Abstract
Objective To investigate the observation and nursing for patients with atria] fibrillation (AF)after left atrial linear ablation surrounding ipeilateral pulmonary veins (PVs). Methods Thirty patients with persistent AF underwent left atrial linear ablation surrounding ipsilateral PVs guided by CARTO electroanatomic mapping system and double Lasso catheters technique. The end point of ablation was defined as absence of all PV spikes after isolation and bidirectional conduction block between left atrial and PVs. Results After a median of (245±65)days of follow-up, twenty-one patients were free of AF. Eight patients subjected recurrent atrial tachyarrhymias, including 5 typical AFL, 2 atrial taehycardia and 1 paroxysmal AF. Two patients with persistent AF remaining PV spikes in left superior PV failed to be translated to sinus rhythm. Nine patients underwent repeated ablation and 8 of them were free of atrial taehyarrhythmia after (192±92) days follow-up. Total success rate after two procedures was 92.8%. Conclusions Nurses should perform effective care according to the symptom of patients before, during and after ablation procedure and relieve the patients from pain.
