Long-term treatment is required for patients with a congenital long QT-interval syndrome. Treatment choices include beta-blockers, permanent pacing, implantable cardioverter-defibrillator (ICD), or a combination. [merckmanuals.com]

The efficacy of treatment with class I,I,I antiarrhythmic drugs was not apparent but verapamil had an excellent therapeutic effect for it. [link.springer.com]

There are some interesting findings that shed some light into the understanding of the mechanism and etiology of IVF. At almost 8 decades after the original description of IVF [ 1 ], the etiology of this disorder still remains a mystery. [omicsonline.org]

After rhythm stability was achieved, the etiological study was completed by performing cardiac magnetic resonance imaging, which was normal ( Figure 3 ). [elsevier.pt]

The authors stated that this is a good example of the power of genetic diagnosis to direct the selection of appropriate therapy for patients with diseases of heterogeneous genetic etiology. [genome.jp]

The pathophysiological basis of long-QT syndrome (LQTS) is prolongation of cardiac ventricular repolarization by acquired factors such as drug exposure or genetic variation in the proteins controlling transmembrane ion-concentration gradients ( 8, 9 ) [pnas.org]

Unlike the other types of antiarrhythmic agents including beta-blockers and amiodarone, verapamil is in our experience the only drug apparently active on the arrhythmias; however, it does not prevent sudden death. [ncbi.nlm.nih.gov]
