Intra-His bundle block complicating acute inferior myocardial infarction.
نویسندگان
چکیده
The unexpected findings of atrioventricular block or delay in the His bundle and proximal branches are described in a 51-year-old man with acute inferior myocardial infarction with narrow QRS complexes. With the information from the His bundle electrogram, the site of atrioventricular block is precisely localized.

Long-term survival of patients with incomplete bundle-branch block complicating acute myocardial infarction.
Electrocardiograms and His bundle electrograms were reviewed in 28 patients with incomplete bilateral bundle-branch block complicating acute myocardial infarction. All had a His bundle electrogram at the time of pacemaker insertion; 10 had a second one. Of 23 patients with an initially abnormal HV interval (55 ms or greater), 15 died (65%), while only one died (20%) in the group of 5 with a nor...
متن کاملHistopathology of Heart Block Complicating
Histopathological studies of the conduction system were related to His bundle electrogram recordings in seven patients with acute myocardial infarction and atrioventricular (A-V) conduction disturbances. The three patients with inferior infarctions had normal width QRS complexes and delay or block of the impulses above the His bundle. Recent ischemic changes were present in the A-V node in two ...
متن کاملAcute inferior wall myocardial infarction associated with complete atrioventricular block and left posterior hemiblock.
Three cases of acute inferior wall myocardial infarction associated with complete atrioventricular block and junctional escape rhythm showing left posterior hemiblock are presented. The triad appears to consitiute a distinct syndrome. It is postuated that the subsidiary pacemaker is situated either in the bundle of His or the proximal part of the anterior division of the left bundle-branch.
متن کاملWenckebach block in the distal conduction system complicating a non-Q wave acute myocardial infarction.
A 75-year-old woman was admitted for severe retrosternal chest pain. Her past medical history revealed mild diabetes mellitus and bifasciscular block (left anterior hemiblock [LAHI and incomplete right bundle-branch block [RBBB]). The electrocardiogram was compatible with a subendocardial (non-Q wave) inferior and anterolateral AMI. This was characterized by new ST-segment depression and T-wave...
متن کاملSite of heart block in acute myocardial infarction.
SUMMARY Bundle of His electrograms were recorded in eight patients with acute myocardial infarction and heart block. Three patients with diaphragmatic myocardial infarction (DMI) and one with subendocardial infarction were characterized by slowing or block above the bundle of His and A-V junctional escape rhythms during periods of advanced or complete block. An additional patient with DMI had b...
