Tachycardia and bradycardia coexisting in the same pulmonary vein

Journal of Cardiovascular Electrophysiology

Abstract

During segmental isolation of the pulmonary veins (PVs) in a patient with paroxysmal atrial fibrillation, there was a PV bradycardia that was dissociated from the left atrium in a segment of the right superior PV, whereas the remaining segments showed passive activation of a PV fascicle during sinus rhythm. Rapid atrial pacing induced a PV tachycardia in the nonisolated fascicles, and the dissociated PV bradycardia persisted in a segment of the same PV. These observations indicate that PV fascicles are insulated from each other and that a dissociated PV rhythm does not necessarily indicate complete isolation of a PV.

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.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Bradyarrhythmias

Bradyarrhythmias are slow heart rates. Symptoms may include syncope, dizziness, fatigure, shortness of breath, and chest pains. Find the latest research on bradyarrhythmias here.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
