What sinus tachycardia usually develop? {Ans: The body needs increased cardiac output.}What are the characteristics of atrial flutter? {Ans: - Atrial rate 300 /min or higher - Venticular rate often slower - Can occur in congenital heart disease - A narrow-complex tachyarrhythmia}What is the appropriate initial cardioversion dose? {Ans: 0.5 - 1 J/kg}Define bradycardia. {Ans: A heart rate that is: - slow for normal range - activity - clinical condition}What is considered part of post-cardiac arrest care? {Ans: Ensure adequate analgesia and sedation. Correct acid-base and electrolyte imbalances. Provide adequate oxygenation and ventilation.}What is a characteristic feature of SVT? {Ans: Abrupt onset or termination of the tachycardia, with minimal or no variation in heart rate with activity. CHF may be present.}How is tachycardia defined? {Ans: A heart rate that is fast for the child's age.}What ECG characteristics are consistent with sinus tachycardia? {Ans: Beat-to-beat variability with changes in activity.}What are the causes of primary bradycardia? {Ans: Congenital or acquired heart conditions.}What is the priority in initially managing arrhythmias? {Ans: The initial management of both stable and unstable arrhythmias are identical to the treatment for any critically-ill child.
