Ventricular Fibrillation and Cardiac Dysrhythmias Quiz

Ventricular fibrillation is an irregular heart rhythm originating in the ventricles.

Electrical shock is a common cause of ventricular fibrillation.

Atrial fibrillation is the term for a rapid, irregular heart rate originating from the atria.

The immediate management step for ventricular fibrillation in a healthcare setting is initiating chest compressions and defibrillation.

Cardiopulmonary resuscitation (CPR) is the treatment of choice for ventricular fibrillation.

Ventricular fibrillation is characterized by the absence of P waves on an electrocardiogram (ECG).

A potential complication of untreated ventricular fibrillation is sudden cardiac death.

Amiodarone is commonly used to treat ventricular fibrillation.

Coronary artery disease is a risk factor for developing ventricular fibrillation.

The main difference between ventricular fibrillation and ventricular tachycardia is that ventricular fibrillation is slow and irregular, while ventricular tachycardia is fast and regular.

Myocardial infarction is most likely to precede the development of ventricular fibrillation.

Sinus bradycardia is the term for an abnormal rhythm originating in the sinus node, resulting in heartbeats slower than normal.

Long QT syndrome may increase the risk of ventricular fibrillation.

A characteristic of ventricular fibrillation on a cardiac monitor is the absence of QRS complexes.

The most common initial rhythm observed during sudden cardiac arrest is asystole.

The term for a brief cessation of cardiac activity resulting from myocardial ischemia is cardiac arrest.

A potential complication of defibrillation is heart block.

The term for a condition characterized by chaotic, irregular electrical activity in the atria is atrial fibrillation.

A possible consequence of prolonged ventricular fibrillation is brain damage.

The primary cause of ventricular fibrillation in patients with acute myocardial infarction is myocardial ischemia.

Chest pain can be a symptom of ventricular fibrillation.

The purpose of defibrillation in the management of ventricular fibrillation is to restore normal heart rhythm.

The approximate survival rate for patients experiencing ventricular fibrillation outside of a hospital setting without immediate intervention is less than 5%.
