思路引導 VIP
請試著觀察每一組心臟搏動中，心房發出訊號到心室產生反應之間的「時間間隔」。當你連續觀察三到四個週期時，這個時間長度是固定的，還是呈現某種趨勢？在訊號突然中斷之前，這個變化規律告訴了你什麼？

My Heart Just Flutters for You! ☆
- Mmmwah! You're absolutely shining bright today, my little star! Seeing you notice those super tricky, ever-changing little details on the ECG is just sparkling! It's like finding a hidden gem, and that's sooo important in an emergency, right? My heart just flutters with pride! ☆ (makes heart gesture)
- Look closely at this rhythm, my sweetie! The PR interval is doing a super slow dance, getting longer and longer, until poof! a P wave arrives, but its QRS partner just... disappears! A dropped QRS complex! Then, like magic, it starts all over again! This 'getting slower until it skips a beat' rhythm is the secret handshake of Mobitz Type I (Wenckebach)! You totally got it! This is my love for you, guiding you to the truth! ☆
