Qrs Morphology

Verapamil-sensitive fascicular ventricular tachycardia (VT) is the most common form of idiopathic left VT. According to the QRS morphology and the successful ablation site, left fascicular VT can be classified into three subgroups: left posterior fascicular VT, whose QRS morphology shows right bundle branch block (RBBB) configuration and superior axis (common form); left anterior fascicular VT, whose QRS morphology shows RBBB configuration and right-axis deviation (uncommon form), and upper septal fascicular VT, whose QRS morphology shows narrow QRS configuration and normal or right-axis deviation (rare form). Posterior and anterior fascicular VT can be successfully ablated at the posterior or anterior mid-septum with a diastolic Purkinje potential during VT or at the VT exit site with a fused pre-systolic Purkinje potential. Upper septal fascicular VT can also be ablated at the site with diastolic Purkinje potential at the upper septum. Recognition of the heterogeneity of this VT and its unique characteristics should facilitate appropriate diagnosis and therapy.

Abstract Background Implantable cardiac defibrillators (ICD) are a popular and effective option in heart failure with left ventricular systolic dysfunction patients. Although frequently underdiagnosed, inadvertent malposition can lead to endocardial damage and thrombotic events. As ICD implants tend to increase in the following years, the recognition of their complications is critical. Case presentation The authors present a case of a 64-year-old woman with advanced heart failure and ICD malposition. This accidental discovery was denounced by the presence of a right bundle branch block pattern and later confirmed by echocardiography which showed the lead tip in contact with the mid segment of the left ventricular antero-lateral wall. As the patient hospitalisation was complicated with refractory ascites and cardiogenic shock, she underwent cardiac transplantation, with no recurrence of heart failure symptoms. Conclusions An electrocardiogram showing a right bundle branch block pattern during VVI pacing should arise the suspicion of inadvertent placement of a pacing/ICD lead. The many facets of echocardiography should be used for the diagnosis of this complication, as they were paramount in this case, as highlighted.

Congenitally corrected transposition of the great arteries (CCTGA) has a high incidence of dextrocardia and complete heart block. We describe a 34 year-old male with CCTGA, dextrocardia, and third degree atrioventricular block status-post dual chamber pacemaker that presented with acute heart failure syndrome. Cardiac CT Angiography confirmed CCTGA with situs solitus and dextrocardia. EKG with standard frontal leads showed a normal P wave axis and right-sided precordial leads showed a right bundle branch block pattern. With situs solitus there is a normal P wave axis on standard frontal leads. With nonsystemic ventricular pacing in CCTGA with dextrocardia left- and right-sided precordial leads show a left bundle branch block pattern and right bundle branch block pattern respectively. This case highlights electrocardiographic patterns seen with dextrocardia and morphologic reversal of ventricles.
