Serial electrocardiogram changes. (a) Normal sinus rhythm before the induction therapy (PR interval 206 ms, QTc 429 ms). (b) The 11th day of therapy, showing complete AV block (PR interval > 400 ms, QTc 395 ms). (c) Restoration of normal sinus rhythm after pacemaker removal (PR interval 192 ms, QTc 353 ms).

His baseline electrocardiogram (ECG) was normal (Figure 1(a)). ECG showed complete AV block with a heart rate (HR) of 40-50 beats/min (bpm) (Figure 1(b)). During follow-up, ECG showed normal sinus rhythm (Figure 1(c)), and echocardiogram revealed minimal pericardial effusion.
