Question

Quizplus · Accepted Answer

Both PJC and junctional tachycardia can have hidden P waves, meaning that the P wave may not be visible on an ECG tracing or may be hidden within the QRS complex. However, they are not similar in terms of regularity (PJC can be irregular while junctional tachycardia is regular) and heart rates (PJC is usually faster than junctional tachycardia). Additionally, electrical shock to the heart is not typically required for either condition.
