An Irregular Wide Complex Tachycardia.
A 66-year-old woman with a history of hypertension and persistent atrial fibrillation was referred to the Arrhythmia Clinic. Before her visit, a routine 12-lead ECG was ordered (Figure 1). The patient was asymptomatic except for minor palpitations. Her medicine regimen included apixaban, flecainide 150 mg twice daily, lisinopril, loratadine, metoprolol, and simvastatin. What is the cardiac rhyt...
متن کاملAn irregular atrial tachycardia
There are clearly visible P-waves in most of the leads (Fig. 1). The P-waves are negative in leads DII, DIII and aVF. Hence, this is not a sinus rhythm. All the P-waves have the same morphology, constant PP interval at a rate of 210 beats per minute (bpm), with an isoelectric baseline between them. Therefore, the underlying rhythm is unifocal atrial tachycardia [1]. Lead DII shows 12P-waves, bu...
متن کاملWide-complex tachycardia.
To the Editor: The Images in Cardiovascular Medicine section of the August 29, 2000 issue of Circulation presented a case of wide-complex tachycardia (WCT) that reportedly required placement of a transesophageal lead to diagnose ventricular tachycardia (VT).1 Pharmacological trials of adenosine, diltiazem, lidocaine, and procainamide were noted to be unhelpful. In our view, the diagnosis of VT ...
متن کاملWide QRS Complex Tachycardia
A 71-year-old man with a history of previous myocardial infarction was referred to our hospital for recurrent symptoms of palpitation and syncope. During an episode of palpitations, a 12-lead ECG (Figure 1) was obtained in the emergency room. The ECG shows a wide-QRS complex tachycardia at a rate of 167 bpm. The P waves are positive in lead II (↑) before each QRS complex, and the PR interval is...
متن کاملAn irregular, narrow QRS complex tachycardia with ventriculoatrial block: what is the tachycardia mechanism?
A 57-year-old woman underwent an electrophysiology procedure because of a 19-year history of recurrent palpitations. Typical AV nodal reentrant tachycardia that had a cycle length of 460 msec was induced by ventricular pacing. Slow pathway ablation was attempted using a combined anatomical and electrogramguided approach. After an application of radiofrequency energy associated with junctional e...
