Case in brief
A 70-year-old male presented with cardiogenic shock and elevated D-dimer levels after thrombolysis, initially raising suspicion for massive pulmonary embolism. However, dynamic ECG monitoring revealed significant pseudo-P pulmonale, which was not correlated with D-dimer levels. Further assessment through postural changes and extubation indicated that this finding was due to severe backward pressure from acute left ventricular failure, compounded by high PEEP.
Diagnostic / clinical pearl
Dynamic ECG monitoring can reveal complex cardiopulmonary interactions, particularly in cases of cardiogenic shock, helping to differentiate between conditions that may mimic each other.
Why it matters
Understanding the electrophysiological manifestations of severe left ventricular failure can aid in accurate diagnosis and management in critical care settings.
