I was recently checked at my cardiologist. I had been in afib or aflutter and converted on my own. Only symptom was Tachycardia so that’s why I use the Kardia device daily. No shortness of breath. No known mitral valve or Aortic valve problems. If I have another episode I’ll definitely reach out to my PCP & cardiologist. I am being EXTREMELY careful of falling and know I probably would if it happened when I was standing.
