   en.wikipedia.org/wiki/Coronary_CT_calcium_scan

   A coronary CT calcium scan is a computed tomography (CT) scan of the heart for the assessment of severity of coronary artery disease. Specifically, it looks for calcium deposits in atherosclerotic plaques in the coronary arteries that can narrow arteries and increase the risk of heart attack. [1] These plaques are the cause of most heart ...

   In Stone Heart Syndrome, this delicate balance is disrupted. The excessive influx or release of calcium from intracellular stores overwhelms the cell's ability to remove it, leading to a sustained contraction state. [1] This prolonged contraction causes the heart muscle to become extremely rigid, resembling stone - hence the syndrome's name.

   When it's phosphorylated by PKA, levels of calcium stored in the sarcoplasmic reticulum are increased, allowing a higher rate of calcium being released at the next contraction. However, the increased rate of calcium sequestration also leads to an increase in lusitropy. Sensitizing troponin-C to the effects of calcium.

9. Long QT syndrome - Wikipedia

   en.wikipedia.org/wiki/Long_QT_syndrome

   Long QT syndrome (LQTS) is a condition affecting repolarization (relaxing) of the heart after a heartbeat, giving rise to an abnormally lengthy QT interval. [7] It results in an increased risk of an irregular heartbeat which can result in fainting, drowning, seizures, or sudden death. [1]
