Final answer:
The statement is true; in the event of a new or presumed new BBB in the setting of an AMI, the application of pacer pads is a precautionary measure to prevent further complications, as these patients are at higher risk for developing severe conduction disturbances that may require emergency pacing.
Step-by-step explanation:
The statement is True. If a patient has a newly acquired Left, Right, bifascicular or alternating Bundle Branch Block (BBB) in the setting of an Acute Myocardial Infarction (AMI), it is suggested to apply pacer pads. Bundle Branch Blocks can be a sign of significant heart block or damage, and the presence of a new or presumed new BBB in the setting of AMI is a Class I indication for the placement of temporary pacing in anticipation of possible progression to more severe conduction disturbances like third-degree heart block, which may necessitate emergency pacing.
Indications for temporary transvenous pacemaker placement, according to the American Heart Association (AHA), include new bundle branch block that can lead to sudden cardiac arrest due to progression to complete heart block. This preemptive approach is to ensure patient safety as the condition can quickly evolve into a life-threatening situation.
In medical practice, newly acquired conduction system abnormalities like BBB may require immediate intervention, and in the context of AMI, they increase the risk of high-grade atrioventricular (AV) block. Pacer pads should therefore be applied as a precaution in consideration of the risk of progression to complete heart block, which would require immediate electrical pacing to maintain an adequate heart rate and rhythm.
