True Venous Pulse Wave

Pulse Wave Analysis and Pulse Wave Velocity

momanometer that provides arterial pressures (brachial systolic and diastolic pressure) is coming under question. The concerns extend well beyond the familiar issue of “white coat” hypertension, home and 24-h blood pressure recordings, and the phase-out of mercury based instruments. These concerns relate to the inaccuracy of all cuff devices for measuring pressure within the brachial artery, th...

Studies on the Venous Pulse

This investigation comprises a study of venous pulse, carotid, cardiographic, and heart sound records from twenty-one men with normal hearts. The heart sounds were recorded by the method of Einthoven. When correction is made for transmission, the first heart sound begins, on an average, 0.131 of a second before the c-wave of the venous pulse, and has an average duration of 0.128 of a second. Th...

2 Pulse Wave Analysis

Pulse wave velocity measurement

The article deals with the investigation of pulse wave propagation in arteries. A part of work involves also design and realization of devices serving for scanning of pulse wave by reflective photoplethysmography. The work describes a use of microcontroller serving for data flow control, communication and analog signal digitalization using integrated analog to digital converter.

Pulse Wave Analysis

Cardiovascular refers to the Cardio (heart) and vascular (blood vessels). The system has two major functional parts: central circulation system and systemic circulation system. Central circulation includes the pulmonary circulation and the heart from where the pulse wave is generated. Systemic circulation is the path that the blood goes from and to the heart. (Green 1984) Pulse wave is detected...
