Monitoring of CRT-D devices during radiation therapy in vitro.

Background: Using of active cardiac medical devices increases steadily. In Europe, there were 183 implants of ICD and 944 implants of PM, 119 of biventricular ICD and 41 of biventricular PM, all per million inhabitants in 2014. Healthcare environments, including radiotherapy treatment rooms, are considered challenging for these implantable devices.

Monitoring biventricular pacing parameters depending on the left ventricle lead configuration.

Objectives: To evaluate whether pacing or sensing configuration has an effect on pacing parameters or their time progression. Three left ventricular (LV) pacing parameters were monitored - the LV pacing threshold, pacing impedance and intrinsic R-wave amplitude.

Methods: DATA WERE COLLECTED AT THREE INTERVALS: during implantation; between the second and fifth month after implantation (first follow-up); and between the eighth and 15th month after implantation (second follow-up).

Psychological intolerance to implantable cardioverter defibrillator.

Background: Implantable cardioverter defibrillators (ICD) are mobile implantable cardiac devices for immediate treatment of live threatening ventricular arrhythmias. However, these devices can affect patients, physiologically, psychologically and have effects on electrical devices.

Case Report: The case of a 61-year-old patient is reported.

Pulse wave variability within two short-term measurements.

Background: Pulse wave analysis permits non-invasive assessment of indices of arterial elasticity. Decreased arterial elasticity results in higher pulse wave velocity and therefore earlier wave reflection.

Aim: The aim of this study was to evaluate the short-term variability for measurement of surface arteries.

Surface artery volume pulse wave measurement - verification of a new method.

The aim of this paper is to prove the possible reproducibility of measurement with a new developed device for artery elasticity monitoring and determining the standard of major pulse wave parameters. As a measurement sensor, a conic probe with thin convex membrane was used. This technique allows setting an arbitrary pressure to a measured surface artery.
