Statewide Tele-ECG in São Paulo: A Ten-Year Program Experience (Preprint)

Horácio Gomes Pereira Filho, Bruna Affonso Madaloso, Eliana Mendonça, Conrado Pedroso Balbo et autres

BACKGROUND Introduction: Cardiovascular diseases are a leading cause of death in Brazil and globally. The 12-lead electrocardiogram (ECG) is a low-cost, non-invasive exam and widely available, but accurate interpretation might require specialized expertise. Tele-ECG can extend expert interpretation to resource-limited settings and …

Cardioneuroablation: don’t underestimate the posteromedial left atrial ganglionated plexus.

Ciro Ascione, Léa Benabou, Conrado Pedroso Balbo, Tsukasa Kamakura et autres

Introduction Cardioneuroablation (CNA) is a technique used to modulate cardiac parasympathetic tone in patients with sino-atrial (SA) and atrio-ventricular (AV) vagally mediated syncope. We describe the case of a patient who developed AV block after a first procedure of CNA, requiring a …
