(a) Electrocardiogram (ECG, case 1) findings upon admission. ECG showing atrial fibrillation (AF) and a complete right bundle branch block. (b) Chest X-ray (CXR) findings during AF tachycardia. CXR showing severe pulmonary edema and congestion.

An electrocardiogram (ECG) demonstrated AF and a complete right bundle branch block (Figure 1(a)). Her HR increased to 140 bpm and her chest X-ray (CXR) showed pulmonary edema and congestion (Figure 1(b)).
Patient (case 1) heart rate (HR) trends during treatment. The gap in the record is due to battery exhaustion.

Electrocardiogram (ECG, case 3) findings upon admission. (a) ECG showing atrial fibrillation (AF). (b) ECG showing sinus rhythm (SR). The heart rhythm often spontaneously alternated between AF and SR.

An 87-year-old woman was referred to our hospital for treatment of AF with palpitation and dyspnea (Figure 4(a)). HR was 151 bpm. Her heart rhythm often spontaneously alternated between AF and sinus rhythm (Figure 4(b)).
