Where is the subtle animation on the medical pulse svg spinner coming from ?

Hello,

Thanks for your Kind Patience!

The Animation for the Pulse in the Medical Demo is coming from the following CSS Codes added in the demos/medical/medical.css File:
[ch_pre type="css"]#css3-spinner-svg-pulse-wrapper {
position: absolute;
overflow: hidden;
width: 260px;
height: 210px;
top: 50%;
left: 50%;
margin-top: -105px;
margin-left: -130px;
background-color: transparent;
animation: none;
-webkit-animation: none;
}

#css3-spinner-svg-pulse {
position: absolute;
top: 50%;
left: 50%;
margin-top: -105px;
margin-left: -275px;
}

#css3-spinner-pulse {
stroke-dasharray: 281;
-webkit-animation: dash 5s infinite linear forwards;
}

/Animation/
@-webkit-keyframes dash {
from {
stroke-dashoffset:814;
}

to {
	stroke-dashoffset:-814;
}

}

@keyframes dash {
from {
stroke-dashoffset:814;
}

to {
	stroke-dashoffset:-814;
}

}[/ch_pre]
