Aim of the study: Aim of the study is a clearing of the presence of Wavy triple an electrocardiographic sign (Yasser sign) in hypocalcemia and its diagnostic and therapeutic value.
Background: Hypocalcemia is a well-known serious electrolyte disturbance characterized by calcium deficiency. It is associated with non-specific electrocardiographic changes.
Method of study and patients: My case study was an observational retrospective 37-case report series. The study was conducted in both Fraskour Central Hospital and (in both the Emergency Department, Internal Ward, and Intensive Care Unit) and Physician Outpatient Clinic. The author reported the 37-cases through nearly 15-months, started from March 12, 2018, and, ended on Jun 8, 2019. Tetany or latent hypocalcemia are included. Parenteral or oral calcium preparation was supplied.
Results: The Mean age was: 38.4 years, with female sex predominance (72.97%). Hyperventilation syndrome (45.95%) and malnutrition (24.32%) are the most common risk factors. Carpopedal spasm was the main complaint (89.19 %). Manifested tetany was the commonest final diagnosis (89.19 %). The Wavy triple sign is a positive and triple sign in 97.3% (36 cases) but it is only double in 2.7% (1 case). The Mean number of affected electrocardiographic leads: 4.13, Max.:10, and Min.:1). The number of affected ECG leads correlate with the level of ionized calcium in the investigated group. Electrocardiographic recovery after calcium administration in the first group was completed in 97.3% vs. partial in 2.7%.
Conclusions: The Wavy triple an electrocardiographic sign (Yasser sign) is a new diagnostic sign seen in 97.3% (36 cases) of hypocalcemia. Dramatic improvement of both clinical manifestation and the new electrocardiographic sign simultaneously after calcium replacement had happened.
