Background: Atrial tachyarrhythmias (ATAs) are reportedly associated with ventricular arrhythmias (VAs). However, little is known about the association between ATA duration and the risk of VA. We investigated the relationship between ATA duration and subsequent VA in patients with a cardiac resynchronization therapy defibrillator (CRT-D).Methods and Results: We investigated associations between the longest ATA duration during the first year after cardiac resynchronization therapy (CRT) implantation and VA and VA relevant to ATA (VAATA) in 160 CRT-D patients. ATAs occurred in 63 patients in the first year. During a median follow-up of 925 days from 1 year after CRT implantation, 40 patients experienced 483 VAs. Kaplan-Meier analysis showed a significantly higher risk of VA in patients with than without ATA in the first year (log rank P=0.0057). Hazard ratios (HR) of VA (HR 2.36, 2.10, and 3.04 for ATA >30s, >6 min and >24 h, respectively) and only VAATA (HR 4.50, 5.59, and 11.79 for ATA >30s, >6 min and >24 h, respectively) increased according to the duration of ATA. In multivariate analysis, ATA >24 h was an independent predictor of subsequent VA (HR 2.42; P=0.02).Conclusions: Patients with ATA >24 h in the first year after CRT had a higher risk of subsequent VA and VAATA. The risk of VA, including VAATA, increased with the longest ATA duration.

Background: Spontaneous type 1 electrocardiogram (ECG) in the right precordial lead is a dominant predictor of ventricular fibrillation (VF) in Brugada syndrome (BrS). In some BrS patients with VF, however, spontaneous type 1 ECG is undetectable, even in repeated ECG and immediately after VF. This study investigated differences between BrS patients with spontaneous or drug-induced type 1 ECG. Methods and Results: We evaluated 15 BrS patients with drug-induced (D-BrS) and 29 with spontaneous type 1 ECG (SP-BrS). All patients had had a previous VF episode. In each D-BrS patient, ECG was recorded more than 15 times (mean, 46±34) during 7.2±5.1 years of follow-up. Age and family history were comparable between groups. Inferolateral early repolarization (ER) was observed in 13 D-BrS (87%) at least once but in only 3 SP-BrS (10%, P<0.01). Immediately after VF, inferolateral ER was accentuated in 9 of 10 D-BrS, while type 1 ECG was accentuated in 12 of 16 SP-BrS. Fragmented QRS in the right precordial lead and aVR sign were absent in D-BrS but present in 20 (69%, P<0.01) and 11 (38%, P<0.01) SP-BrS, respectively. There was no prognostic difference between groups. Conclusions: Although having similar clinical profiles, there are obvious ECG differences between VF-positive BrS patients with spontaneous or drug-induced type 1 ECG. The inferolateral lead rather than the right precordial lead on ECG may be particularly crucial in some BrS patients.

The efficacy of direct current (DC) cardioversion before catheter ablation (CA) for persistent atrial fibrillation (PerAF) patients remains controversial. We hypothesized that maintenance of sinus rhythm (SR) by pre-ablation DC cardioversion may predict the outcome of CA in patients with PerAF. A total of 383 PerAF patients with no or mild symptoms (EHRA I/II) who had undergone DC cardioversion before CA (301 males, 65 ± 10 years old, mean atrial fibrillation (AF) duration: 25 ± 47 months) were retrospectively enrolled. Whether or not SR was maintained at least 24 hour after DC cardioversion, patients were divided into two groups, namely, the DC-SR group and DC-AF group, and then all were followed until AF recurrence after CA. After DC cardioversion, 281 (73%) patients were categorized into the DC-SR group, and 102 (27%) were categorized into the DC-AF group. A total of 195 patients underwent CA at an average of 83 (54-145) days after DC cardioversion, including 161 (83%) in the DC-SR group and 34 (17%) in the DC-AF group. During follow-up (median: 15 [10-25] months), the number of patients who were free from AF was significantly higher in the DC-SR group compared with the DC-AF group (61.5% versus 38.3%, P < 0.0001). Multivariate analysis revealed that the DC-SR group (hazard ratio [HR]: 0.45, 95% confidence interval [CI]: 0.21-0.99, P = 0.047) and age at first AF diagnosis (HR: 0.95, 95% CI: 0.91-1.00, P = 0.039) were the independent predictors for being AF-free after CA. In conclusion, the 24-hour rhythm outcome of pre-ablation DC cardioversion and age at first AF diagnosis may predict the recurrence of AF after CA in patients with PerAF.
