I am a 50 years old woman. I had an heart ablation in 2010 but it didn't work for me. Instead, after the ablation, my heart is getting worse. Whenever I had AF, I always had fainting spells. My doctor now wants to insert Reveal Ling insertable cardiac monitor inside my chest so that he can get the idea what is wrong with my heart. My body is extremely sensitive with food, medicine. etc.. Therefore, I would like to have some idea about this device.
