Crytotetany --> latent tetany

a rather vague disorder recognised more in Europe than in the U.S. Consisting of a number of non-specific complaints, including generalised weakness, hand and foot cramping, distal paresthesia, anxiety, and depression. Some think it is a normocalcaemic tetany; others consider it chronic hyperventilation syndrome. Typically with certain provoking procedures (e.g., limb ischemia, hyperventilation) in which case, obvious tetany develops.
