Q: What is the pattern called which is seen in v1 v2 in this ecg A: The V1-V2 morphology here looks like an rSr′ pattern often called incomplete right bundle branch block pattern if QRS is not clearly wide. In your tracing, V1 and V2 show: - a small initial r wave - a deeper S wave - then a terminal R′ the “rabbit ears” appearance That is the named pattern people usually refer to. Important caveat: a photo of part of an ECG is limited, so exact diagnosis benign IRBBB vs Brugada-pattern mimic vs lead placement issue, etc. needs the full 12-lead, QRS duration, and clinical context.
