“…While BPV has been widely studied in hypertension [ 34 , 62 ], less is known about its relationship with mental illness. Several studies have reported an increase in BPV in individuals with mental illness, which has been linked to an increase in their cardiovascular risk and target organ damage.…”

Background Mental illness represents a major global burden of disease worldwide. It has been hypothesised that individuals with mental illness have greater blood pressure fluctuations that lead to increased cardiovascular risk and target organ damage. This systematic review aims to (i) investigate the association between mental illness and blood pressure variability (BPV) and (ii) describe methods of BPV measurements and analysis which may affect pattern and degree of variability. Methods Four electronic databases were searched from inception until 2020. The quality assessment was performed using STROBE criteria. Studies were included if they investigated BPV (including either frequency or time domain analysis) in individuals with mental illness (particularly anxiety/generalised anxiety disorder, depression/major depressive disorder, panic disorder and hostility) and without hypertension. Two authors independently screened titles, abstracts and full texts. A third author resolved any disagreements. Results Twelve studies met the inclusion criteria. Three studies measured short-term BPV, two measured long-term BPV and seven measured ultra-short-term BPV. All studies related to short-term BPV using ambulatory and home blood pressure monitoring found a higher BPV in individuals with depression or panic disorder. The two studies measuring long-term BPV were limited to the older population and found mixed results. Mental illness is significantly associated with an increased BPV in younger and middle-aged adults. All studies of ultra-short-term BPV using standard cardiac autonomic assessment; non-invasive continuous finger blood pressure and heart rate signals found significant association between BPV and mental illness. A mixed result related to degree of tilt during tilt assessment and between controlled and spontaneous breathing were observed in patients with psychological state. Conclusions Current review found that people with mental illness is significantly associated with an increased BPV regardless of age. Since mental illness can contribute to the deterioration of autonomic function (HRV, BPV), early therapeutic intervention in mental illness may prevent diseases associated with autonomic dysregulation and reduce the likelihood of negative cardiac outcomes. Therefore, these findings may have important implications for patients' future physical health and well-being, highlighting the need for comprehensive cardiovascular risk reduction.

“…Given that we have already accurately measured individual heartbeats represented by R-R intervals in the anterior chest using IR-UWB radar in our previous study 17 , accurate measurement of individual R-R intervals from the carotid artery may open the possibility for noncontact measurement of the pulse transit time using radar. The pulse transit time contains information associated with the stiffness of the artery and has already been widely exploited to assess the degree of atherosclerosis and vascular aging 27,28 . Therefore, accurate measurement of the carotid pulse would widely expand the applications of IR-UWB radar in the clinical cardiovascular field.…”

There has been the possibility for respiration and carotid pulsation to be simultaneously monitored from a distance using impulse-radio ultra-wideband (IR-UWB) radar. Therefore, we investigated the validity of simultaneous respiratory rates (RR), pulse rates (PR) and R-R interval measurement using IR-UWB radar. We included 19 patients with a normal sinus rhythm (NSR) and 14 patients with persistent atrial fibrillation (PeAF). The RR, PR, R-R interval and rhythm were obtained simultaneously from the right carotid artery area in a supine position and under normal breathing conditions using IR-UWB radar. There was excellent agreement between the RR obtained by IR-UWB radar and that manually counted by a physician (intraclass correlation coefficient [ICC] 0.852). In the NSR group, there was excellent agreement between the PR (ICC 0.985), average R-R interval (ICC 0.999), and individual R-R interval (ICC 0.910) measured by IR-UWB radar and electrocardiography. In the PeAF group, PR (ICC 0.930), average R-R interval (ICC 0.957) and individual R-R interval (ICC 0.701) also agreed well between the two methods. These results demonstrate that IR-UWB radar can simultaneously monitor respiration, carotid pulse and heart rhythm with high precision and may thus be utilized as a noncontact continuous vital sign monitoring in clinical practice.

“…In this research, the blood pressure is represented by the carotid pulse [3][4] [5]. The carotid pulse records carotid artery pressure signals; the record is done by placing a sensor on the neck and is an alternative to seeing blood pressure signals [6] [5]. This carotid pulse is also useful for phonocardiograph (PCG) and can help identify a second heart (S2) and its components.…”

Heart disease is a very dangerous disease. Even today in Indonesia the disease ranks first as a cause of death. The purpose of this study is to design ECG, PCG, and Carotid Pulse on a computer with Delphi programming. The contribution of this research is that the carotid signal can be displayed on a personal computer monitor so that it can be viewed simultaneously with ECG and PCG signals. In order to intercept the carotid signal on the carotid artery on the surface of the neck, a piezoelectric sensor is used. In this study, the recording of the Carotid Pulse signal was carried out in the left upper neck area of the carotid artery with the help of a piezoelectric sensor. The primary circuit of the cardiac monitor consists of the non inverting amplifier, low pass filter 100hz, high pass filter 0,1 hz, summing amplifier and arduino microcontroller. Carotid Pulse Showed that the correlation between the pattern of the dicrotic notch (the D wave) in the carotid pulse and second heart sound (S2) was occurred simultaneously or just before the D wave pulse from carotid pulse for each respondent. The results of data collection from 10 respondents, were measured from the correlation between the Dicrotic Notch (pattern D) on the carotid pulse and S2 on the phonocardiograph occurred just before the Dicrotic Notch from carotid pulse. From the correlation measurement data obtained an average of 10 respondents, the interval between S2 and Dicrotic Notch was ±0.063 s.
