Smartwatch heart rate during a jump scare

Living room lights off, only the TV flickering while I act like I’m not scared. Camera sits over my shoulder on a 50mm, then pushes in hard to the watch face as the jump scare hits. Dim practical lighting from the screen washes my wrist in blue-white glow; the OLED heart rate graph spikes almost too fast to read. I glance down, mouth open, no words, just the graph doing the talking. Handheld micro-shake, natural skin tones, quick whip pan back to the screen. Mockumentary reaction style, vertical crop. Wearable tech review vibe without any setup looking staged.
