A proposal of clinical ECG index “vagal score” for determining the mechanism of paroxysmal atrioventricular block

Paroxysmal atrioventricular block (P‐AVB) is a well‐known cause of syncope; however, its underlying mechanism is difficult to determine. This study aimed to evaluate a new ECG index, the “vagal score (VS),” to determine the mechanism of P‐AVB.

Long-term reliability of sweet-tip type screw-in leads

Active fixation leads have provided stable atrial and ventricular pacing; however, long‐term follow‐up data have not been satisfactory. The purpose of this study was to investigate the long‐term reliability of active fixation leads and their electrical characteristic stability.

Stability of intrinsic rhythm in pacemaker-dependent patients during pacemaker replacement: Can we predict the need for temporary pacing?

In pacemaker‐dependent patients, the risk of asystole must be managed during device replacement. This study aimed to examine whether we could predict the indication for temporary pacing (TP) during the generator replacement.

Watching National Team Matches in World Cup Soccer 2014 on Television was Associated with Increasing Frequency of Premature Ventricular Contractions

Objective: Psychological triggers, such as emotional stress, increase the incidence of acute cardiovascular events. The association between soccer championships and risk of cardiovascular events remains controversial. A World Cup Soccer (WCS) match involving a national team might be a strong enough trigger to induce cardiovascular events. However, there are no reports of a multicenter study that has investigated the relationship between watching WCS and cardiac arrhythmia. Methods: We assessed 25 patients who were evaluated for ischemic changes and/or arrhythmia using 24-h Holter electrocardiography in four cardiology divisions during WCS 2014. The patients were divided into two groups: the watching (W) group consisted of 7 patients who watched WCS on live television and the Non-Watching (NW) group consisted of 18 patients who did not watch WCS. Heart rates, arrhythmia, and ischemic changes were evaluated. Results: There were no differences in the clinical characteristics, heart rates, premature atrial contraction frequencies, and ischemic changes between the two groups. Although there were no differences in total Premature Ventricular Contractions (PVCs), the frequency of PVCs during matches (61 ± 101 vs. 7 ± 8, P = 0.03) and 1 hour before matches (15 ± 17 vs. 3 ± 5, P = 0.01) were significantly higher in the W group than in the NW group. No sustained ventricular tachycardia or fibrillation was observed. Conclusions: A significant association between watching WCS and frequency of PVCs was observed in patients with/or suspected of having cardiovascular disease.
