Changes of hemodynamics and echocardiographic features before and after changing the medication. In the switching therapy group, the medication was switched from 5-mg oral bisoprolol to the 8-mg bisoprolol transdermal patch in 5 cases (patient 1, patient 2, patient 3, patient 4, and patient 6). One patient who had already taken 7.5-mg oral bisoprolol (patient 5) was switched to the 8-mg bisoprolol transdermal patch. Patient 2 presented with symptomatic hypotension, so we reduced the dose of the bisoprolol transdermal patch from 8 mg to 4 mg. The systolic blood pressure of patient 1 decreased under 90 mmHg, but there was no symptom of worsened end-organ perfusion. HR = heart rate; BP = blood pressure; EF = ejection fraction; bpm = beats per minute
