ECG Heartbeat Waveform Illustration - Medical Diagram for Health Content #3558327 (License: Personal Use)

This maroon line drawing illustrates a simplified yet anatomically recognizable ECG trace, capturing the sequence of atrial depolarization (P wave), ventricular depolarization (QRS complex), and ventricular repolarization (T wave). The waveform ends with a solid circular dot, suggesting signal termination or lead connection. Its minimalist, hand-sketched aesthetic makes it suitable for educational or informational health content where clarity and visual appeal are prioritized over clinical precision.

Used on healthcare websites, patient education portals, medical blogs, or presentation slides to visually represent heart rhythm, cardiac monitoring, or basic physiology concepts. Matches user intent for understanding or explaining how an ECG works at a foundational level.
