چکیده

UNLABELLED A 78-year-old women with a recent diagnosis of primary hyperparathyroidism presented with vague chest pain, and new onset left bundle block (LBBB) on the electrocardiogram (ECG) mimicking acute myocardial infarction (AMI). LBBB resolved without abnormal Q waves only after correction of hypercalcemia. The cardiac enzymes, including creatine kinase, creatine kinase-MB, and troponin-I were all within normal range. Hypercalcemia provoking ECG changes that mimic acute myocardial infarction is infrequently reported. To our knowledge, this is the first report of hypercalcemia-induced new onset LBBB mimicking AMI. Emergency physicians should include hypercalcemia-induced new onset LBBB on the ECG in the differential diagnosis of AMI. KEY WORDS Acute myocardial infarction; Hypercalcemia; Hyperparathyroidism; left bundle branch block.

Acute Myocardial Infarction with Bundle Branch Block (Rbbb or Lbbb) - Clinical Characteristics, Complications & Prognostic Significance - A Hospital Based Study

The occurrence of bundle branch block in acute myocardial infarction is important because it indicates that infarction may be extensive and may result in cardiac failure or death; however, the presence of bundle branch block is also important because it indicates seriously jeopardized AV conduction which could result in sudden extremely slow heart rates or asystolic arrest. The aim of the study...

Primary angioplasty in acute myocardial infarction with right bundle branch block: should new onset right bundle branch block be added to future guidelines as an indication for reperfusion therapy?

AIMS The current guidelines recommend reperfusion therapy in acute myocardial infarction (AMI) with ST-segment elevation or left bundle branch block (LBBB). Surprisingly, the right bundle branch block (RBBB) is not listed as an indication for reperfusion therapy. This study analysed patients with AMI presenting with RBBB [with or without left anterior hemiblock (LAH) or left posterior hemiblock...
