I read that multifocal pvcs are usually in a diseased heart. but my dr is not worries about mine. should i be concerned? can ablation be performed?

Not really: Forget ablation. You do not need it. Try to maximize your heart health by adequate rest at night. Take walks each day. Stop coffee and tea. Take adequate magnesium (500 mg per day), co- enzyme q-10, fish or flax oil, vitamins c (500 mg), carnitene, and vitamin e. Stress reduction is key, and relaxation training is advised. Cigarette smoking is verboten.

Doubtful: Pvcs can be normal, or marker for more serious disorder. Since they are multifocal, very unlikely to be able to find a location to ablate. If the heart is structurally normal, no coronary disease, electrolytes normal, and no drug influence, they may be ok as is.
