Nicole J van Steijn,Auke T Bergeman,Christian van der Werf et al.
Nicole J van Steijn et al.
Introduction: Handheld mobile ECG (mECG) devices offer potential for remote QTc surveillance in congenital long QT syndrome (cLQTS), but validation against standard 12‑lead ECGs is limited. ...
A child with a large ostium secundum atrial septal defect, pulmonary hypertension, and the characteristic Crochetage electro-vectorcardiographic pattern [0.03%]
巨大的卵圆孔型房间隔缺损、肺动脉高压和典型Crochetage心电图模式儿一例
Andrés Ricardo Pérez-Riera,Raimundo Barbosa-Barros,Maurício da Silva Rocha et al.
Andrés Ricardo Pérez-Riera et al.
The presence of a large ostium secundum atrial septal defect (OS-ASD) results in right atrial and right ventricular volume overload followed by pulmonary hypertension. In this context, a Crochetage electrocardiographic pattern can be observ...
Prognostic value of ECG T/R ratio and clinical predictors in septic shock [0.03%]

Teemu Pukkila,Topi Niemi,Esa Räsänen
Teemu Pukkila
Chronic heart failure (CHF) is a condition affecting millions worldwide, characterized by the heart's reduced ability to pump blood efficiently. Conventional diagnostics, such as imaging and ECG assessments, can be time-consuming and expens...
Accidental reactivation of a retained pacemaker leading to competitive ventricular pacing between two pacemakers: A case report [0.03%]
起搏器意外再激活导致两植入式心脏起搏器竞争控制心室搏动的临床病例报告
Xiaomao Wu,Zelin Li,Lulu Xu et al.
Xiaomao Wu et al.
Herein, we report a rare clinical case of competitive ventricular pacing caused by the accidental reactivation of a retained pacemaker two years after device replacement. Initially, two years following the implantation of the new pacemaker,...
