Ventricular tachycardia rate and morphology determine energy and current requirements for transthoracic cardioversion.
BACKGROUND The electrical current and energy required to terminate ventricular tachyarrhythmias are known to vary by arrhythmia: Ventricular tachycardia (VT) is generally considered to require less energy than ventricular fibrillation (VF). The hypothesis of our study was that current requirements for transthoracic termination of VT are further determined by VT rate and QRS complex morphology. ...
متن کاملAutomatic Rhythm Analysis Using SPART Method
Accurate identification of ectopic beats is important in frequency HRV analysis. It may be done by classification of QRS planar loop morphology. The objective of this research was to compare results of QRS morphology analysis in different spatial planes: frontal, horizontal, and preferential. The preferential plane of a QRS loop was found with modijied SPART method. Fourier descriptors of plane...
متن کاملA Case of Left Bundle Branch Block-shaped wide QRS Complex Tachycardia with diagnostic Ambiguity on a Surface Electrocardiogram
In cases of tachycardia with a broad QRS complex, it is important to differentiate between supraventricular tachycardia (SVT) and ventricular tachycardia (VT). Electrocardiogram (ECG)-based differential diagnoses include VT vs. SVT with aberrant conduction, pre-existing bundle branch block (BBB), intraventricular conduction disturbances, and pre-excitation. Several criteria have been described ...
متن کاملCardiac resynchronisation therapy is not associated with a reduction in mortality or heart failure hospitalisation in patients with non-left bundle branch block QRS morphology: meta-analysis of randomised controlled trials.
OBJECTIVES Recently published clinical guidelines recommend cardiac resynchronisation therapy (CRT) for patients with heart failure (HF) with reduced LVEF and non-left bundle branch block (non-LBBB) QRS morphology. We sought to define the potential benefit of CRT in these patients through meta-analysis of randomised controlled trials (RCTs) that have reported outcomes in patients with non-LBBB ...
متن کاملInfluence of Intrinsic Myocardial Conduction on Paced QRS Morphology During Cardiac Resynchronization Therapy Follow up
We report two cases of patients of cardiac resynchronization therapy (CRT) whose ECGs, during follow up, showed different paced QRS morphology as compared to those of immediate post-device implantation. Parameters of leads, including sensitivity and capture thresholds, were unchanged. There was no lead dislodgement confirmed on fluoroscopy. The ECGs obtained in device off mode showed different ...
