Glowing electrocardiogram line on dark background

A single pale blue electrocardiogram line runs horizontally across a dark, softly graded background, forming repeated peaks and dips that suggest a heartbeat or medical monitoring display. The minimalist composition leaves most of the frame empty, which gives the graphic a clean, modern feel and plenty of negative space for design use. Cool cyan light stands out sharply against the near-black backdrop, creating a calm but clinical mood. The steady rhythm of the waveform makes the image suitable for health, wellness, and cardiology themes, as well as technology-oriented presentations. No people, devices, or labels are visible, keeping the visual simple and versatile. The smooth glow and restrained color palette add a polished, digital quality that works well for banners, headers, or editorial layouts focused on medical data and vital signs.
