Definition:
Preexcitation syndrome is a heart rhythm problem which is caused by an extra abnormal electrical pathway in the heart.
Diagnosis:
Preexcitation syndrome is in most cases detected by the presence of specific patterns on an electrocardiogram. Through an ECG, an extra pathway or shortcut in the heart may be revealed. A holter monitor and an event recorder may likewise help in the diagnosis. These will aid the doctor to determine and assess the heart rhythm in a 24-hour period. To further confirm the diagnosis or to pinpoint the location of the extra pathway, electrophysiologic testing may be recommended.
Treatment:
Among the treatments for preexcitation syndrome include strategies like particular maneuvers, intravenous and anti-rhythmic medications, and cardioversion. Radiofrequency catheter ablation and surgery are likewise treatment options for this condition.
Symptoms and Signs:
Most people with preexcitation syndrome experience these symptoms: a racing heartbeat, dizziness, a fluttering in the chest, lightheadedness, and fainting.
Causes:
The cause of this condition is the presence of an extra, abnormal conduction pathway, which directly connects the atria and ventricles.
