Pericardiocentesis can resolve intractable ventricular tachycardia ('electrical tamponade') secondary to large pericardial effusion in Dressler's syndrome.
May support pericardiocentesis in refractory VT with effusion; hypothesis-generating for electrical tamponade.
Post infarction pericarditis, Dressler's syndrome is a well-recognized condition, but its incidence has decreased in the present interventional era due to early reperfusion strategy. We encountered an unusual association of large pericardial effusion secondary to Dressler's syndrome and intractable ventricular tachycardia that reverted upon pericardiocentesis. We coined a term “electrical tamponade” to describe an electrical storm or high-grade ventricular arrhythmias secondary to pericardial effusion.
