In addition to a search for signs of instability, some manipulations can help when assessing and managing tachycardias. Specifically, actions that alter atrioventricular node conduction (“vagal maneuvers”) can help terminate or uncover a specific dysrhythmia [2, 10]. In a patient less than 50 years old, carotid body massage can help, although many fear doing this in the field because of poorly documented concerns about embolization. The Valsalva action can be used with carotid body (not carotid artery) massage in young patients or as the sole maneuver in those over 50 years old. We do not recommend other maneuvers, including ocular and rectal massage, ice packs or cold‐water dunking, or rapid inflation of pneumatic antishock garments.
