Can stress cause tachycardia and vertigo?

Yes, stress can lead to both tachycardia and vertigo. When a person experiences stress, the body's "fight or flight" response is activated, releasing adrenaline, which can increase heart rate (tachycardia). Additionally, stress can affect the vestibular system and lead to feelings of dizziness or vertigo. It's important to manage stress effectively to mitigate these symptoms.
