A heart that should have burst.
The heart is rebuilt to survive outputs that would tear an ordinary one. The bloodwork still looks catastrophic.
The cardiac module

Myocardium in section, hypertrophied, membranes rewritten for a rate and pressure that should fibrillate a human heart. A heart that should have burst. The adaptation is the drawing.
The asks the heart for outputs that would rupture an unprepared myocardium. 's answer is a cardiac module: increased intermyofibrillar mitochondrial density, retuned calcium handling, and the MMP2 proteoglycan modification that lets chambers fill further without tearing. Stroke volume climbs. The organ survives a night at a duty cycle that would be a medical emergency in any other chest.
Dawn does not forgive all of it. Creatine kinase leaks. Troponin flickers. The recovery window of hours one through seventy-two is where the clinical misdiagnoses live: viral myocarditis, panic disorder, unexplained rhabdomyolysis. The heart held. The bloodwork looks like a disaster.
