Displacement of the target ablation site and ventricles during premature ventricular contractions: relevance for radiofrequency catheter ablation

Abstract

During premature ventricular contractions (PVCs), a spatial displacement of the ventricles and the target ablation site with respect to the sinus rhythm (SR) position is observed during mapping and ablation. To analyze this displacement and its relevance for image integration and PVC ablation. The electroanatomical activation maps (EAMs) of 55 consecutive patients who underwent PVC ablation were analyzed. Spatial displacement between each point position during PVC and SR was obtained. A total of 6923 points from 71 EAMs were analyzed. Overall, the median distance between the point position during SR and PVC for all the points was 9.42 mm (interquartile range [IQR]: 6.19-12.85). The EAM points from the right ventricle showed more displacement than did those from the left ventricle: 10.35 mm (IQR: 7.16-13.95) vs 7.62 mm (IQR: 5.20-10.81); P <.001. The ventricular end-diastolic volume of the EAM during SR was greater than that during PVC (median difference: 9.75 [IQR: 0.37-19.67] mL; P = .002). A shorter coupling interval of the PVC was associated with greater spatial displacement (r = -.521; P <.001), higher end-diastolic volume reduction with respect to the SR beat (r = -.718; P = .001), and worse image integration (mean point-t...Continue Reading

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
