Atrial parasystolic trigeminy with sinus node echoes during wandering sinus node pacemaker in a patient with malignant lymphoma and hypertrophic cardiomyopathy.
A case of atrial parasystolic trigeminy associated with shifting or wandering pacemaker in a patient with malignant lymphoma and hypertrophic cardiomyopathy is presented, in which concomitant unsustained sinus node echoes during flattening of sinus P wave were observed. This is the first report to prove that wandering sinus pacemaker was one of the causes of sinus echoes.
