Diagnosis of type 2 Brugada pattern: insights from a pilot survey.

Background: Differentiation of Type 2 Brugada Pattern (BP) from incomplete right bundle branch block or normal rSr' pattern can be insidious. The aim of this study was to assess interobserver and intraobserver agreement in the diagnosis of type 2 BP in a cohort of cardiologists with different skills.

Methods: We collected 14 ECGs with a positive terminal deflection of the QRS complex in lead V1 and V2 at the 4 intercostal space.

Functional atrial undersensing associated with device algorithm promoting AV conduction.

A 58-year-old woman received a dual chamber pacemaker (Medtronic) for sick sinus syndrome. Given intact AV conduction the Managed Ventricular Pacing mode algorithm (MVP) was programmed. The day after, she suffered from palpitations.

A Case of Brugada Pattern Migrant from Right Precordial Leads to Peripheral Leads.

Since the first report in 1992, Brugada pattern (BP) diagnosis is mainly based on analysis of the precordial leads. In cases with no clear BP evidence in the conventional right precordial leads (4 intercostal space), limb leads analysis resulted helpful in suspecting BP. Fluctuations within right precordial leads between the diagnostic ECG pattern and nondiagnostic ECGs are well known.
