WebJan 5, 2024 · The following is a simplified approach to naming the different types of anterior MI. The precordial leads can be classified as follows: Septal leads = V1-2. Anterior leads = V3-4. Lateral leads = V5-6. The different infarct patterns are named according to the leads with maximal ST elevation: Septal = V1-2.

WebSince the patient’s ECG showed typical findings of RBBB, the apparent ST-segment elevation in leads II, III, and aVF was considered to be part of QRS complex in RBBB . Likewise, the apparent reciprocal changes observed in leads I and aVL were also part of the QRS complex and not depression of the ST-segment ( Figure 1 ). The two bundle branches (right and left) are the electrical pathways that allow the cardiac electrical impulse to spread rapidly and evenly through both ventricles so that the beating of the heart is well coordinated.

WebNov 18, 2024 · In contrast, RBBB primarily affects the terminal phase of ventricular depolarization, producing a wide R' wave in the right chest leads and a wide S wave in the left chest leads (waveform 1A-B). These changes are due to delayed depolarization of the right ventricle, while depolarization of the left ventricle is not substantially affected.
