Morphology The assessment of the morphology of the ectopic QRS complex on the ECG helps to identify the anatomical origin of the VA (table 2). Idiopathic PVBs are characterised by the absence of an ...

The QRS complex detection technique for intelligent ECG monitor was presented. Firstly, the pretreatment of ECG data including the rejection of 50Hz power-line interference and the removal of baseline ...

The QRS complex is the most significant segment in the Electrocardiography (ECG) signal. By detecting its position, we can learn the physiological informations of the subjects, e.g. heart rate. In ...

Not surprisingly, surface ECG has been extensively studied in this role with features such as late potentials on signal averaged ECG, QRS duration and QT prolongation studied with no reliable ...

Hollywood has shaped how many people imagine a heart attack—someone clutching their chest and collapsing dramatically. But ...

Cardiovascular diseases are a leading health concern in Hong Kong, prompting many to undergo regular heart check-ups for ...

Background Biventricular pacing (CRT) shows clear benefits in heart failure with wide QRS, but results in patients with narrow QRS have been conflicting. In this meta-analysis we tested the hypothesis ...
