Cardiac color ultrasound can detect atrial fibrillation, but it is not advantageous, and electrocardiography is recommended for clear diagnosis.
Cardiac color ultrasound examination can determine that there is atrial fibrillation by the performance in the examination, such as the absolute unequal spacing between the E peaks on the M echocardiogram, which determines the absolute irregularity of the heart rhythm; the disappearance of the A peak of the PW spectrum, which determines the loss of the contractile function of the left atrium, and so on.
Doing cardiac color ultrasound to detect atrial fibrillation requires adjustments to the examination method, such as measuring the EF value, which requires multiple measurements; it is not possible to judge the diastolic function of the heart by the E/A ratio, and so on.
However, it is not advantageous to judge atrial fibrillation by cardiac ultrasound. Definitive diagnosis of atrial fibrillation should be made by perfecting electrocardiogram and taking medicines reasonably under the guidance of doctors for preventing blood clots, heart failure and other treatments.
If there is any discomfort, you should consult a doctor in time and follow the doctor’s instructions for examination and treatment.
