ISCE is an association that organises annual scientific meetings and interactive sessions with regulatory bodies. These sessions are of particular relevance to the electrocardiogram. The paucity of information regarding the history of ISCE ...
Evaluation of new vectorcardiography algorithms for identifying left ventricular hypertrophy and impaired systolic function [0.03%]
新算法在向量心电图诊断左室肥厚和收缩功能不全中的价值评估

Janek Salatzki et al.
Background: Timely diagnosis of impaired systolic function and left ventricular hypertrophy (LVH) remains a clinical challenge. Routine electrocardiography provides limited diagnostic accuracy for detecting early or subtl...
Activation dispersion index as a novel ECG marker for assessing ventricular electrical synchrony: Left bundle branch area pacing versus right ventricular apical pacing in post-TAVI patients with high-grade atrioventricular block [0.03%]
激活分散指数作为新的心电图标志用于评估经导管主动脉瓣置换术后高度房室传导阻滞患者左束支区域起搏与右心室尖端起搏的 ventricular 电活动同步性：一项初步研究

Gültekin Günhan Demir et al.
Background: Permanent pacemaker implantation is required in approximately 10-25% of patients following transcatheter aortic valve implantation (TAVI) due to complete atrioventricular (AV) block. Conventional right ventric...
Opposite calcium disorders, similar electrical risk: Reversible cardiomyopathy due to hypocalcemia and Brugada syndrome unmasked by hypercalcemia [0.03%]
相反的钙离子紊乱，相似的心电风险：高钙血症诱发的可逆性低钙血性心肌病和布鲁加达综合征

Background: Criss-cross is a rare congenital heart disease, of which the electrocardiographic characteristics are not precisely known for early diagnosis. ...
Comparison of measured and synthesized right-sided precordial electrocardiograms in patients with right ventricular infarction [0.03%]
Toshiki Setoguchi,Naoya Matsumoto,Yuro Matsunaga et al.
Toshiki Setoguchi et al.
Background: Right-sided chest precordial electrocardiogram (ECG) leads (V3R-V5R) are critical for diagnosing right ventricular (RV) infarction complicating acute inferior wall myocardial infarction. However, obtaining the...

We report a 78-year-old asymptomatic woman with no cardiac history and unremarkable cardiac evaluation, referred for a pre-surgical ECG showing diffuse T-wave inversion. Following ventriculoperitoneal shunting for chronic normal-pressure hy...
Post procedural changes in frontal QRS-T angle predict electrical disturbances after self-expandable transcatheter aortic valve implantation [0.03%]
术后房室间隔角度的变化可预测自膨胀经导管主动脉瓣植入后的电紊乱事件
Enes Alıç,Mehdi Onaç,Mohamed Niang et al.
Enes Alıç et al.
Background: Electrical disturbances are common complications after transcatheter aortic valve implantation (TAVI), particularly with self-expandable valves. Improved noninvasive markers are needed to identify patients at ...
