AACN Pediatric Clinical Nurse Specialists - Additional Info Sample Questions

A 12 lead ECG shows a P wave following a wide QRS wave. What type of rhythm is this?

Correct Answer:
ventricular rhythm.
in analyzing an electrocardiogram (ecg), the relationship between the p wave and the qrs complex is crucial for determining the type of cardiac rhythm. a 12-lead ecg showing a p wave following a wide qrs complex indicates a ventricular rhythm. this is a specific type of cardiac arrhythmia that originates from the ventricles rather than the atria or the sinoatrial (sa) node, which is the usual pacemaker of the heart.

in a normal sinus rhythm, the sa node initiates the electrical impulse, causing depolarization of the atria and the production of a p wave, which is followed by the qrs complex representing ventricular depolarization. the p wave precedes the qrs complex, and the qrs complex is typically narrow, reflecting the rapid conduction through the ventricular conduction system.

in contrast, a ventricular rhythm, such as ventricular tachycardia, arises from an ectopic focus within the ventricles. this results in a wide and abnormal qrs complex because the electrical impulse does not follow the usual rapid conduction pathway through the his-purkinje system but spreads slowly through the ventricular myocardium. the p wave in ventricular rhythms may follow the qrs complex or may be absent or buried within the qrs complex, reflecting the independent and unsynchronized activity between the atria and the ventricles.

the presence of a p wave following a wide qrs complex suggests that the atria are not contributing to the initiation of the ventricular activity but are depolarizing independently from the ventricles. this can be indicative of a complete heart block where the normal conduction pathway between the atria and ventricles (via the atrioventricular node) is disrupted, and the ventricles adopt an independent pacemaker, often resulting in a slower and more unstable rhythm.

identifying a ventricular rhythm on an ecg is crucial because these types of arrhythmias can be life-threatening, often requiring immediate medical attention and intervention to restore normal rhythm and prevent complications such as cardiac arrest or ventricular fibrillation. treatment options might include medications, electrical cardioversion, or implantation of devices such as pacemakers or defibrillators depending on the underlying cause and the stability of the patient.
