An ECG performed on admission highlighted severe bradycardia (at a rate of 38 bpm), an absence of P waves and a regular ventricular rhythm, consistent with a diagnosis of AF complicated by complete AV block (Figure 1). Interestingly, pathological Q waves in the inferior leads (II, III, and aVF) along with prominent R waves in the anteroseptal leads (V1 and V2) were noted at present (Figure 1) and 12 months ago (Figure 2).

This was in stark contrast to her baseline ECG 12 months ago, which displayed an irregularly irregular rhythm with an absence of P waves and a variable ventricular rate (60-80 bpm), consistent with AF (Figure 2). Interestingly, pathological Q waves in the inferior leads (II, III, and aVF) along with prominent R waves in the anteroseptal leads (V1 and V2) were noted at present (Figure 1) and 12 months ago (Figure 2).
