简要总结

The purpose of this study is to learn if taking a drug called direct oral anticoagulant after an ablation procedure keeps blood clots from forming and lowers the chance of having a stroke in patients with ventricular tachycardia or arrhythmia (VT).

详细描述

Ventricular tachycardia (VT) or fast heart rhythm is a condition where the lower chambers (ventricles) of the heart beat too fast. This condition can be life threatening because these ventricles are the main pumping chambers of the heart. The fast heartbeat is caused by electrical impulses that travel incorrectly in your heart.

One way to treat VT is to have a catheter ablation procedure. A catheter ablation is a procedure that creates scar tissue in the heart to interrupt the electrical impulses that create irregular heart rhythms.

It is possible that the ablation procedure might cause a blood clot to form. The blood clot can stop blood flow to the brain and cause a stroke. When blood flow is interrupted to a certain part of the brain, that part does not receive enough oxygen. As a result of the stroke the affected areas of the brain are unable to function normally.

Direct oral anticoagulant (DOAC) is a blood thinning drug, also called an anticoagulant. It interferes with the body's natural blood clotting ability by inactivating a specific enzyme that the body needs to form blood clots.

Participation in this study will last about 30 days.
