Medical illustration of a human heart with color-coded vessels next to three ECG strips showing normal, bradycardia, and tachycardia rhythms.

create a medical illustration of a heart with color-coded chambers (red for oxygenated, blue for deoxygenated). Next to the heart, add three simple ECG rhythm strips: one normal sinus rhythm, one bradycardia (slow), and one tachycardia (fast). Each strip should be labeled clearly with bold text: 'Normal', 'Bradycardia', 'Tachycardia'. White background, simple, infographic style for teaching students. See more
