ekg Vaz electro-cardio-graph? is it cardio? Why is it k? and why does this song have to have a sound that sounds like one and it's louder than the music and it gets faster and longer-lasting and once when I was half-asleep this sound started and it woke me up suddenly in a way that made my chest hurt a bit (with panic, really) because I expected that my home was in flames or that my room was about to explode.

Silence and its opposite mean death. 040402 ... no-one it is cardio... it can also be ECG. 040403 what's it to you? who go blather from
