I am currently 66 and started having symptoms about 10 years ago, but the only were a couple times a year, and just dismissed them as stress related. In the last couple of years the symptoms would happen more frequently. So finally went to see a cardiologist, all my tests were great but I had an incident with the monitor they gave me and was diagnosed with svt. With all the heart arrhythmia this is probably the most benign one. I was active before and I will continue to enjoy life with the help of medication, I'm going to pass on the ablation procedure to see how the meds do and see if I can control the symptoms myself.
