**Scene 1 (0-4 seconds):** Close-up shot. An anxious woman, 30-40 years old, sits in a dimly lit room at night. She has her hand on her chest, her face filled with worry as she listens to her heartbeat. She looks down at her smartphone, the screen shows a Google search for "heart palpitations what is it". Her eyes dart around in fear. The atmosphere is tense.
**Scene 2 (4-10 seconds):** A sharp cut to Dr. Shakhanova Madina Shamilevna in a bright, clean office. She is wearing a doctor's coat, looks calm, confident, and friendly. She speaks directly to the camera, explaining what extrasystole is, using simple gestures. Animated icons of a heart with normal rhythm and one with an extrasystole appear next to her. She provides evidence-based medical information in a reassuring tone.
