Treatment of WPWS is based on the severity of symptoms experienced with the rapid heart rates. Drugs may be able to control the occurrence of any rapid heart rates. However, some individuals are not able to tolerate this type of therapy. Catheter ablation can be used to destroy the abnormal pathway, and prevent the rapid heart rates associated with the abnormal pathway. During VT, the heart does not pump blood as efficiently as it does during a normal rhythm.
Rapid contractions prevent the heart from filling adequately with blood between beats.
The result is less blood flow throughout the body. Ventricular tachycardia can result when a rapid rhythm originates in the ventricles. Besides occurring spontaneously, VT can also occur due a complication of heart surgery, heart attack, mitral valve prolapse, cardiomyopathy, and myocarditis. It can occur as a side effect of certain drugs, especially antiarrhythmic drugs. Changes in blood chemistry, pH, or oxygen level in the blood can initiate ventricular tachycardia.
