《心跳监护仪》音效
[Sound effect: Heart monitor in operating room with alarm]
[Duration: 10 seconds]
[Description: An electrocardiogram (ECG) monitor in a sterile operating room. Begins with a steady, rhythmic electronic beep (one beep per second), synchronized with a soft pulse waveform graphic sound (low-frequency thump). After 6 seconds of regular rhythm, the beeps become irregular (skipping, slowing), then suddenly a flatline alarm triggers: a continuous, piercing long tone (mid-high frequency, unwavering). No other ambient sounds except faint ventilator hum and distant metal tray clink.]
[Mood: Tense, medical, critical, urgent]
[Texture: Regular beep (mid, short) → skipped beat (silence) → irregular beeps (staggered) → flatline alarm (sustained, high, monotonous)]

正常心跳声采用合成器生成短促正弦波脉冲（音高约1kHz），每1秒一次，加入极轻微的低频“啵”声模拟心搏。
不规则阶段：先一次延迟（1.5秒），然后两次快速（0.5秒间隔），再延迟2秒，模拟心律不齐。
报警长鸣选用纯净的2kHz正弦波，持续至结尾，音量略高于正常心跳，不加混响以增强紧张感。
背景可加入极低的手术室环境底噪（空调、设备嗡鸣），但需极轻。
结尾长鸣可渐弱或突然切断（模拟医生关闭报警）。
