<unk>  revealed by laser Doppler imaging by digital holography of the eye fundus<unk>  revealed by blood flow pulse wave in the central retinal artery (red) and vein (blue) by laser Doppler imaging.<unk> s can be asymptomatic (the patient does not complain about anything). The subject may experience palpitations, a feeling of cardiac "pause". Taking (prolonged) pulse may result in a rhythm that seems irregular. Electrocardiography and laser Doppler imaging allow to visualize<unk> s. From their appearance, their location can be assessed. The Holter monitor allows to quantify them, to specify their characteristics and their repetition.
