Response by Zhao et al to Letter Regarding Article, "Tachycardia-Induced Cardiomyopathy in a 43-Year-Old Man".
A 43-year-old man with a 5-year history of palpitation and dyspnea was referred to our hospital for further evaluation and management of persistent tachycardia. Before his referral, pharmacological therapy with metoprolol and digoxin failed to alleviate his symptoms. He reported no other significant medical history. On presentation, he had an irregular heart rate of 109 beats/min. A12-lead ECG ...
متن کاملLetter by Denham et al Regarding Article, "Familial Occurrence of Atrioventricular Nodal Reentrant Tachycardia".
To the Editor: Michowitz et al present an interesting study on the prevalence of familial atrioventricular nodal reentrant tachycardia (AVNRT). They report a prevalence of 127 out of 10 000 of familial AVNRT with a likely autosomal dominant pattern of inheritance (with incomplete penetrance). A potentially important question is whether all the observed cases represent “pure” familial AVNRT or w...
متن کاملLetter by Namboodiri Regarding Article, "A Narrow QRS Complex Tachycardia With Apparently Concentric Retrograde Atrial Activation Sequence" - Alternative Mechanisms
Read with interest the article by Arias et al on a case of orthodromic atrioventricular reentry (ORT) mediated through the left free wall (LFW) accessory pathway(AP) with an apparently concentric atrial activation sequence [1]. Based on the observation that the atrial signals during the tachycardia were earlier in the His bundle (HB, anterosuperior septum) compared to the proximal coronary sinu...
متن کاملLetter by Mahajan Regarding Article, "A Narrow QRS Complex Tachycardia With Apparently Concentric Retrograde Atrial Activation Sequence"
Arias et al in the article 'A Narrow QRS Complex Tachycardia with an Apparently Concentric Retrograde Atrial Activation Sequence' describe a case with spontaneous intra atrial block along the mitral isthmus to explain the change in atrial activation [1]. This phenomenon has been described during radiofrequency ablation while ablating along the lateral mitral annulus for a left free wall pathway...
متن کاملElectrophysiology: Ventricular tachycardia: diagnosis of broad QRS complex tachycardia.
having a broad QRS complex, it is important to be able to diVerentiate between a supraventricular and a ventricular tachycardia. Medication given for the treatment of a supraventricular tachycardia (SVT) may be harmful to a patient with a ventricular tachycardia (VT). 2 A reasonable haemodynamic condition during a tachycardia may erroneously lead to the wrong diagnosis of SVT. Familiarity with ...
