The high diagnostic rate of implantable loop recorder in the everyday clinical practice is in accordance with the findings in prospective clinical studies. This observation supports the early application of loop recorder in the diagnostic algorithm of syncope.
A 52-year-old woman is presented with repetitive transient loss of consciousness. Implantable loop recorder (ILR) recorded muscle artifacts during the generalized tonic-clonic seizures. Seizure was diagnosed and antiepileptic drug was started. The patient has been asymptomatic for 9 months. Orv Hetil. 2019; 160(29): 1143–1145.
Összefoglaló. Egy 78 éves férfi széles-QRS-tachycardiás esetét
mutatjuk be. A betegnél a pitvar-kamrai disszociáció igazolta a ritmuszavar
kamrai eredetét, amelyet a Valsalva-manőverrel több alkalommal is átmenetileg
meg lehetett szüntetni. A szerzők ismertetik a manőver lehetséges
patomechanizmusait, illetve felhívják a figyelmet arra, hogy a vagusmanőverre
megszűnő reguláris tachycardia nem jelent feltétlenül supraventricularis
eredetet. Orv Hetil. 2021; 162(12): 468–470.
Summary. A 78-year-old man is presented with wide QRS tachycardia
(WQRST). The ventricular origin of WQRST was confirmed by atrioventricular
dissociation. The Valsalva maneuver terminated the tachycardia repeatedly. The
authors discuss the possible mechanisms of Valsalva maneuver in the arrhythmia
termination. This case highlights that Valsalva maneuver or carotid massage
terminated tachycardia are not necessarily supraventricular tachycardia. Orv
Hetil. 2021; 162(12): 468–470.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
