Comparison of Squat-to-Stand Maneuver With Amyl Nitrite, Valsalva, and Exercise Stress Echocardiography in Inducing Latent Left Ventricular Outflow Obstruction in Hypertrophic Cardiomyopathy

Summary

The purpose of this study is to assess the effectiveness of squat-to-stand maneuver in eliciting left ventricular outflow gradients in patients with Hypertrophic Cardiomyopathy (HCM) compared to Valsalva, amyl nitrite inhalation, and exercise stress echocardiogram (ESE).
