Pulseless electrical activity

Now, it's important to understand that when you've made the diagnosis of an infiltrated cardiomyopathy with restrictive physiology, that we have a good understanding of how this has major implications for hemodynamics, how they present with heart failure, and their risk for dangerous cardiac arrhythmias.

As we learned in this case, unfortunately, this patient suffered a PEA arrest And I think it further highlights how humbling this disease process can be, where both patients can present with life-threatening arrhythmias, PEA arrest, conduction system abnormalities, heart blocks, and also ventricular tachycardia, which all can be life-threatening.

Usually the most common

arrhythmia that's associated with infiltrated cardiomyopathies and amyloidosis is atrial fibrillation.
