Have had 3 ablations but constant palpitations

It started in 2015, HR went to 205bpm, diagnosed atrial fibrillation. Medication and cardio conversion in the ER were performed and I was sent home. However, in the next few months I had many episodes of A-Fib. Very scary and the anxiety was intolerable. I had my first ablation in 2015 and was good for about a year. Then my heart started acting wierd again. But this time my HR would go up to about 160bpm and stay there. These episodes lasted about 20 minutes. As the year went on the episodes increased dramatically and within a 3-week period I was in the ER 9 times, and had 3 cardio conversions. I had another ablation and again it went well and I was in good shape. Diagnosis was now atrial flutter. Last year 2023 I had my 3rd ablation. But my EP had left our area, so I contacted him and flew to his new clinic. He is a truly amazing EP and I have great faith in him. The reason I am writing this is I get palpitations all the time. Probably about 3 or so every minute. Sometimes I can feel my heart actually hesitate for a second or two and I get dizzy and feel I am going to faint. I have just turned 80, I am very fit and exercised all my life. I walk 3 miles 4X/week at a brisk pace of 17:30mph. I lift weights 2X/week. I follow a mediterranean diet and drink good California wine:)
I am tired of the anxiety and try to put it out of my mind and live in constant fear that my heart is going to beat itself right out of my chest. Please tell me there are others out there like me because only you know what I am experiencing.
