Normal vs Abnormal Heart Rhythm ECG Waveforms - Medical Illustration #3395148 (License: Personal Use)

The image displays two stylized red electrocardiogram (ECG) traces against a white background. The upper trace shows a regular, rhythmic pattern typical of normal sinus rhythm, with distinct P, QRS, and T waves. The lower trace exhibits an irregular, chaotic waveform, indicative of pathological conditions such as atrial fibrillation or ventricular ectopy. Both are simplified vector illustrations used for educational clarity rather than clinical diagnosis.

Used in healthcare websites, medical textbooks, patient education materials, and digital health platforms to illustrate cardiac rhythm differences. Matches user intent for understanding ECG basics, recognizing arrhythmias, or supporting telehealth explanations.
