ABSTRACT
An echogram showing mitral valve alternans was recorded in a patient with advanced cardiomyopathy and pulsus alternans induced by premature ventricular depolarizations. Decreased left ventricular emptying by the weak beat was followed by blunting of the subsequent mitral valve E point, a finding compatible with a significant elevation of left ventricular pressure in early diastole. Both alternating systolic (contractile state) and diastolic (pressure and dimension) variables seemed to participate in the alternans phenomenon in this patient.
