IEEE SENSORS JOURNAL‚ VOL. 12‚ NO. 3‚ MARCH 2012 439 Film-Type Sensor Materials PVDF and EMFi in Measurement of Cardiorespiratory Signals— A Review Satu Rajala and Jukka Lekkala Abstract—In this paper‚ some recent results obtained with filmtype sensor materials polyvinylidenefluoride (PVDF) and electromechanical film (EMFi) are presented. The materials generate a voltage when they are mechanically deformed‚ however‚ because of their capacitive nature only the change of an external force

Uses of echocardiography Echocardiography (echo) can be used to evaluate your cardiac performance‚ the function of your heart valves‚ the thickness and motion of your heart walls‚ and the size of your heart chambers. An echo can help diagnose many heart conditions. Cardiac performance An echocardiogram can show how well your heart pumps blood (cardiac performance). To evaluate your cardiac performance‚ your doctor will mainly be interested in: • Your left ventricle‚ which pumps oxygen-rich

Good morning! Today I’m going to talk about artificial heart as one of the most significant invention in the history of humanity. An artificial heart is a device that replaces the heart. Artificial hearts are typically used to bridge the time to heart transplantation‚ or to permanently replace the heart in case heart transplantation is impossible. Since the late nineteenth century‚ scientists have tried to develop a mechanical device that could restore oxygen to the blood and remove

The heart is one of the most important organs in the body. All living things have a heartbeat‚ rather it be a healthy one or a not so healthy one. If your heart is not beating then I am saddened to tell you that you are dead‚ not that you would be able to hear me or care what I have to say. The four chambers consist of the right and left atrium and right and left atrium. Each of the chambers has valves. The tricuspid valve‚ mitral valve‚ pulmonary valve‚ and the aortic valve are their names. Their

Situation: Two patients in their 70s present to the office at different times today‚ each with documented heart failure: one diastolic and the other systolic‚ and both are hypertensive. First‚ discuss the difference between systolic and diastolic heart failure‚ providing appropriate pathophysiology. ACEI/ARBs are the only medications prescribed for CHF that have been found to prolong life and improve the quality of that life. EXPLAIN the mechanism of action of ACEI/ARBs and how they affect morbidity

INTRODUCTION Definition; It is a complex clinical syndrome that can result from any cardiac disorder that impairs the ability of the ventricle to deliver adequate quantities of blood to the metabolizing tissues during normal activity or at rest. Causes 1. Although the disease occurs most commonly among the elderly (80% of patients hospitalized with CHF are > 65 years of age)‚ it may appear at any age as a consequence of underlying cardiovascular disease. 2. There currently is no single
