Integrate a subtle heartbeat (ECG) pulse line flowing through the design. Style should be minimal, elegant, and balanced with strong symmetry, suitable for modern hospital or healthcare branding. Use premium negative space techniques and a flat vector design. Color palette: deep medical blue, emerald green, and white. The logo should feel trustworthy, professional, and high-end. Centered on a white background, simple and clean, modern healthcare brand identity, scalable vector logo style.
