Insights
Diagnosing acute myocardial infarction (AMI) during cardiac pacing is challenging. Left bundle branch area pacing (LBBAP) may aid timely AMI diagnosis by providing physiological pacing advantages.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Diagnostics
Background:
- Electrocardiographic diagnosis of acute myocardial infarction (AMI) is complicated by cardiac pacing.
- Limited data exists on the diagnostic sensitivity of 12-lead ECG in patients with left bundle branch area pacing (LBBAP) during AMI.
Background:
Electrocardiographic diagnosis of acute myocardial infarction in the setting of cardiac pacing represents diagnostic challenge. There are no focusing data, neither reporting about diagnostic sensitivity of 12‑lead ECG with left bundle branch area pacing (LBBAP) during acute myocardial infarction (AMI).
Case Summary:
We present 12‑lead ECG morphology in a patient with permanent LBBAP during AMI.
Discussion:
Abnormal repolarization changes induced by ventricular pacing can lead to delay in diagnosis in patients with AMI. LBBAP and overall conduction system pacing may facilitate a timely diagnosis providing additional, still underestimated, advantages of physiological pacing of the heart.
