About the Pulse Waveform Line black filled icon
A circular frame contains a single horizontal trace that breaks into several sharp peaks and one deep downward spike before flattening out again, the way a monitor draws a heartbeat. It reads as vital signs, activity and live signal, so it suits fitness and health trackers, clinic and cardiology pages, server status or uptime widgets, audio level meters and analytics dashboards.
The line enters and exits flat at the same height, which keeps the waveform balanced inside the ring, and the peaks vary in height so the rhythm looks irregular rather than repeated. It pairs with heart, stethoscope and chart icons. Give it horizontal room so the trace does not compress.
This is the solid black filled version of the pulse waveform line icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
