I also suffer from SVT and caffeine, in any form, can cause palpitations and irregularities - I'm not sure why you don't consider this important regarding your irregular heartbeats. My mom is in her upper 70's and she also complained of being abnormally tired. At her PCP's suggestion, she joined a gym and started with just walking the track, she says she now feels 20 years younger. Are you taking valium for insomnia and it's not working, or is it for something else? Susie is absolutely correct, make sure you get your information from a reputable site such as MayoClinic.com. I think you are causing yourself a lot of stress and anxiety that's not necessary. Trust your cardiologist.
