To assess the association between specific symptoms (palpitations, pre-syncope and syncope) and identification of clinically significant arrhythmias through the web-loop, which is a specific type of external event monitor. The correlation of arrhythmic symptoms and electrocardiographic record of significant arrhythmias using external events monitoring, which is known as web-loop, is still not determined in our population. Scanavacca MI, de Brito FS, Maia I, Hachul D, Gizzi J, Lorga A, Rassi A Jr, Filho MM, Mateos JC, D’Avila A, Sosa E Sociedade Brasileira de Cardiologia. It increases the accuracy of diagnosis when symptoms occur less frequently, i.e., weekly, monthly or yearly.( 2 2. 2005 150(5):1065.)Įxternal event monitor is a device that records ECG intermittently when activated.

Is ambulatory monitoring for “community-acquired” syncope economically attractive? A cost-effectiveness analysis of a randomized trial of external loop recorders versus Holter monitoring. Rockx MA, Hoch JS, Klein GJ, Yee R, Skanes AC, Gula LJ, et al. However, this record is not always easy and in case of sporadic symptoms, the continuous electrocardiogram (ECG) record for 24 hours (Holter) might not be efficient.( 1 1. The diagnosis and adequate treatment depend on electrocardiographic record during symptoms occurrence. In some patients these symptoms can be triggered by stress and anxiety, but not associated with rhythmic disorders. Palpitations, dizziness, pre-syncope and syncope are common complaints in physicians’ offices that might be related to cardiac arrhythmias. Monitorização fisiológica/instrumentação Monitorização fisiológica/métodos Arritmias cardíacas/diagnóstico Síncope O monitor de eventos pode ter importância na elucidação de sintomas de palpitações e síncope dos pacientes. ConclusãoĮm pacientes monitorizados pelo web-loop, não houve associação entre a presença de sintomas específicos e a detecção de arritmias significativas. Não houve associação entre a presença de sintomas e a detecção de arritmia significativa (OR=0,57, IC95%: 0,21-1,57 p=0,23). Em 11 pacientes (9,8%), foi detectada arritmia significativa na ausência de sintomas. O monitor de eventos registrou sintomas específicos em 74 (66%) pacientes, entretanto a associação entre sintomas específicos e arritmia significativa foi observada em apenas 14 (19%) deles. A associação entre presença de sintomas e arritmias significativas foi avaliada.
Arritmia significativa foi definida como taquicardia paroxística supraventricular, flutter e fibrilação atrial, taquicardia ventricular, pausas superiores a 2 segundos ou bloqueio atrioventricular avançado. Sintomas específicos foram definidos como palpitação, pré-síncope e síncope, presentes durante a monitorização. MétodosĮntre janeiro e dezembro de 2011, o web-loop foi instalado em 112 pacientes (46% mulheres, 52☒1 anos). Monitoring physiologic/instrumentation Monitoring physiologic/ methods Arrhythmias cardiac/diagnosis SyncopeĬorrelacionar sintomas arrítmicos com a presença de arritmias significativas por meio do monitor de eventos externo ( web-loop). Event loop recorder was useful to elucidate cases of palpitations and syncope in symptomatic patients. We found no association between major symptoms and significant cardiac arrhythmia in patients submitted to event recorder monitoring. There was no association between presence of major symptoms and significant cardiac arrhythmia (OR=0.57, CI95%: 0.21-1.57 p=0.23). Moreover, significant arrhythmia was found in 11 (9.8%) asymptomatic patients. Of these, in only 14 (19%) patients the association between symptoms and significant cardiac arrhythmia was detected. The web-loop recorded arrhythmic symptoms in 74 (66%) patients. The association between symptoms and significant arrhythmias were analyzed. Supraventricular tachycardia, atrial flutter or fibrillation, ventricular tachycardia, pauses greater than 2 seconds or advanced atrioventricular block were classified as significant arrhythmia. Specific arrhythmic symptoms were defined as palpitations, pre-syncope and syncope observed during the monitoring. Methodsīetween January and December 2011, the web-loop was connected to 112 patients (46% of them were women, mean age 52☒1 years old). To correlate arrhythmic symptoms with the presence of significant arrhythmias through the external event monitoring (web-loop).
