Paced Ventricular rhythm is controlled by a pacemaker, leading to a variable heart rate. It tends to be regular, but variability can occur based on pacemaker settings. P waves are typically absent or dissociated from QRS complexes. The PR interval is not applicable. QRS complexes vary in width and morphology depending on pacemaker and stimulation site. This rhythm is common in individuals with pacemakers, ensuring controlled and effective ventricular contractions.
Heart Rate: Varies
Rhythm: Regular
P wave: Typically absent or dissociated from QRS complexes
PR Interval: Not applicable or outside the normal range
QRS: Width and morphology depend on pacemaker location
Diagnosing paced ventricular rhythms involves a thorough assessment of the patient's medical history, focusing on the presence of a pacemaker. A careful review of the pacing mode and settings is crucial. Electrocardiogram (ECG) remains a key diagnostic tool, helping to identify paced beats and assess the overall rhythm. Holter monitoring may be employed for continuous monitoring, providing a comprehensive view of the pacing pattern and any associated arrhythmias.
Treatment for paced ventricular rhythms depends on the specific issues identified. In cases where the pacemaker is functioning appropriately, and there are no adverse symptoms, a conservative approach with regular follow-ups may be adopted. However, if there are concerns about pacing system malfunction, adjustments to the pacemaker settings or potential device replacement may be necessary.
