RESUMO
MES de 87 derivações comparou duração média de ativação (XQRS) pré e pós-implante de MPBIV no VD, ântero-septal(AS) e VE de 28 pacientes,X =61anos, CF III-IV, FE<40, BRE/QRS=180,17ms e ICC, e grupo normal, em (1)BRE nativo, (2)BRE induzido-MP(VD); (3)MPBIV. (1) VD  AS (40,99msx43,62ms), VE=80,99ms (p<0,001). (2)VD > GNL (86,82ms,p<0,001), maior  AS/VE (63,41ms x 102.7ms, p<0,001). (3)VD > GNL e (1) (71,58ms X 35,1ms/40,99ms, p<0,001), AS  GNL e (1) (51,28msX50,14ms/43,62ms), VE=71,99ms  VD=71,58ms. Em pacientes com IC/BRE, pós-MPBIV, XQRS-VD  VE, próximos da AS, sugerem sincronismo ventricular. Ativação > de VD pode ser marcador na seleção de candidatos à ressincronização com MPBIV / 87-lead BSPM compared mean activation duration (XQRS) in RV, Anterior-Septum(AS) and LV of 28 patients, mean 61 years, CHF class III/IV, EF<40, LBBB QRS=180.17ms, and control group, in (1)baseline LBBB; (2)Induced- LBBB-PM(RV); (3)BIV-PM, pre- and post-BIV-PM implantation. (1) RV  AS (40.99msx43.62ms), LV=80.99ms,p<0.001). (2) RV > GNL (86.82ms,p<0.001), AS=63.41ms x LV=102.7ms, p<0.001). (3) RV=71.58ms > GNL and (1) (35.1ms/40.99ms,p<0.001), AS  GNL and (1) (51.28msX50.14ms/43.62ms), LV=71.99ms  RV=71.58ms. In patients with CHF/LBBB, post-BIV-PM, similar RV and LV XQRS, close to AS, indicate ventricular synchronism. Longer RV XQRS can be a marker to select candidates for CRT through BIV-PM...
