Síncope Vasovagal en Adultos Mayores de 40 Años con Pausas Asistólicas Documentadas — Cuando las Medidas de Estilo de Vida No Han Reducido las Recurrencias

Este protocolo se aplica a pacientes mayores de 40 años con síncope vasovagal caracterizado por evidencia objetiva de pausas asistólicas significativas o patrones cardioinhibitorios específicos, en quienes el manejo conservador inicial no logró una reducción significativa en las recurrencias del síncope.

Escenario Clínico

Enfoque Terapéutico (Parcial)

En pacientes altamente seleccionados que cumplen estos criterios, se considera una forma de estimulación cardíaca como opción de último recurso. El protocolo completo también especifica medidas adicionales para pacientes con susceptibilidad hipotensiva concomitante. La secuencia completa, los criterios de selección de pacientes y los pasos adyuvantes se detallan en el régimen estructurado.

Objetivo Clínico

Reducción de la recurrencia del síncope.

Cardiac pacing should be considered to reduce syncopal recurrences in patients aged >40 years, with spontaneous documented symptomatic asystolic pause(s) >3 s or asymptomatic pause(s) >6 s due to sinus arrest, AV block, or the combination of the two.
Cardiac pacing should be considered to reduce syncope recurrence in patients with cardioinhibitory carotid sinus syndrome who are >40 years with recurrent frequent unpredictable syncope.
Cardiac pacing may be considered to reduce syncope recurrences in patients with tilt-induced asystolic response who are >40 years with recurrent frequent unpredictable syncope.
Cardiac pacing may be considered to reduce syncope recurrences in patients with the clinical features of adenosine-sensitive syncope.
There is sufficient evidence that dual-chamber cardiac pacing should be considered to reduce recurrence of syncope when the correlation between symptoms and ECG is established in patients 40 years of age with the clinical features of those in the ISSUE studies.
Despite the lack of large RCTs, there is sufficient evidence that dual-chamber cardiac pacing should be considered to reduce syncopal recurrences in patients affected by dominant cardioinhibitory CSS.
Patients with hypotensive susceptibility should need measures directed to counteract hypotensive susceptibility in addition to cardiac pacing, e.g. the discontinuation/reduction of hypotensive drugs and the administration of fludrocortisone or midodrine.
