Esophageal ECG for transesophageal echocardiography

摘要

The medical imaging system uses a transesophageal probe 20 having an ultrasound transducer 21 for scanning the patient's heart and an atrial electrode 22 that generates an atrial electrocardiogram signal that is primarily indicative of electrical activity of the heart of the patient's heart. . The medical imaging system further uses a ventricular electrode 23 that generates a ventricular electrocardiogram signal that is primarily indicative of the electrical activity of the ventricle of the patient's heart. The medical imaging system further employs an electrocardiogram machine 30 that generates an electrocardiogram waveform based on the indicated electrical activity of the patient's heart and generates a cardiac gating signal that represents a periodic cardiac phase period of the electrocardiogram waveform. The medical imaging system further employs an ultrasound machine 40 that reconstructs an ultrasound image of the patient's heart, including time segments or entire periodic cardiac phase periods.
