Pericardial Tamponade: Electrical Alternans
Report:Sinus tachycardia 111/min Small voltage Electrical alternans Comment:Alternate QRS complexes vary in size, in this case due to the heart swinging in the pericardial sac. There is no mechanical counterpart, but there may be alternation of the hea
Absolute Small Voltage
Report: Sinus rhythm Absolute small voltage Poor R wave progression Nonspecific ST/T changes Comment: The QRS amplitude is less than 0.5 mV (5 mm) in all the frontal plane leads and less than 1.0 mV in all the chest leads. The patient had been off st
True Alternans in Cardiac Tamponade
Report:Sinus tachycardia 126 - 132/min Electrical alternans Comment:By definition, there must be no change in rhythm or conduction for alternans to be diagnosed. In this case, the mechanism is the "swinging" of the heart, pendulum-like, within the peric
