records electrical activity of their heart (similarly to the recording of an electrocardiogram). This usually occurs for 24 hours, while at the same time the patient also records a diary of their activity. Health care providers then analyze the recording, tabulate a report of the heart’s activity, and correlate irregular heart activity with the entries of the patient’s diary.

Conduction system of the heart

The intrinsic conduction system sets the basic rhythm of the beating heart by generating impulses which stimulate the heart to contract.
