If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
a year ago, for about a week, I had sinus bradycardia at 50bpm, sinus tachycardia at 169bpm, occasional wrenching feelings in my chest accompanying 3 beats salvo premature ventricular contractions and premature atrial contractions
Everyone has these, the question is why, how many and for how long. What "condition" were you diagnosed with?
I don't have that kind of thing enough to notice. Do you mean everyone has odd heartbeats, but some can only be noticed with instrumentation?
