Sentence examples for hearts pacing from inspiring English sources

In Cx43+/− hearts, pacing resulted in a significant prolongation of ventricular effective refractory period and APD and significant diminution of Iss compared with unpaced Cx43+/− hearts.

However, in Cx43+/− hearts, pacing resulted in a significant prolongation of ventricular effective refractory period (VERP) compared with unpaced and paced wild-types and unpaced Cx43+/− hearts.

A spokesman for Medtronic Inc., a leading manufacturer of defibrillators, said the study was flawed because the patients who participated did not need their hearts paced for them.

WT, RyR2 p/s and RyR2s/s hearts paced at 10 Hz showed statistically indistinguishable VERPs of 63 ± 11.2 (n=3), 56.3 ± 8.4 (n=3) and 66.5 ± 18.5 ms (n = 3 hearts) respectively.

Finally, spontaneous after-depolarizations, previously implicated in the triggering of arrhythmias, were observed in hearts paced at both 8 and 10 Hz (n=2) (Fig. 7c).

Measurements of steady-state cardiac function were made at 20 cm-H2O preload and 75 mmHg afterload of hearts paced at 300 beats/min.

We resolved roles for early afterdepolarizations (EADs) and transmural gradients of repolarization in arrhythmogenesis in Langendorff-perfused hypokalaemic murine hearts paced from the right ventricular epicardium.

Espinoza et al. showed that TH in pigs decreased SV, ejection fraction and strain in hearts paced at 33°C, and concluded that TH may lead to systolic and diastolic dysfunction [ 42].

Left ventricular endocardial and epicardial monophasic action potentials were compared in isolated mouse hearts paced from the right ventricular epicardium perfused with hypokalaemic (3 and 4 m m [K+]o) solutions.

The observation that MAP duration from the epicardial surface of trained hearts was lengthened shows that the electrical remodelling we have previously reported in single myocytes [ 27] persists in whole hearts, paced at a physiological frequency and is not cancelled by the electronic loading of cell neighbours in the multicellular environment [ 41].

Following cannulation and perfusion the electrophysiological parameters of MAP waveform morphology, amplitude and duration reached a steady state within 10 min. MAP recordings in murine hearts paced at a basic cycle length (BCL) of 125 ms subsequently remained highly reproducible throughout the duration of all experiments.
