Using impedance cardiography to examine changes in hemodynamic parameters during heart rate biofeedback
… arithmetic challenge, as HR, blood pressure, and impedance cardiography-derived measures were recorded. During the training sessions, the FB+ group received HR feedback and the FB-- group was not provided with HR feedback while playing the videogame. Results revealed that those in de FB+ group …

Resiliency and Autonomic Control of Cardiac Responses to Stress
… activation along a continuum of threat. Electrocardiography and impedance cardiography were collected before, during, and after these tasks to assess changes in autonomic functioning. Results from multiple regression analyses indicated that high levels of EC predicted increased vagal control …

Cardiovascular Activity During Laboratory Tasks in Individuals with High and Low Worry
… imagery. Heart rate, heart rate variability, impedance cardiography, and blood pressure indices were collected to assess task reactivity and recovery, particularly in relation to autonomic nervous system activity. The high worry group had significantly higher heart rates throughout the study. …

Moderating effect of a single aerobic exercise session on the cardiovascular response to a stressful procedure 45 minutes later
… pressor test. stroke volume was measured with impedance cardiography and total peripheral resistance (TPR) was estimated. SBP was significantly lower during the second minute of the anticipation period (F [1,29] = 4.75, p = .04) forty-five minutes after exercising compared to the attention …

Executive Function and Instrumental ADL Performance in Older Adults with Heart Failure
… series of psychosocial self-report measures, and impedance cardiography was conducted to quantify cardiac index. Executive dysfunction and reduced instrumental ADL performance was common in the current sample. Bivariate correlations revealed that cardiac index was not significantly associated with …

Assessment of Blood Flow in the Human Calf During Maximal Intermittent Dynamic Exercise Utilizing Impedance Plethysmography
… It is concluded that through the use of impedance cardiography (plethysmography) and the protocols utilized that: (1) differences between groups can be found relative to peripheral pulse rate, cardiac output, heart rate and stroke volume during rest; (2) differences can be found relative …

Individual Differences in Adults' Self-Report of Negative Affect and Effortful Control: Consequences for Physiology, Emotion, and Behavior During Regulatory Tasks
… derived from electrocardiogram (ECG) and impedance cardiography were recorded during each task and behaviors were coded using the Emotion Expressive Behavior Coding System. EC Group and NA Group were not significant for the majority of the physiological, self-report, and behavioral …

Cardiovascular Reactivity in Posttraumatic Stress Disorder and Depression
… pressure (SBP and DBP), heart rate (HR), and impedance cardiography derived cardiac output (CO) and total peripheral resistance (TPR) were utilized to examine CVR during speech preparation/delivery and math tasks. Between-group effects were observed during speech preparation - specifically, …

THE RELATIONSHIP BETWEEN AEROBIC TRAINING AND CARDIOVASCULAR RESPONSE TO EXERCISE
… capacity of untrained males (n=14) was examined. Impedance cardiography was used to examine stroke volume and cardiac output, whereas resting and peak blood flow were assessed using plethysmography. In Study 1 results showed that trained compared to untrained males had significantly lower resting …

PTSD Subtypes, Depressive Presentation, Dissociation, and Cognitive Appraisals and Their Impact on Cardiovascular Reactivity Responses to Stress
… arithmetic and public speaking‒were assessed via impedance cardiography and an automated blood pressure cuff. Multivariate regression revealed support for some hypotheses as significant relationships were found between reactivity and PTSD avoidance, PTSD arousal, and depressive withdrawal. No …

Valutazione degli effetti dell'esercizio fisico adattato sulla capacità fisica e sulla regolazione cardiocircolatoria in pazienti con sclerosi multipla
… recovery (CER) tests were measured by means of impedance cardiography (NCCOM 3, BoMed Inc., Irvine, CA). Also the difference between the PEMI and the CER tests was calculated to allow for metaboreflex response to be assessed. Evaluations were performed before training (T0), at the third (T3) and …

Valutazione degli aggiustamenti cardiocircolatori durante apnea statica e dinamica in apneisti d'elitè mediante l'uso di un dispositivo portatile
… collected from 12 elite divers by means of an impedance cardiograph adapted to the underwater environment. Mean arterial pressure (MBP), systemic vascular resistance (SVR) and arterial oxygen saturation (SaO2) were also assessed. Five trials were performed by the divers: head-out immersion …
