Finding a Seattle cardiologist for a second opinion

Seeking either a recommendation for a cardiologist in Seattle or some pointers on how to find a good one.

This is for a friend in Anchorage who finds the specialists here to be less than informed. She's getting wishy washy treatment up here. After the doctor prescribed her a beta blocker, she was told to take it or not, it wouldn't make much of a difference. She basically has an extra beat every once in awhile. The cardiologist up here expressed concern – concern enough to call her on a Saturday, but then when she saw her, didn't give any further direction. So, she would like a second opinion.

We're going through a phase up here where you wonder about the local specialists. Another friend of mine was diagnosed with kidney problems, went to Virginia Mason in Seattle and found out her liver was shutting down, but her kidneys were doing okay. She had a reaction to the medication they had her on. That was never figured out up here. It's frustrating.
