Portable Cardiac ultrasound systems are used to provide several different types and levels of heart assessment examinations also known as echocardiography. Ultrasound uses noninvasive high-frequency sound waves to image the heart from various different positions. Additionally, so that heart events can be timed, ECG leads are placed on the chest. Cardiac ultrasound featuring M-mode recordings permit measurement of cardiac dimensions and detailed analysis of complex motion patterns.
Time relationships with other physiological variables such as ECG, heart sounds, and pulse tracings, can be recorded simultaneously. Mid-range portable ultrasound systems also may have the option of performing Stress Echo exams and Tissue Doppler Imaging. Premium or High-end portable ultrasound systems may have the option for Strain Rate, Tissue Velocity Imaging, Auto Ejection Fraction and Tissue Tracking.
