Echocardiography is the first step in imaging the right heart pulmonary circulation unit (RH-PCU), and the only one to allow its complete morphologic, functional, and hemodynamic analysis in all clinical scenarios. Right ventricular (RV) function is not only the consequence of its intrinsic contractile function (morphology and contractility) but also highly dependent on preload, afterload, and ventricular interdependence. Comprehensive echocardiographic examination of RH-PCU allows insight into intrinsic and extrinsic factors of RV function. Newer echocardiographic techniques allow for 3-dimensional evaluation of RV and detailed measurements of regional function using tissue Doppler or speckle tracking-based strain estimates.
超声心动图是右心肺循环单位（RH-PCU）成像的第一步，也是唯一能够在所有临床情况下对其进行完整形态学、功能和血流动力学分析的方法。右心室（RV）功能不仅是其内在收缩功能（形态和收缩性）的结果，而且还高度依赖于前负荷、后负荷和心室相互依赖性。对 RH-PCU 的全面超声心动图检查可以深入了解 RV 功能的内在和外在因素。较新的超声心动图技术允许使用组织多普勒或斑点追踪应变估计值对 RV 进行三维评估，并对局部功能进行详细测量。
