Figure 11From: Diastolic time – frequency relation in the stress echo lab: filling timing and flow at different heart rates Diastolic time and diastolic filling rate vs. cardiac index: summary data. Left panels: scatter plots demonstrating relationships between the diastolic duration time and the cardiac index, both at rest and at peak stress. Right panels: scatter plots demonstrating relationships between the diastolic filling rate and the cardiac index, both at rest and at peak stress. Green symbols: dipyridamole stress; blue symbols: pacing stress; red symbols: exercise stress. The substantial increase in the LV diastolic filling rate measured as volume per time suggests a large filling capacity during exercise (red symbols).Back to article page
