Abstract:
The pre‐ejection period (PEP) and left ventricular ejection time (LVET) are easily measured by impedance cardiography (ICG). We hypothesized that the PEP/LVET measured by ICG would correlate with that measured by echocardiography, and that PEP/LVET measured by ICG would be useful for cardiac resynchronization therapy (CRT) optimization. Methods Newly CRT implanted patients were optimized by echocardiography. The PEP/LVET was measured by echocardiography and ICG in two different settings: optimized setting and right ventricle (RV)‐only pacing. Results The PEP/LVET was significantly decreased in the optimized setting compared with that in RV‐only pacing (0.62±0.13 vs 0.75±0.16, p 〈 0.05). The PEP/LVET values calculated by ICG and echocardiography were positively correlated ( r =0.553, p =0.003). Conclusion ICG was useful for the optimization of CRT.
