case_images: Electrocardiogram (ECG) showed a new onset left bundle branch block (LBBB) [Figure 1c] as compared to his prior ECG performed a month back before the current admission [Figure 1a]. On day 2 of admission, telemetry showed intermittent LBBB [Figure 1b] and eventually the LBBB was replaced by a narrow QRS complex [Figure 1d] with only supportive treatment.
