Wolff-Parkinson-White syndrome is characterised by attacks of rapid heart rate (tachycardia), which is shown in an electrocardiogram (ECG). In some people the ECG abnormality may be present without any symptoms such as tachycardia.
The heartbeat is regulated by electrical impulses that travel through the atria (upper chambers of the heart) to a knot of tissue known as the atrioventricular node, and then to the ventricles (lower chambers of the heart). Usually electrical impulses pause at the atrioventricular node before prompting the ventricles to contract.

What is Parkinson
Parkinson’s disease is a common, slowly progressive, neurodegenerative disease. It results from the degeneration of neurons in the substantia nigra, a region of the brain that controls movement. This degeneration results in a shortage of a neurotransmitter called dopamine, therefore, causing impaired movement. The first symptoms of the disease are usually seen later in life, 40 years or older. Parkinson’s disease is often called primary parkinsonism or idiopathic Parkinson’s Disease to distinguish it from other forms of parkinsonism.
