Causes of Wolff Parkinson White Syndrome Based on TCM:
Doctors aren’t sure what causes WPW syndrome. The extra electrical pathway in the heart is present at birth, so it’s likely caused by some abnormality that occurs during fetal development. A small percentage of people with WPW syndrome have been found to have a gene mutation that is thought to be responsible for the disorder.

In a normal heart, the heartbeat is initiated by the sinus node in the upper right section of the heart muscle. This is where the electrical impulses that start each heartbeat begin. Those impulses then travel to the atria, or upper heart chambers, where the initiation of contraction occurs. Another node called the atrioventricular node, or AV node, then sends the impulse to the lower heart chambers called the ventricles where ventricular contraction occurs and the blood is pumped out of your heart. Ventricular contraction is much stronger than atrial contraction. The coordination of these events is essential for maintaining a normal, regular heartbeat and rhythm.

In a heart affected by WPW syndrome, however, an extra electrical pathway can interfere with the normal heartbeat. This extra pathway creates a shortcut for the electrical impulses. As a result, these impulses may activate the heartbeats too early or at the wrong time. If it’s left untreated, the abnormal heartbeat, arrhythmia, or tachycardia, can cause blood pressure, heart failure, and even death.
