What is the mechanism of ‘Frog Sign’ in AVNRT?
- Atrioventricular nodal tachycardia -ventricles and atria are activated simultaneously at a rate of 160 to 180 beats/min.
- This dissociation causes the atria to contract against closed mitral and tricuspid valves.
- When atria contract against closed mitral and tricuspid valves it produces rapid and regular pounding in the neck.
- This is termed the frog sign.
