1. A system including a transesophageal echocardiogram (TEE) probe and configured for continuous monitoring of hemodynamic parameters () of a patient without repositioning the TEE probe, the system comprising:
an ultrasound transducer located in the probe and comprising a matrix array of piezoelectric elements, the ultrasound transducer configured to obtain a plurality of views, including a first view and a second view, of the patient's heart from a single position; and
one or more processors, operatively connected to the TEE probe, the one or more processors configured by machine-readable instructions to:
control the TEE probe to switch between the first view and the second view to interleave the acquisition of frames of the first view with frames of the second view in a manner that updates a first frame rate of the first view, the first frame rate being different from a second frame rate of the second view;
determine a new order for the interleaved acquisition of the frames of the first view and the frames of the second view, wherein the new order is determined using a scheduling algorithm and responsive, at least in part, to the updated first frame rate; and
determine, in real-time, a first hemodynamic parameter of the patient's heart using data obtained by the ultrasound transducer in the first view and a second hemodynamic parameter of the patient's heart using data obtained by the ultrasound transducer in the second view, wherein the first frame rate is selected based, at least in part, on the first hemodynamic parameter and the second frame rate is selected based, at least in part, on the second hemodynamic parameter.
