Takotsubo Cardiomyopathy: Sensitivity and Specificity

Introduction: also known as Broken Heart Syndrome. This represents a transient cardiomyopathy caused, we think, by a catecholamine surge. Classic findings on echocardiography are apical ballooning and a hyperdynamic base; the heart has the shape of an octopus trap, hence the name Takotsubo.

**Note that calculating probabilities from more than one finding is inherently inaccurate because findings are not independent. (For example, using two positive findings that share a common pathogenesis is likely to overestimate the true probability.)
