Pacing Clin Electrophysiol. 2008;31(2):229-231. A 52-year-old man was admitted in our institution with cranial traumatism due to a syn-copal episode that occurred while he was walking. Several weeks ...
Fragmented QRS complexes (fQRS) are defined by additional notches or slurs within the standard QRS waveform on a 12-lead electrocardiogram. These irregularities arise from heterogeneous ventricular ...
THE electrocardiographic picture of prolonged QRS-complex duration with short PR interval was the subject of isolated reports 1,2 until Wolff, Parkinson and White 3 described the clinical syndrome of ...
The mechanism of the benefits achieved with the therapy has been attributed to resynchronization of the dyssynchronous segments resulting from bundle branch block, especially left bundle branch block ...
Dr. Nino Mihatov: A 52-year-old woman was evaluated for a new wide-complex tachycardia that developed while she was hospitalized for the management of seizures. Five days before the development of ...
The QRS complex consists of the Q wave, the R wave and the S wave. The QRS complex comes after the P wave when the SA nodal action potential travels through the AV node to the ventricles to cause ...
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 three irregularly irregular rhythms are atrial fibrillation, atrial flutter with variable conduction and multifocal atrial tachycardia (similar to wandering atrial pacemaker). Atrioventricular (AV ...
