Is there a prognostic relevance of electrophysiological studies in bundle branch block patients?

abstract：:An 81-year-old man presented with a large, infected right atrial thrombus that was refractory to anticoagulants and several courses of antibiotics. The risk of surgical removal of the thrombus, which was associated with a pacemaker electrode, was considered prohibitive. The patient was treated for 7 days with low-dose...
