Table 1 Measured quantities, their physiological correlates and diagnostic utility
Physical Measurement | Physiological Parameter | Diagnostic Relevance |
|---|---|---|
Peak Velocity | Peak Velocity | ↑ in Aortic Stenosis, ↓ in Heart Failure |
Minimum Velocity | Minimum Velocity | Negative with valvular dysfunction |
Peak Acceleration | Contractility | ↓ in Heart Failure |
Peak Deceleration | Peripheral Resistance | Indicative of vascular tone and development |
Velocity Integral | Stroke Volume and Cardiac Output | ↓ in Heart Failure |
