我认为这个病例的诊断需行右心室心内膜心肌活检。

I believe that the diagnostic procedure in this case was a right ventricular endomyocardial biopsy.

目的了解右心室心内膜起搏室房传导(VAC)发生率及主要电生理特征。

Objective To investigate ventriculoatrial conduction (VAC) in endocardial pacemakers of the right ventricle take place rate of mainly electrophysiologic characteristics.

结果右心房、右心室心内膜起搏导线植入及两根心外膜起搏导线缝合均顺利，术后未出现严重并发症。

Results Right atrial and ventricular endocardial leads and two LV epicardial leads were implanted successfully without any serious complication.
