Current Algorithms for the Diagnosis of wide QRS Complex Tachycardias
The differential diagnosis of a regular, monomorphic wide QRS complex tachycardia (WCT) mechanism represents a great diagnostic dilemma commonly encountered by the practicing physician, which has important implications for acute arrhythmia management, further work-up, prognosis and chronic management as well. This comprehensive review discusses the causes and differential diagnosis of WCT, and ...
متن کاملRegular narrow QRS and regular wide QRS tachycardias in a woman with mitral regurgitation of uncertain etiology.
A 64-year-old woman had been experiencing short episodes of rapid regular heart beating for nearly a year. The bouts became frequent and lengthy, resulting in a hospital admission a month earlier when intravenously administered adenosine terminated an episode. She was discharged on diltiazem, but the bouts of tachycardia continued and were accompanied by light-headedness and sometimes nausea. W...
متن کاملClinical significance of wide QRS complexes at the termination of paroxysmal supraventricular tachycardias.
BACKGROUND A wide QRS complex is not a rare electrocardiographic phenomenon at the termination of paroxysmal supraventricular tachycardia (PSVT), but no plausible underlying mechanism has yet been proposed. The purpose of the present study was to elucidate the frequency and the underlying mechanism of the wide QRS complexes at the termination of PSVT. METHODS We retrospectively reviewed 305 e...
متن کاملR-wave peak time at DII: a new criterion for differentiating between wide complex QRS tachycardias.
BACKGROUND Differential diagnosis of wide QRS complex tachycardias using the 12-lead ECG may be difficult in many clinical settings. OBJECTIVE The purpose of this study was to determine the value of ECG lead II, specifically, the duration at its beginning, defined as R-wave peak time (RWPT), in differentiating ventricular tachycardia (VT) from supraventricular tachycardia (SVT) in patients wi...
متن کاملDifferential diagnosis of wide QRS tachycardias: comparison of two electrocardiographic algorithms.
AIMS This study's aim is to compare the ability of two ECG criteria to differentiate ventricular (VT) from supraventricular tachycardia (SVT): Brugada et al. [horizontal plane (HP) leads] and Vereckei et al. [frontal plane (FP), specifically aVR lead], having electrophysiological study (EPS) as gold standard. After comparing, suggestions for better diagnosis of wide QRS-complex tachycardia (WCT...
