Correct Answer is A

Explanation

A. The P wave on an ECG represents atrial depolarization, which occurs as the electrical impulse originates in the sinoatrial (SA) node and spreads through the atria, initiating atrial contraction.
B. Atrial repolarization typically occurs during the QRS complex and is not represented by the P wave. Atrial repolarization is masked by the larger QRS complex.
C. Ventricular depolarization is represented by the QRS complex on an ECG, as the electrical impulse spreads through the ventricles, leading to ventricular contraction.
D. Ventricular repolarization typically occurs during the T wave and is not represented by the P wave. Ventricular repolarization involves the recovery of ventricular muscle cells after contraction.

A. Atrial fibrillation B. Asystole C. Ventricular fibrillation D. Atrial flutter

Correct Answer is B

Explanation

A. Atrial fibrillation is characterized by rapid, irregular electrical impulses originating from the atria, resulting in a quivering or fibrillating motion of the atria rather than a coordinated contraction.
B. Asystole is the absence of any electrical activity on the cardiac monitor, resulting in a flat line. It indicates the absence of ventricular contraction and is considered a medical emergency requiring immediate intervention (CPR and advanced cardiac life support).
C. Ventricular fibrillation is characterized by chaotic, disorganized electrical activity in the ventricles, resulting in ineffective quivering of the ventricles and loss of cardiac output.
D. Atrial flutter is characterized by rapid but regular electrical impulses originating from the atria, resulting in a sawtooth pattern on the ECG tracing.
