Common symptoms associated with SVT include palpitations, light headedness, and chest pain. SVT may also cause confusion or loss of consciousness. Treatment Treatment of SVT is aimed at correcting the cause of the arrhythmia or controlling the rapid heart rates. SVT can occur because of poor oxygen flow to the heart muscle, lung disease, electrolyte imbalances, high levels of certain medications in your body, abnormalities of the heart's electrical conduction system, or structural abnormalities of the heart. However, if there is no apparent cause for the SVT, methods of controlling the periods of rapid heart rates are tried.
Medications are generally helpful in maintaining a normal heart rhythm.
