Case ReportsHypothyroid cardiac tamponade presenting with severe systemic hypertension.
Hemodynamic data are presented which not only depict typical tamponade physiology, but demonstrate that hypotension may not necessarily be present with slow accumulation of pericardial fluid in myxedema patients. This case is unique in that severe hypertension, as part of the presentation of hypothyroid tamponade, has never been reported.

Case ReportsStress-induced polymorphous ventricular tachyarrhythmias in two brothers: unusual pattern of inheritance in the long QT syndrome.
Two brothers, 10 and 9 years old, are reported who were treated for years with antiepileptic drugs until the cardiac origin of their syncopal attacks was discovered. Our findings are consistent with the diagnosis of long QT syndrome, although no other family members are affected and only intermittent and mostly borderline QT prolongation could be found. Diagnostic difficulties and genetic implications are discussed.
