Bundle branch block in acute myocardial infarction.

Acute myocardial infarction and left bundle branch block.

Complete left bundle branch block often masks old as well as acute myocardial infarctions. However, a diagnosis of acute myocardial infarction in the presence of complete left bundle branch block can be made when the acute injury current is large enough to modify the secondary repolarization abnormalities of left bundle branch block. Under these circumstances the classical ST-T changes of an ac...

Effet of low-dose Aspirin on mortality of Acute myocardial Infarction

SUMMARY Between Aug. 1982 and March 1984, In a prospective, randomized trial approximately 24 hours after the onset of acute myocardial, infarction (MI), the influence of Low dose aspirin (120-150 mg/day, just during inhospital phase), on inhospital and post- hospital mortality rate was studied in 62 patients, and compared with control group. The two groups were comparable with regard to age,...

Acute Myocardial Infarction with Bundle Branch Block (Rbbb or Lbbb) - Clinical Characteristics, Complications & Prognostic Significance - A Hospital Based Study

The occurrence of bundle branch block in acute myocardial infarction is important because it indicates that infarction may be extensive and may result in cardiac failure or death; however, the presence of bundle branch block is also important because it indicates seriously jeopardized AV conduction which could result in sudden extremely slow heart rates or asystolic arrest. The aim of the study...

Acute myocardial infarction in the presence of left bundle branch block.

Background. The presence of left bundlebranch block on the electrocardiogram may conceal the changes of acute myocardial infarction, which can delay both its recognition and treatment. We tested electrocardiographic criteria for the diagnosis of acute infarction in the presence of left bundle-branch block. Methods. The base-line electrocardiograms of patients enrolled in the GUSTO-1 (Global Uti...
