The 12 Lead ECG During Ventricular Tachycardia: Still an Important Tool for Ventricular Tachycardia Localization in Structural Heart Disease

The use of the 12-lead ECG recorded during ventricular tachycardia (VT) to regionalize its origin was first described by Josephson and colleagues in 1981 (1). The paper had 11 figures, unheard of by current publication standards, each showing one to five 12-lead ECG patterns during VT corresponding to a region of origin on the cardiac silhouette. Specific, but relatively simple rules based on the 12-lead ECG pattern were described. Basal left ventricular (LV) VTs have large R-waves across most precordial leads while apical VTs have no or poor R-wave progression or early regression.

Conclusion: Video-assisted CSD should be considered as a treatment option for patients with potentially dangerous arrhythmias that do not respond to conventional treatment, especially in recurrent ventricular tachycardia. PMID: 31588139 [PubMed - in process]

ConclusionsWnt signalling inhibits Na+ channel by direct and indirect (via Tbx3) suppression of Scn5a transcription. Strategies to block TCF4 binding to Tbx3 and Scn5a promoters would represent novel strategies for cardiac-specific inhibition of Wnt pathway to rescue INa and prevent sudden cardiac deaths.

The demonstrated effectiveness of implantable cardioverter-defibrillators (ICDs) for primary and secondary preventions of sudden cardiac death has resulted in an increasing number of patients presenting with recurrent, appropriate ICD shocks for ventricular tachycardia VT.(1) In a selected group of VT patients such as those included in the study by Bradfield and colleagues (2) in this issue of Heart Rhythm, autonomic modulation is considered as adjunctive treatment option after failed catheter-based VT ablation and anti-arrhythmic drug therapy.

ConclusionThe use of the S-ICD ™ was safe in patients with borderline or unclear indication for ICD implantation in our study. Of note, during a relatively short mean follow-up there were several appropriate therapies, especially for VF in these patients. On the other hand, oversensing also occurred in about 10% of patients, wh ile lead problems were not problematic in this collective. S-ICD™ implantation may be considered as a possible alternative in cases of borderline indications and clinical uncertainty when decision pro-ICD implantation is made. Incidence of arrhythmias was quite high and mostly consisted ...

This article reviews current knowledge regarding drug therapy for inherited arrhythmia syndromes (Brugada, early repolarization, long QT and short QT syndromes, and catecholaminergic polymorphic ventricular tachycardia), and acquired arrhythmias (idiopathic ventricular fibrillation, short-coupled torsade de pointes, outflow tract ventricular tachycardia, idiopathic left, papillary muscle and annular ventricular tachycardias). Expert opinion: In inherited arrhythmia syndromes, appropriate clinical and genetic diagnoses followed by proper selection and dosing of antiarrhythmic drugs are of utmost importance to prevent SCD, m...

AbstractIntroductionAcute hemodynamic decompensation during catheter ablation of ventricular tachycardia is associated with increased mortality. We assessed the effectiveness of mechanical circulatory support using a micro ‐axial percutaneous assist device in preventing acute hemodynamic decompensation.Methods and resultsTwenty ‐six consecutive patients with structural heart disease undergoing 28 ventricular tachycardia ablations between May 2013 and October 2017 were included. All patients presenting with left ventricular ejection fraction

While the increased mortality associated with flecainide in the Cardiac Arrhythmia Suppression Trial (CAST) still casts his shadow over flecainide cli...

ConclusionStudies comparing PVR and conservative therapy exclusively in adults with rTOF are lacking. After PVR, the incidence rates of death and ventricular tachycardia are both 1 per 100 patients-years. Pooled analyses demonstrated an improved functional status and a reduction in RV volumes.
