Bradycardia-dependent peri-infarction block.

Bradycardia-dependent peri-infarction block.

Bradycardia-dependent intraventricular block of the The latter showed a slowing of the ventricular debundle-branch type (paradoxical bundle-branch polarisation process after the first 0*05 to 0-06 s, block) is a recognised electrocardiographic finding lasting 0-08 to 0 09 s, and resulting in a wide QRS (Massumi, 1968; Sarachek, 1970). Similarly, focal of 0O18 s. The erythrocyte sedimentation ra...

Bradycardia-dependent bundle branch block in acute myocardial infarction.

Bradycardia-Dependent Bundle-Branch Block

Four cases of bundle-branch block (BBB) occurring with slow heart rates in patients with heart disease are presented. Recognition of bradycardia-dependent BBB is often difficult, and its differentiation from ventricular escape mechanism and from bilateral BBB requires careful analysis. A set of five criteria based on our own observations is presented with a review of the literature. The respons...

Tachycardia-dependent versus bradycardia-dependent intermittent bundle-branch block.

Analysis of I6 cases with intermittent bundle-branch block showing rate-dependence revealed the presence of 12 instances with tachycardia-dependent bundle-branch block, 3 with bradycardiadependent bundle-branch block, and one instance showing both types at two different occasions. Tachycardia-dependent bundle-branch block was explained on the basis of cycle length-recovery time relation and rev...

Recognition and significance of intraventricular block due to myocardial infarction (peri-infarction block).

Evidence of peri-infarction block was found in 39% of the electrocardiograms of 1,938 patients with definite evidence of myocardial infarction. It most commonly occurred acutely or within several days following infarction and was more common with recurrent infarction. Peri-infarction block infrequently disappeared and was associated with higher values for serum glutamic-oxalacetic transaminase ...
