Functional block in the intraventricular conduction system.
WHEN a normal impulse of supraventricular origin arrives at the His bundle, the entire specialized conduction system has had ample time to recover from the preceding response; the activation sequence of the ventricles and the resulting QRS complex are <'normal." When a lesion permanently damages one of the major divisions of the common bundle, the ventricular activation sequence is permanently ...
متن کاملConduction block in acute motor axonal neuropathy.
Guillain-Barré syndrome is divided into two major subtypes, acute inflammatory demyelinating polyneuropathy and acute motor axonal neuropathy. The characteristic electrophysiological features of acute motor axonal neuropathy are reduced amplitude or absence of distal compound muscle action potentials indicating axonal degeneration. In contrast, autopsy study results show early nodal changes in ...
متن کاملRetrograde conduction in complete heart block.
In complete heart block, absolute independence between atrial and ventricular activity does not always occur. Several mechanisms may be postulated to explain this phenomenon. One is incomplete atrio-ventricular block; another is atrio-ventricular synchronization and accrochage (Marriott, 1956; Schubart, Marriott, and Gorten, 1958; Ettinger, 1965). A third possibility rarely considered is unidir...
متن کاملConcealed retrograde conduction in complete atrioventricular block.
INCOMPLETE TRANSMISSION of impulses across the atrioventricular (A-V) junction has held a special fascination for many investigators.'14 Varied investigational techniques including venous pulse waves, standard electrocardiograms, and direct catheter electrode recordings from the cardiac chambers have been used to further the understanding of retrograde transmission of impulses into the A-V junc...
متن کاملPartial Conduction Block as an Early Nerve Conduction Finding in Neurolymphomatosis
BACKGROUND AND PURPOSE Neurolymphomatosis is a rare manifestation of hematological malignancy and is characterized by direct infiltration of the peripheral nervous system. The objective of this study was to identify the clinical and electrophysiological features of neurolymphomatosis. METHODS We retrospectively analyzed the medical records of 13 patients with neurolymphomatosis. Seven (54%) o...
