Myocardial infarction associated with Wolff-Parkinson-White syndrome

Masked ECG Changes in Wolff-Parkinson-White Syndrome Coexisting With Myocardial Infarction: A Case Report

“…Verani et al report a 49-year-old male case report with WPW syndrome presented with MI symptoms and the diagnosis was confirmed through ECG changes [ 4 ]. However, performing serial ECGs alone is time-consuming and can delay the diagnosis of MI, consequently postponing the primary coronary intervention necessary for myocardial salvage.…”

“…The prevalence of a WPW syndrome is estimated between 0.07-0.25 percent in the general population [ 2 , 3 ]. Diagnosing myocardial infarction (MI) via ECG in patients with WPW syndrome is often challenging because the abnormal activation sequence seen in WPW syndrome can obscure the typical ECG findings of MI [ 4 - 6 ]. The presence of Q waves can often be misleading in patients with pre-excitation and potential infarction.…”

Electrocardiographic abnormalities in a patient with pre-excitation and acute myocardial infarction undergoing percutaneous coronary intervention and ablation

“…The diagnosis of AMI in patients with WPW syndrome in outpatient clinics or emergency departments is challenging because the typical ECG findings of AMI can be masked by repolarization changes caused by pre-excitation. [1][2][3][4][5][6] Moreover, the abnormal Q wave (delta wave) in the ECG results of patients with WPW may easily lead to misdiagnosis of MI in clinical practice. 2 The key to the diagnosis of AMI in WPW syndrome is the serial evolution of ECG changes.…”

“…2 The key to the diagnosis of AMI in WPW syndrome is the serial evolution of ECG changes. 1,6 However, serial ECG is time-consuming and delays the diagnosis of STEMI and thus primary coronary intervention for myocardial rescue. In addition, ST elevation may be difficult to identify in patients with WPW syndrome because of existing secondary ST-T changes.…”

“…The electrocardiographic diagnosis of acute myocardial infarction (AMI) in patients with Wolff-Parkinson-White (WPW) syndrome is often difficult [1][2][3] because the abnormal activation sequence revealed through electrocardiography (ECG) in WPW syndrome may mask the characteristic ECG findings of MI. The presence of Q waves is often confusing for patients with pre-excitation and possible infarction.…”
