The focus shifts to identifying "matching" ST elevation in the same direction as the QRS complex in the right precordial leads, such as V1 and V2. The Diagnostic Challenge of STEMI in RBBB The primary challenge in managing STEMI in RBBB lies in the distortion of the typical ECG signs.
Decoding ECG Challenges: STEMI Patterns Obscured by RBBB
Prognosis and Right Ventricular Involvement The presence of RBBB during a STEMI often points to a specific location of the blockage, typically involving the right coronary artery. Misinterpreting the secondary repolarization abnormalities as acute injury can lead to unnecessary interventions and anxiety.
This results in a characteristic widening of the QRS complex and a specific shape of the waveform in the chest and right-sided leads, often masking the underlying myocardial activity. This frequently implicates the right ventricle, which can lead to unique hemodynamic complications such as reduced preload and hypotension.

Serial ECGs and the use of adjunctive imaging, such as echocardiography to assess right ventricular function, are essential tools in confirming the diagnosis and guiding further therapy. Right bundle branch block, on the other hand, is a conduction abnormality where the electrical impulse is delayed or blocked as it travels through the right bundle branch of the heart’s conduction system.
