Complete bundle-branch block complicating acute myocardial infarction.
TLDR
Bundle-branch block complicated 68 out of 806 cases of acute myocardial infarction managed in a coronary-care unit and was associated with a mortality of 56 per cent.Abstract:
Bundle-branch block complicated 68 out of 806 cases of acute myocardial infarction managed in a coronary-care unit and was associated with a mortality of 56 per cent. Twenty-five out of 48 patients with right-bundle-branch block, and 13 of 20 patients with left-bundle-branch block died. In 21 of the 68 patients complete heart block subsequently developed, and in 13 of these an idioventricular pacemaker failed to emerge. Bilateral bundle-branch block preceded the onset of complete heart block in 15 patients. Transvenous pacing electrodes were inserted prophylactically in the last 31 consecutive cases of bundle-branch block. This procedure was associated with a high proportion of life-threatening arrhythmias, and pacing did not reduce subsequent mortality in the nine patients in whom complete heart block developed.read more

TL;DR: In many patients MI with bundle branch block is associated with severe heart failure, however, this was not true for a majority of the patients, in whom therapy aimed at preventing morbidity and mortality due to the bradyarrhythmia of advanced AV block might be beneficial.

TL;DR: Patients who survive high degree block with MI should receive temporary and then permanent pacing, and patients without high degree AV block during MI who nervertheless have a high risk of sudden death may benefit from permanent pacing.

TL;DR: The National Registry of Myocardial Infarction 2 is a voluntary, prospective, observational registry that includes patients with acute myocardial infarction from all 50 states who were admitted to participating U.S. hospitals and the association of left and right BBB with in-hospital death was studied.

Disturbances of rate, rhythm and conduction in acute myocardial infarction: A prospective study of 100 consecutive unselected patients with the aid of electrocardiographic monitoring
TL;DR: It seems that: it is most likely to occur on the first day and is often preceded by ventricular ectopic beats or ventricular tachycardia, and it is estimated that at least 25 per cent of patients with this arrhythmia could be resuscitated.

The electrocardiographic diagnosis of bilateral bundle branch block in relation to heart block.
TL;DR: Several types of atypical right bundle branch block patterns described by the author earlier now appear to be caused by a combination of block of the entireright bundle branch and a part of the left branch.

Bilateral bundle branch block.
TL;DR: Cases in which the intrinsicoid deflection is delayed over both ventricles probably represent an association of true bundle branch block with an intraparietal conduction disturbance of the contralateral ventricle, which must necessarily prolong the A-V conduction time.

TL;DR: The Stokes-Adams syndrome, heart block complicating acute myocardial infarction, the electrophysiological complications of pacing, the appropriate roles of synchronous vis-a-vis-fixed-rate pacemakers, and the nature and possible applications of coupled and paired pacing were discussed.
