Key result
In a patient with dilated cardiomyopathy, the pressure gradient of mechanical alternans increased from 20 mmHg during sinus rhythm to 80 mmHg after a premature ventricular contraction.

Post-PVC augmentation of mechanical alternans may signal severe myocardial dysfunction in DCM; leaves open its value for risk stratification.
Case Report (n=1)
Absolute Event Rate: 80% vs 20%
Mechanical alternans, a sign of failing myocardium, can be significantly augmented following a premature ventricular contraction.
Kurisu et al. (2010) conducted a case report in Dilated cardiomyopathy (n=1). Premature ventricular contraction vs. Sinus rhythm was evaluated on Pressure gradient between strong and weak beats. In a patient with dilated cardiomyopathy, the pressure gradient of mechanical alternans increased from 20 mmHg during sinus rhythm to 80 mmHg after a premature ventricular contraction.
