Figure 1. (A) A 12-lead electrocardiogram (ECG) on emergency department presentation showing normal sinus rhythm at 93 beats per minute (bpm) with first-degree atrioventricular (AV) block, left-axis deviation, a PR interval of 294 ms, a QRS duration of 94 ms, and a corrected QT interval of 569 ms. (B) A 12-lead ECG on cardiac care unit admission (12 hours post electrocardiogram shown in (A) showing third-degree AV block with a ventricular escape rhythm of 41 bpm, left-axis deviation, a QRS duration of 124 ms (left bundle-branch block), and a corrected QT interval of 419 ms. (C) A 12-lead ECG on day 9 of antibiotic therapy showing normal sinus rhythm at 81 bpm with first-degree AV block, left-axis deviation, a PR interval of 432 ms, a QRS interval of 126 ms (left bundle-branch block), and a corrected QT interval of 473 ms.
