Immersion syndrome is also called as?
Immersion syndrome is also called as?
Show Hint
Instant reflex cardiac death on hitting water from vagal inhibition has this single-word synonym.
Updated On: Jun 24, 2026
- Hydrocution
- Wet drowning
- Dry drowning
- Secondary drowning
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: The key feature of immersion syndrome is instant death from a reflex cardiac arrest the moment the body hits the water, mediated by the vagus nerve.
Step 2: Because the heart stops via this vagal reflex rather than the lungs filling with water, the condition carries the alternate names hydrocution, submersion inhibition, and vagal inhibition. Triggers include sudden cold-water contact, feet-first duck diving, and epigastric impact.
Step 3: Wet drowning (water in lungs with froth) and dry drowning (laryngospasm-driven asphyxia) involve the respiratory tract, not a vagal cardiac arrest, so they are excluded.
Step 4: Secondary drowning is a late death after rescue, again distinct from the immediate reflex death of immersion syndrome.
\[\boxed{\text{Hydrocution}}\]
