Abstract:
Background: Hypocalcemia is a famous serious electrolyte disorder characterized by calcium deficiency. It is recently associated with specific electrocardiographic changes such as both wavy triple and double electrocardiographic signs (Yasser signs). Method of study and patients: My study was an observational retrospective for 43 cases. The study was conducted in both Fraskour Central Hospital and Physician Outpatient Clinic. The author reported the 43-cases thorough nearly 24-months, started from December 3, 2018, and, ended on October 29, 2020. Wavy triple an electrocardiographic sign (Yasser Sign) of hypocalcemia was the target. Both manifested tetany or latent hypocalcemia are included. Parenteral or oral calcium preparation was supplied. Results: The Mean age was: 36.4 years, with female sex predominance (67.44%). The main presentations in the study were carpopedal spasm (55.81 %) vs. Parathesia and tingling (44.19%). Hyperventilation syndrome (60.47 %) and malnutrition (9.3%) are the most common risk factors. Manifested tetany was the commonest final diagnosis (55.81). The patterns of Movable phenomenon were: regressive (30.23%), weaning-off (20.93%), progressive (13.95%), changeable (13.95%), variable: 4.56%, reversed (4.56%), regressive characteristic (2.33%), unknown (2.33%), reversed with progression (2.33%) changeable with regression, (2.33%), and intermittent with regression (2.33%). Conclusions: Movable-weaning off an electrocardiographic phenomenon in hypocalcemia (changeable phenomenon or Yasser’s phenomenon of hypocalcemia) is defined according to the author's opinion in the study as a novel electrocardiographic phenomenon characterized by serial dynamic changes in present in all cases of either Wavy triple or double electrocardiographic signs (Yasser signs) of hypocalcemia. Movable-weaning off an electrocardiographic phenomenon is a guide for both Wavy triple or double electrocardiographic signs (Yasser signs) of hypocalcemia. Don’t be angry if the staring electrocardiography or the last one was normal.
