Potassium level: This is a minor elevation of your potassium. By itself it is unlikely to cause any problems. You so not mention any need for potassium supplement so I assume you are not taking these. It does not cause a danger for your use of Flecainide. If you are concerned continue to follow your potassium level. Sometimes there are reasons why it is high and it is not a true reading.
