Nursing v Tach treatment

Depending on the type and severity of your arrhythmia, and the results of various tests including the electrophysiology study, there are several treatment options. You and your doctor will decide which one is right for you.

Medications

Certain anti-arrhythmic drugs change the electrical signals in the heart and help prevent abnormal sites from starting irregular or rapid heart rhythms.

Follow-up Electrophysiology Study

To make sure the medication is working properly after two or more days in the hospital, you may be brought back to the laboratory for a follow-up study. Our goal is to find the drug that works best for you.

Implantable Device (Pacemaker)

All implantable devices or pacemakers work on "demand" and are used to treat slow heart rhythms. They are small devices that are implanted beneath the skin below the collarbone and connected to a pace wire(s) positioned inside the heart via a vein; this delivers a small electrical impulse to stimulate the heart to beat when it is going too slow.

Catheter Ablation

A technique pioneered at UCSF, radiofrequency catheter ablation destroys or disrupts parts of the electrical pathways causing the arrhythmias, providing relief for patients who may not have responded well to medications, or who would rather not or can't take medications.

Catheter ablation involves threading a tiny metal-tipped wire catheter through a vein or artery in the leg and into the heart. Fluoroscopy, which allows cardiologists to view on a monitor the catheter moving through the vessel, provides a road map. Other catheters, usually inserted through the neck, contain electrical sensors to help find the area causing the short-circuits. The metal-tipped catheter is then maneuvered to each problem site and radiofrequency waves — the same energy used for radio and television transmission — gently burn away each unwanted strand of tissue. When catheter ablation was first tried, direct current shocks were used, but researchers later developed the use of radiofrequency waves — a more precise form of energy. With radiofrequency catheter ablation, patients usually leave the hospital in one day, compared to open heart surgery, which requires a week stay and months of recovery.

For conditions like Wolff-Parkinson-White syndrome, in which a hair-thin strand of tissue creates an extra electrical pathway between the upper and lower chambers of the heart, radiofrequency ablation offers a cure. It has become the treatment of choice for patients with that disorder who don't respond well to drug therapy or who have a propensity for rapid heart rates.

Even in arrythmias that can be controlled with drugs, the procedure has been shown to be cost effective because it eliminates medication failures that require hospitalization. It also is an attractive option for elderly patients who are prone to suffer side effects from drug therapy and women of childbearing age who can't take medications because of potential health risk to the fetus.
