Sinus rhythmVentricular tachycardiaVentricular tachycardia (VT) substrate in left ventricular (LV) nonischemic cardiomyopathy (NICM) consists of fibrosis with surviving myocardium. The purpose of this study was to determine whether, in patients with LV NICM and sustained VT, reduced QRS amplitude and ...
In normal sinus rhythm, what does the P-wave, the PR interval, QRS complex, and QT interval reflect? ECG: An ECG, or electrocardiogram, is an electrical readout of the heart which measures the electrical output of all heart chambers during cardiac cycles. ...
Four patients are described who had long conduction times and decremental conduction through right anterior accessory connections. None had Wolff-Parkinson-White syndrome on their ECG. Each had recurrent sustained wide QRS tachycardia due to antegrade conduction through the accessory connection. Three patie...
A 74-year-old man with coronary artery disease and bifascicular block suffered from recurrent tachycardia. Although the similarity of QRS morphology in tachycardia and sinus rhythm suggested a supravenlricular origin, His bundle electrocardiography and programmed stimulation showed a ventricular origin. ...
