Question
En faveur de quel mécanisme de trouble du rythme une sensation de "palpitations cervicales" plaide-t-elle au cours d'une tachycardie régulière ?
Answer

Tachycardie part réentrée intra-nodale atrio-ventriculaire

"[...] regular pounding in the neck during the palpitations distinguished atrioventricular nodal reentrant tachycardia from other causes of tachycardia [...]." - McGee

In studies of patients referred to electrophysiology specialists because of inter- mittent rapid palpitations, the symptom of rapid, regular pounding in the neck dur- ing the palpitations distinguished atrioventricular nodal reentrant tachycardia from other causes of tachycardia with a sensitivity of 20% to 92%, specificity of 83% to 100%, positive LR of 9.6, and negative LR of 0.5.17-19!

Question
Chez des patients ressentant des palpitations rapides paroxystiques, de quel rapport de vraisemblance positif la présence de la sensation de "palpitations cervicales" majore la probabilité diagnostique de tachycardie par réentrée intranodale atrioventriculaire ?
Answer

LR+ proche de 10 (à 9,6)

"[...] regular pounding in the neck dur- ing the palpitations distinguished atrioventricular nodal reentrant tachycardia from other causes of tachycardia with a sensitivity of 20% to 92%, specificity of 83% to 100%, positive LR of 9.6, and negative LR of 0.5" - McGee

Question
Chez des patients ressentant des palpitations rapides paroxystiques, est-ce la présence ou l'absence de la sensation de "palpitations cervicales" qui va le plus modifier la probabilité diagnostique post-test de tachycardie par réentrée intranodale atrio-ventriculaire ?
Answer

  • Présence utile (LR+ 9,6)
  • Absence moins contributive (LR- 0,5)

"[...] regular pounding in the neck dur- ing the palpitations distinguished atrioventricular nodal reentrant tachycardia from other causes of tachycardia with a sensitivity of 20% to 92%, specificity of 83% to 100%, positive LR of 9.6, and negative LR of 0.5" - McGee

Question
Devant une tachycardie régulière, quelle information sur la physiopathologie sous-jacente apporte une pression artérielle variable ? (brassard)
Answer

Dissociation auriculo-ventriculaire

"These findings include [...] and changing systolic blood pressure (usually detected with the blood pressure cuff)." - McGee

Parent (intermediate) annotation

Open it
Any finding of atrioventricular dissociation in patients with regular tachycardia indicates the rhythm is ventricular tachycardia. These findings include the intermit- tent appearance of cannon A waves in the neck veins, changing intensity of the first heart sound, and changing systolic blood pressure (usually detected with the blood pressure cuff).14
