Reverse valsalva
History
- First described in a 2020 case series from France by Gaudart, et al.[1]
- Initial data scant but promising with 10/11 cardioverting to normal sinus rhythm, including 4 who had failed the modified Valsalva maneuver
Set-up
- No assistant or items necessary
Steps
1) Have the patient exhale completely in a sitting position
2) Pinch nose and close mouth tightly
3) Attempt to inhale against resistance for 10 seconds
Carotid sinus massage
- Ideal duration of 15 seconds[2]
- Auscultate to rule out bruits in carotid artery before performing
- Perform ONE side at a time
- Perform with caution in elderly patients and those with a history of cardiovascular or neurologic events, though the complication rate is low[3]
Pediatrics
- Often successful with ice or ice-water application to face for at least 10 seconds (physiologically similar to mammalian diving reflex, and works best in infants up to 6 months of age)
