Sites of congenital and surgical heart block as defined by His bundle electrocardiography.
Catheter recordings of His bundle electrograms were obtained in seven patients with congenital heart block (CHB) and in two with surgical heart block (SHB). In the latter two patients block occurred following total correction of tetralogy of Fallot. In six patients with CHB block occurred proximal to H. In one CHB patient block occurred in the His bundle with "split" H potentials. Intraventricu...
متن کاملHeart Block After His-Bundle Ablation
To investigate the electrophysiological properties of ventricular impulse formation after His-bundle ablation in 11 patients, incremental ventricular overdrive stimulation studies were performed. The studies, which were spread over a follow-up period of up to 601 days, were carried out invasively with temporary leads as well as noninvasively with the implanted pacemakers and chest wall inhibiti...
متن کاملBundle of His recordings in congenital complete heart block.
Six children, aged between 3 and 19 years, with congenital complete heart block without associated cardiac disease were studied by His bundle electrography. All were symptomatic with resting ventricular rates over 40 beats/min, and electrocardiograms that showed a normal axis and QRS complex. His bundle to ventricular activation was within the normal range in all and the block was proximal to t...
متن کاملStudies of heart block with His bundle electrograms.
A total of 24 patients with heart block revealed by scalar electrocardiography was studied using the His bundle electrogram. Four groups of disturbed conduction are described which include various types of heart block, partial and complete, at different sites, single and multiple, in the specialized conducting system. These are (i) intra-atrial block with delayed or blocked internodal conductio...
متن کاملHis Bundle electrogram in bundle-branch block.
SUMMARY Because a great majority of patients with chronic complete heart block have bilateral bundle-branch lesions, it becomes important to recognize earlier degrees of bilateral bundle-branch block. The H-V interval in the His bundle electrogram during unilateral bundle-branch block reflects the conduction primarily through the contralateral bundle branch, and thus the His bundle electrogram ...
