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 کاملIrregular Narrow Complex Tachycardia in a 29-Year-Old Woman.
A 29-year-old woman without known medical illness was evaluated for incessant palpitations. She presented to an emergency department multiple times, where various diagnoses were made, including junctional tachycardia, atrial tachycardia, and atrial fibrillation. Therapy with propafenone, metoprolol, and rivaroxaban was initiated, but her symptoms continued. Echocardiography did not show evidenc...
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 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...
متن کاملRegular supraventricular tachycardia with irregular atrial activations.
A 19-year-old woman developed a recurrent supraventricular tachycardia (SVT) 3 months after catheter ablation of a typical slow-fast type atrioventricular nodal re-entrant tachycardia (AVNRT). During the procedure, the slow pathway was mapped and ablated anterior to the bottom of the coronary sinus (CS) ostium. She was referred to our institute and underwent electrophysiological testing a year ...
