“…33 All the physicians who agreed to participate attended preliminary meetings, under the supervision of central and local coordinators, during which they checked their sphygmomanometers and were trained in the standard methods of blood pressure (BP) [34][35][36][37][38][39][40] and anamnestic recording. Each GP agreed to enroll a random sample of 10 patients older than 64 years who had presented to his or her clinic for any reason: the first eligible patient was chosen each day until recruitment was completed.…”

“…This may be especially important in studies on the elderly because of the wide BP variability in this age group. [34][35][36][37][38][39][40] No other study had the opportunity to verify the prognostic significance of BP based on repeated measurements during such a long period. As expected, BP measurements taken during a long period-1 year-are more predictive than a few measurements taken 1 week apart (see relative risks in Figure 4 in comparison with Figure 2).…”

, MD; and general practitioners of SPAA Background: In young and middle-aged people, both systolic (SBP) and diastolic (DBP) blood pressure have a continuous, strong, and independent relationship with subsequent cardiovascular morbidity and mortality. These relationships are not well documented in older people and, until now, studies in the elderly do not provide homogeneous results on the importance of DBP compared with SBP as a cardiovascular risk factor.

“…The diagnosis must be established based on readings from the arm with the higher pressure, and the response to therapy monitored long-term using recordings from that arm. 2,3 Up to threequarters of individuals exhibit a difference in BP between right and left arms exceeding 10 mm Hg while seated or supine. Pressure tends to be higher on the right.…”

“…1 Accurate and reproducible measurement of blood pressure (BP) is essential and, to this end, extensive guidelines have been published on the appropriate use of the sphygmomanometer. 2,3 At the initial patient encounter, measurements must be made on both arms. The diagnosis must be established based on readings from the arm with the higher pressure, and the response to therapy monitored long-term using recordings from that arm.…”

To determine the effects of routinely selecting the nondominant arm for ambulatory blood pressure monitoring (ABPM) on estimates of patients' blood pressure (BP) and to evaluate the practise of using manual BP from one arm and ambulatory BP from the other on the estimation of white coat effect (WCE), an observational study was conducted in 10 volunteers, exhibiting an interarm resting clinic systolic BP (SBP) difference у10 mm Hg. The main outcome measures were: (i) average ambulatory SBP measured on right and left arm simultaneously during 24 h, and (ii) estimate of WCE derived, by current practise, as the difference between the referral clinic BP (the higher of the manual readings from both arms) and ambulatory non-dominant arm BP, contrasted with the WCE calculated as the difference

Abstrak -Telah dilakukan penelitian yang bertujuan untuk membuat sebuah model alat pemantau tekanan darah arteri pada lengan manusia, dengan metode NMR. Penelitian dilakukan dengan menempatkan pipa plastik (berdiameter 0,5 cm) datar memanjang melewati rongga antara kedua kutub elektromagnet yang memberikan kuat medan magnet (150 ± 5)x10 gauss, dan juga berada di sepanjang koil RF. Disamping koil RF itu terdapat pula koil penerima. Saat itu, air mengalir di dalam pipa pada kelajuan (4 ± 1)10 -1 m/s yang bersesuaian dengan tekanan 80 N/m 2 . Penelitian ini dilandasi oleh kenyataan bahwa 80% darah berupa air, dan molekul air mengandung atom hidrogen yang di dalam atomnya terdapat proton. Model ini dilandasi oleh kenyataan bahwa kelajuan alir darah di pembuluh arteri pada lengan (5 ± 1)x10 -1 m/s, dan diameter pembuluh darahnya juga 0,4 cm. Penelitian ini berhasil memberikan informasi, bahwa aliran air di dalam pipa plastik pada kelajuan, tekanan, dan kuat medan magnet di atas mampu memberikan frekuensi resonansi NMR sebesar 5,5MHz, dan koil penerima memberikan GGL induksi di CRO sebesar 18 mV.Kata-kata kunci: NMR, tekanan, air-darah, pipa pembuluh darah
