I have been having lots of problems with episodes of feeling dizzy, sweating, fatigue, palpitations, feeling like fainting. I saw a doctor Thursday who checked thyroid tests (I am on synthroid for hypothyroidism). This blood test was OK. I also had a ECG that showed my heart rate was a little lower (nurse didn't know exactly what it was) but that it wasn't low enough to cause my symptoms. I also was given an event monitor to use when I have these spells. Is it possible to have bradycardia and only have intermittent spells?
There are many mornings when I wake up when I feel terrible (weak, dizzy, nauseous). This morning I checked my heart rate before I left for work and it was 60 - which shouldn't be causing any symptoms, should it? I also have asthma and have difficulty telling if it is my asthma or something else going on. I have told many doctors that something else is going on besides my asthma, but they never take me serious.
Five years ago I was having problems kind of this this, and they did an exercise stress test and I had 3 beats of ventricular tachycardia. They did a few more cardiac tests but said everything was okay. I've also been diagnosed with pericarditis in the past.
I'm wondering if this sounds like it could be bradycardia and how low your heart rate has to be before having symptoms.
