Symptoms of hypocalcemia include paresthesia, muscle spasms, cramps, tetany, circumoral numbness, and seizures. Hypocalcemia can also present with laryngospasm, neuromuscular irritability, cognitive impairment, prolonged QT intervals, electrocardiographic signs of myocardial infarction, or heart failure.
Prolonged QRS duration indicates abnormal conduction through the His-Purkinje system leading to longer period of depolarization. QT interval varies by heart rate, therefore, corrected QT interval (QTc) is used instead. A normal QTc should be less than 0.42 sec in men and less than 0.45 sec in women.he QRS axis in this ECG is 150 degrees: Heart Rhythm. A normal heart rhythm is when the origin of the impulse is from the sinus node (sinus rhythm) with normal AV conduction. Therefore, a normal heart rhythm is when the P wave axis is normal + Normal AV conduction (PR interval) + Normal heart rate for age.
