Zigzag heartbeat pulse line with one tall spike and a deep dip
About the Pulse black outline icon
A single continuous line traces a heartbeat reading: it runs flat, climbs to a tall narrow peak, plunges into a deep valley, then steps up to a smaller second peak before flattening out again. It works for health and fitness apps, hospital monitoring dashboards, ECG and vital sign displays, audio waveform controls and analytics panels that show activity spikes.
Sharp angular joints and one dominant spike give the stroke its rhythm, while the flat leads on both sides let it sit inline with text or numbers. It pairs with heart, stethoscope and activity icons. Match the stroke weight to nearby icons so the thin line does not vanish at small sizes.
This is the black outline version of the pulse icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
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.
