A minimalist tattoo design of an ECG heartbeat line with the text "Peerajchai" sitting directly on the ECG baseline. The ECG waveform should exactly match a real medical ECG rhythm, with sharp peaks and clean lines, not smoothed out. The line and text must be the same thickness, slightly bold, solid black ink only, with no shading or extra symbols. The font should be minimal sans-serif, modern, and simple. The design must be horizontal and centered, on a plain white background. High resolution, clean vector-style, stencil-ready, 3000px wide.
