“…Besides wrist pulse, the deep‐lying internal jugular venous pulse (JVP) is considered another crucial parameter for the detection of conditions such as arrhythmias, right heart hemodynamics, or pericardial disease . Bao's group first demonstrated the monitoring of JVP by microhair‐based capacitive pressure sensors .…”

Wearable or attachable health monitoring smart systems are considered to be the next generation of personal portable devices for remote medicine practices. Smart flexible sensing electronics are components crucial in endowing health monitoring systems with the capability of real-time tracking of physiological signals. These signals are closely associated with body conditions, such as heart rate, wrist pulse, body temperature, blood/intraocular pressure and blood/sweat bio-information. Monitoring such physiological signals provides a convenient and non-invasive way for disease diagnoses and health assessments. This Review summarizes the recent progress of flexible sensing electronics for their use in wearable/attachable health monitoring systems. Meanwhile, we present an overview of different materials and configurations for flexible sensors, including piezo-resistive, piezo-electrical, capacitive, and field effect transistor based devices, and analyze the working principles in monitoring physiological signals. In addition, the future perspectives of wearable healthcare systems and the technical demands on their commercialization are briefly discussed.

“…It is the consequence of the transmission along the veins of the atrial pressure generated by the cardiac pump in the veins of the upper part of the body. [34][35][36][37][38] Some authors compare the jugular pulsation to a barometer inserted into the atrium that measures the pressure variations in the cardiac atrium. The typical jugular venous pulse is characterized by a sequence of five waves, three positive (a, c, v) and two negative (x and y).…”

“…The typical jugular venous pulse is characterized by a sequence of five waves, three positive (a, c, v) and two negative (x and y). [34][35][36][37][38] When the atrium begins the contraction, signaled by the p wave of the ECG, there corresponds to the positive and higher a wave in the JVP (Figure 9). The negative peak x is the consequence of the lowering of the cardiac septum when the ventricles begin the contraction.…”

Compliance is a characteristic of every deformable system. Compliance is very clear concept in physics and mechanics but in clinics, perhaps, is not the same. However, in veins compliance fits perfectly with the function of drainage of the venous system. Volumetric increase (dV) of the content is correlated with pressure increase (dP) inside the vein according to the equation C’= dV/dP. In humans 75% of the blood is located in the venous system, primarily because the molecular components of a vein media layer is significantly more compliant to that of arteries. This property is fundamental to understanding the change in blood volume in response to a change in posture. Measurements of venous compliance in clinical practice can be done by the means of ultrasound, as well as with the plethysmography. Ultrasound methods assimilate the cross sectional area to the volume of the vein, because it reflects the blood content. Changes in cross sectional area can be reliably measured in response to a change in posture, while pressure can be derived from the hydrostatic pressure changes. Venous compliance is of paramount importance also in pulsatile veins such as the inferior or superior vena cava and the jugular veins, where high resolution ultrasound may accurately derive the cross sectional area. Clinical implications of the mechanical properties of the venous wall are extensively discussed, including the need of dedicated venous stenting, which takes into account venous compliance as the main parameter of the venous function. In addition, venous compliance is the interpretative key for a better understanding of plethysmography curves, as well as of varicose veins and of their return to normal cross sectional area following ambulatory venous pressure reduction.

“…En un paciente de estatura promedio la aurícula derecha se encuentra a nivel del cuarto espacio intercostal y la distancia a la clavícula es de 12-16cm, una columna venosa yugular que aparezca por encima de la clavicula en el paciente sentado se considera IY [71,72]. Otras causas de ingurgitación yugular diferentes a IC son taponamiento cardiaco, pericarditis constrictiva, insuficiencia cardiaca derecha, infarto del ventrículo derecho, valvulopatía tricúspidea, tumores mediastinicos [74] y síndrome de vena cava superior, pero todas estas patologías cursan sin disnea paroxística nocturna [75]. La IY puede ser difícil de observar en pacientes obesos o con cuello corto [76].…”

Resumen: la insuficiencia cardiaca es un síndrome clínico de etiología multifactorial de alta prevalencia en la población mundial y latinoamericana debido al aumento en la expectativa de vida. Actualmente el diagnóstico de este se basa en los hallazgos de pruebas diagnósticas como el ecocardiograma o pépticos natriuréticos, pero es importante para el personal médico conocer e identificar de manera clara los signos y síntomas que presentan los pacientes con insuficiencia cardiaca, pues es una tendencia actual el desconocer datos semiológicos importantes que fueron descritos y refinados durante los siglos XIX y XX, y que ahora son validados por la medicina basada en la evidencia. Lo anterior cobra importancia pues el papel que debe tener la creciente tecnología no es acabar o desplazar el conocimiento clínico, si no ser una herramienta complementaria para el buen cuidado del paciente y así llegar al mejor desenlace posible.Este artículo pretende brindar datos basados en la evidencia para hacer de la clínica la parte fundamental del proceso diagnóstico y de la relación médico paciente. También intenta ser una guía útil para estudiantes de medicina o médicos que se desenvuelven en sitios con pocos recursos económicos, ya que la elección adecuada de un examen diagnóstico solo puede ser llevada a cabo mediante un buen interrogatorio y examen físico.Palabras clave: insuficiencia cardiaca; Diagnóstico; Signos y Síntomas; Colombia Copyright © Facultad de Ciencias de la Salud de la Universidad Tecnológica de Pereira. 1995-2017. Todos los derechos reservados ® Semiology and differential diagnosis of chronic heart failure Abstract: heart failure is a clinical syndrome with multifactorial etiology of high prevalence in the world and Latin American population due to the increase in life expectancy. Currently the diagnosis of this is based on the findings of diagnostic tests such as echocardiogram or natriuretic peptic, but it is important for the medical staff to know and clearly identify the signs and symptoms that patients with heart failure present, as it is a current trend To ignore important semiological data that were described and refined during the nineteenth and twentieth centuries, and which are now validated by evidencebased medicine. This is important because the role of growing technology is not to end or displace clinical knowledge, if not to be a complementary tool for good patient care and thus reach the best possible outcome.This article aims to provide data based on the evidence to make the clinic the fundamental part of the diagnostic process and the patient medical relationship. It is also intended to be a useful guide for medical students or physicians operating in poorly funded areas, as the proper choice of a diagnostic examination can only be carried out through a thorough examination and physical examination.Key words: heart failure; Diagnosis; Signs and Symptoms; Colombia Copyright © Facultad de Ciencias de la Salud de la Universidad Tecnológica de Pereira. 1995-2017.
