“…From the sensor's point of view, the change in heart rate should be mainly determined by the PP interval. However, since it is difficult for the ECG sensor to detect the P wave, the RR interval is usually used, as shown in the right ECG in Figure 1 [ 12 ].…”

Cervical vertigo refers to a clinical syndrome with sudden vertigo as the main symptom caused by the hemodynamic disturbance of the extracranial segment of the vertebral artery (VA) affected by cervical vertebral lesions. Small differences in pulse intervals in a patient’s continuous sinus rhythm are called heart rate variability (HRV). Heart rate variability refers to the small rise and fall of instantaneous heart rate between consecutive beats and is one of the most important physiological indicators of cardiac function. Small changes between successive beats reflect some information about the heart. So, it can be used to diagnose heart disease; its parameters can be used to identify emotions. Therefore, it is possible to use the characteristics of heart rate variability to find some patterns in the high-stress state and use the computer and ECG signals to describe the high-stress state. Since the ECG signal is a universal and objective model, it is practical and convenient to use it to describe stress states. Magnetic resonance angiography (MR angiography, MRA) is a noninvasive vascular imaging method that does not require intubation and contrast agents. At present, it has been widely used in clinical practice. In order to explore the changes of short-term heart rate variability and vertebral arterial magnetic resonance angiography (MRA) in patients with cervical vertigo and their clinical significance, this paper introduces two basic analysis methods of heart rate variability and commonly used MRA techniques, TOF technology. In the analysis of heart rate variability in patients with cervical vertigo, the statistical values of time and spectrum domain parameters were found to be lower in the experimental group than in the control group1. MRA showed that the abnormal rate of VA in the PCI group and the cervical vertigo group was similar. In the RMSSD index, the male experimental group reached 29, and the control group 1 reached 22.

“…Positional or rotational VBI causes vertigo, syncope or stroke, and is frequently associated with the VA compression. In contrast, SSS is typically detected by arm claudication or asymmetric arm blood pressure, but it can also be identified by vertigo or near syncope associated with head rotation [ 2 ]. Those mechanisms of pathogenesis are obviously different from each other.…”

Positional vertebrobasilar ischemia, also known as Bow hunter stroke, is typically caused by mechanical compression of the vertebral artery (VA). On the other hand, subclavian steal syndrome is incidentally detected by vertigo, syncope or loss of consciousness due to the steal phenomenon. A 61-year-old man suffered from near syncope when he turned his head to the left side. Although asymmetric arm blood pressure of the right dominant was observed, arm claudication was not detected. Computed tomographic angiography and magnetic resonance imaging revealed total occlusion of the left subclavian artery, hypoplasia of the right VA and an incomplete circle of Willis. Furthermore, carotid Doppler ultrasonic echography revealed retrograde blood flow of the left VA. It means that head rotation might occur in the left VA ischemia. An axillary-axillary bypass surgery was performed and ultrasonic echography showed anterograde effective blood flow of the left VA after the procedure.
