The researchers used a device that measures beat-by-beat blood pressure and the underlying forces of heart rate, stroke volume and total peripheral resistance.
The hemodynamic variables [heart rate, HR; stroke volume, SV; and cardiac output, CO] were continuously recorded using an impedance cardiography device (PhysioFlow[R] PF07 Enduro[TM], USA).
We also compared the incidence of early remodeling in patients with pre-operative stroke volume >97 ml versus < 97 ml before aortic valve replacement.

This edition has new animations and audio and video clips of physiological processes and interviews with individuals in the field; new content on the research process and scientific inquiry, hormonal regulation of caloric intake, the use of lactate as a fuel, and mechanisms associated with different types of fatigue and muscle cramps; a new section on periodization to optimize training effects; a reorganized and updated chapter on ergogenic aids in sport; updated information on stroke volume changes during exercise, high-intensity interval training, interactions between resistance training and diet, and the relationship between protein intake and muscle synthesis; revised content on physical activity and disease, treatment guidelines, prohibited vs.
Patients with acute ischemic stroke who test positive for aspirin resistance had both larger stroke volume and increased severity, compared with patients without resistance, in an observational study of 311 patients at Korean centers.
The heart functions monitored by the researchers included right ventricular ejection fraction (RVEF), end-systolic volume (volume of blood at the maximum contraction point, ESV), and end-diastolic volume (volume of blood when at the maximum filling point, EDV), stroke volume and cardiac output.
