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. Clinical Management and Immediate Actions If STEMI is suspected in a patient with RBBB, the immediate management pathway aligns with standard STEMI protocols, emphasizing rapid reperfusion.

Conversely, missing a true STEMI due to over-reliance on the baseline bundle branch block pattern can have devastating consequences. 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.
This combination creates a specific and high-stakes scenario where recognizing subtle ECG changes is essential to avoid misdiagnosis and ensure timely reperfusion therapy. 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.

This elevation typically follows a specific pattern corresponding to the area of the heart affected by the blockage. When a STEMI occurs, the heart muscle is deprived of oxygen due to a blocked coronary artery, and the presence of a baseline RBBB can significantly alter the appearance of the electrocardiogram (ECG).
