Heart synchronized gamma - camera gating: displaying two heart cycles on one screen

Area of Science:

• Cardiology
• Medical Devices
• Hemodynamics

Background:

• Assessing hemodynamic status is crucial for managing acute myocardial infarction (AMI).
• Left ventricular ejection fraction (LVEF) is a key indicator of hemodynamic function.
• Current methods may have limitations in real-time visualization of cardiac dynamics.

Purpose of the Study:

• To introduce a novel method for evaluating hemodynamic status in patients with acute myocardial infarction.
• To present a new device designed for synchronizing cardiac signals and oscilloscope recordings.
• To improve the visualization of systolic and diastolic function during cardiac assessment.

Main Methods:

• Development of a device to synchronize the R-wave of the electrocardiogram.
• Control of a recording oscilloscope to capture cardiac cycles.
• Simultaneous display of systolic and diastolic phases on a single oscilloscope screen.

Main Results:

• The described method allows for a comprehensive evaluation of hemodynamic status.
• The novel device facilitates synchronized R-wave triggering and oscilloscope control.
• Visualization of both systole and diastole on one oscilloscope provides a clearer picture of cardiac function.

Conclusions:

• The presented method offers an effective approach to assess hemodynamic status in AMI.
• The new device aids in the precise visualization of cardiac cycle phases.
• This technique has the potential to enhance the clinical management of myocardial infarction patients.
