Right bundle branch block and cardiac infarction.
It is the object of this paper to investigate the modifications of the electrocardiographic pattern of cardiac infarction caused by the simultaneous presence of right bundle branch block, and to describe the cardiographic signs on which the diagnosis of infarction can be made in the presence. of right branch block. The cardiogram of right branch block shows added changes characteristic of infar...
متن کاملBundle branch block in acute myocardial infarction.
The management of patients with acute myocardial infarction complicated by bundle branch block is a significant clinical problem and represents 8% to 13% of patients with acute infarction. This study reviews the records of 606 patients with myocardial infarction admitted to our coronary care unit. Forty-seven (8%) had complete bundle branch block. The risk of developing high-degree AV block in ...
متن کاملCardiac infarction with bundle branch block.
When cardiac infarction is complicated by bundle branch block, the electrocardiogram may or may not show the features characteristic of myocardial injury. Interference with conduction through the left branch of the bundle of His usually suppresses pathological Q waves and other RS-T segment or T wave changes in the standard and unipolar limb leads and in chest leads; it may then be impossible t...
متن کاملVentricular excitation in experimental bundle-branch block.
Multipoint 1 recording apparatus has been used to study the pattern of ventricular excitation in experimental bundle-branch block. After block, the wave of activation spreads uniformly from the contralateral ventricle across the septum to the free wall of the homolateral ventricle. Septal activation consumes more time than in the normal. Changes occur in the site and extent of early endocardia!...
متن کاملParoxysmal Heart Block in Bundle Branch Block.
When a patient is suspected of having Stokes-Adams disease the electrocardiogram is of critical importance, particularly in respect of the auriculo-ventricular (A-V) conduction time. Should this not be prolonged, the possibility of paroxysmal heart block remains, although the diagnosis of Stokes-Adams disease is uncertain without some degree of heart block recorded graphically. It is not known ...
