Different electrocardiographic manifestations of the cardioinhibitory vasovagal reflex
Key result
Spontaneous cardioinhibitory reflex documented by implantable loop recorders was twice as frequent as tilt-induced reflex, with lone atrioventricular block present only during spontaneous events.

Michele Brignole (2008) conducted a review in vasovagal syncope (VVS). Tilt testing and implantable loop recorder (ILR) was evaluated. Spontaneous cardioinhibitory reflex documented by implantable loop recorders was twice as frequent as tilt-induced reflex, with lone atrioventricular block present only during spontaneous events.
