Irregular heart rhythms can also occur in "normal, healthy" hearts. Whether your Ventricular tachycardia (VT) is associated with your heart surgery I can't tell and it is too early to know whether you need another EP study or what treatment may be needed. As you may know, an electrophysiology (EP) study is a test that records the electrical activity and the electrical pathways of the heart. This test is used to help determine the cause of heart rhythm disturbance and the best treatment. During the EP study, abnormal heart rhythm will be tested with different medications to see which one controls it best or to determine whether a cardioverter/defibrillator(ICD) is needed.
You may need an EP study for further evaluation if your VT is considered a sreious risk:
- To determine the cause
- To locate the anatomic location
- To decide the best treatment.
Hope this helps,
