Abstract
Early detection and treatment are critical for patients with atrial fibrillation (AF), which is known to increase the risk of stroke and total mortality. In recent years, it has become possible to detect AF using electrocardiography and heart rate sensing. However, detection from pulse waveforms remains a difficult technology. Recent studies have shown that orthostatic hypotension (OH) increases the risk of developing AF. In this study, we focused on the effect of orthostasis on the autonomic nervous system and visualized the pulse wave characteristics of patients with chronic AF during orthostasis by simultaneous measurement of electrocardiogram (ECG) and photoplethysmogram (PPG).
