Abstract:
The effects of passive and active orthostatic loads on the amplitude and temporal parameters of pulse waves were studied using an original computer assisted method of differential sphygmomanometry. Changes in the cardiac rhythm reflecting impairment of the autonomic regulation of the circulatory system and preceding neurogenic cardiovascular syncope were revealed and evaluated. Comparative analysis revealed similarity between these changes under conditions of both passive and active orthostasis, which confirmed the diagnostic value of differential sphygmomanometry.

Pulse rhythm
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...
Assessment of apical pulse
Assessing the apical pulse is a critical nursing procedure, particularly indicated for:
Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
Pre-Procedural Preparation
Assessment of blood pressure in brachial artery(one-step method)
Prepare for the Procedure:
Assessment of the Cardiovascular System I: Subjective Data
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
Inquire about symptoms...
Assessment of the Cardiovascular System III: Palpation
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
