An 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 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 ...
متن کاملAn 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 کاملpersistent isolated right atrial standstill associated with left atrial tachycardia
introduction atrial standstill is a rare condition, characterized by absence of atrial electrical and mechanical activity evident in surface electrocardiography echocardiography, or fluoroscopy, which is associated with unresponsiveness of atria to maximal output electrical stimulation. this condition can be present with thromboembolic complication, low cardiac output, and sometimes palpitation...
متن کاملSustained Dissociated Irregular Tachycardia in Two Pulmonary Veins After Radiofrequency Ablation of Atrial Fibrillation.
A 64-year-old woman underwent radiofrequency ablation of atrial fibrillation. After pulmonary vein (PV) isolation, she converted into sinus rhythm. However, irregular PV tachycardia "trapped" in the right and left superior pulmonary vein (RSPV/LSPV) sustained. Fifteen minutes after RSPV isolation, the RSPV tachycardia terminated. However, sustained LSPV tachycardia was still present after one h...
