Which of the following is the most common type of sustained arrhythmia in clinical practice?
Correct!
Wrong!
Atrial fibrillation is the most common sustained arrhythmia, characterized by rapid and irregular beating of the atria.
Which arrhythmia is characterized by a "sawtooth" pattern on an electrocardiogram (ECG)?
Correct!
Wrong!
Atrial flutter is identified by a “sawtooth” pattern on the ECG, caused by rapid, regular atrial contractions.
What is the typical heart rate range associated with sinus tachycardia?
Correct!
Wrong!
Sinus tachycardia is characterized by a heart rate typically between 100 and 150 beats per minute, usually in response to factors like stress, fever, or exercise.
Which of the following is the most appropriate initial treatment for a hemodynamically unstable patient with ventricular tachycardia?
Correct!
Wrong!
Synchronized cardioversion is the recommended treatment for patients with hemodynamically unstable ventricular tachycardia, as it restores normal rhythm quickly.
Which arrhythmia is typically associated with a prolonged QT interval and can lead to Torsades de Pointes?
Correct!
Wrong!
Long QT syndrome is associated with a prolonged QT interval on the ECG, increasing the risk of developing Torsades de Pointes, a potentially life-threatening arrhythmia.
