Cardiac pacing in acute myocardial infarction complicated by complete heart block

Acute Myocardial Infarction Complicated by Third Degree Atrioventricular Block Treated With Temporary Pacemaker

“…During recent years pacemaker treatment has been universally employed and a convincing improvement in survival rate was expected. However, most investigations have reported lethalities of 28-50% during pacemaker treatment (9,13,15,16,17), which are of the same magnitude as found by Christiansen et al…”

Heart Block Complicating Acute Inferior Wall Myocardial Infarction

“…References 7,8,12,14,15,21,22,32,33. CHEST, 69: 5, MAY, 1976 ples of this discrepancy are the exceptionally low mortality of 20 percent without pacing described by Jackson and Bashour," while Rotman et all3 reported a 30 percent mortality despite pacing.…”

Premonitory sign of heart block in acute posterior myocardial infarction.

“…However, some cases of posterior myocardial infarction are complicated by unstable atrioventricular block (Guerot et al, I973), sometimes with ventricular pause or junctional escape rhythm with critical slowing of heart rate to 20 or 30 beats/mmi (Slama,Motte,and Coumel,I97I), justifying intracavitary pacing through a stimulating catheter (Watson and Goldberg,I97I), which clearly decreases the mortality (Schluger, Iraj, and Edson, 1970). A review of the electrocardiograms, including the right praecordial leads V3R and V4R, recorded in 94 cases of acute posterior myocardial infarction, was undertaken in order to identify the patterns preceding the appearance of atrioventricular block (Chaignon,I972).…”
