The initial part of the ECG shows a regular narrow complex tachycardia at a rate of 160 beats/min. The QRS complex duration is normal (0.08 sec) and there is normal morphology and normal axis between ...
This is a narrow complex tachycardia with a rate of 124 beats/min. The QRS morphology and axis are normal. The QTc is prolonged, at 529 ms (normal, 390-450 ms for men). The underlying P waves appear ...
This is a narrow QRS complex tachycardia with a very fast heart rate (about 250 beats per minute). It is quite difficult to indentify any P wave activity to determine the exact etiology. Most commonly ...
There is clearly a tachycardia with narrow QRS complexes indicating a supraventricular rhythm. The clues to the aetiology are the heart rate of almost exactly 150 / min and the saw tooth waves seen ...
The diagnosis is nonsustained atrial tachycardia and left ventricular hypertrophy (LVH) with associated ST-T wave changes. There is a regular narrow complex tachycardia at a rate of 240 beats/min. At ...
EurekAlert!: A new image processing strategy for cardiac magnetic resonance imaging identifies culprit areas underlying complex tachycardias
A new image processing strategy for cardiac magnetic resonance imaging identifies culprit areas underlying complex tachycardias
Narrow-complex tachyarrhythmias are rapid heart rhythms originating in the upper heart chambers, characterized by a QRS duration of less than 120 milliseconds on an EKG. These arrhythmias can be ...
The correct diagnosis is ventricular tachycardia (Figure 2). The rhythm is regular with a rate of 130 beats/min. The QRS complexes are wide (0.16 sec) without the morphology of a typical right or left ...
