“…The only independent variable related to the lengthening of the PPI-TCLd was the QRS amplitude: a QRS> 120 msec was associated with a sensitivity and specificity of 66% and 79% respectively to a PPI-TCLd> 200 msec. [16] However, other authors did not observe any significant difference in ATP efficacy for variations of QRS length, neither in vivo [12] nor in computational models [50].…”

“…The authors in fact state that the variability percentage of the VTCL prior to first burst delivery is considered an independent predictor for ATP effectiveness. [16] For faster VTs (FVT), as already stated, more aggressive therapies are preferred due to the lower ATP efficacy and their higher correlation with hemodynamic instability, which requires a faster resolution of the arrhythmical event. The use of a single burst is encouraged, mostly during charge (DC) of ICD generator.…”

Introduction: Antitachycardia pacing (ATP) is one of the therapies provided by an implantable cardioverter defibrillator (ICD) for the treatment of ventricular arrhythmias (VA). Successful ATP leads to avoidance of shock, that is related to an increase in mortality and morbidity. Methods and Results: A total of 63 documents have been obtained by using the key term “Antitachycardia pacing” in PubMed, focusing on optimal ATP and ICD programing to reduce inappropriate or avoidable therapies, predictive factors of ATP efficacy and latest technologies and devices still in experimentation. Conclusions: Antitachycardia pacing confirms to be a good therapeutic tool to interrupt ventricular arrhythmias. An optimal ICD programming could lead to the reduction of inappropriate or avoidable ATP therapies. Furthermore, a better knowledge in predictive factors of ATP efficacy not only could better orient physicians on the device to implant, but also could allow for a better arrhythmic risk stratification.

É interessante que os limitadores de tempo, como SRD (Boston Scientific) e Timeout, sejam desabilitados, pois esses recursos ignoram a discriminação de um evento classificado como TSV após o período preestabelecido e liberam a terapia que seria inapropriada.…”

Electrical Storm in Patients with Inappropriate Implantable Cardioverter-Defibrillator Therapy: Current Trends in Clinical Practice between Guidelines and Technology Progress

The term “Electrical Storm” (ES) indicates cardiac electrical instability manifested by several episodes of ventricular tachyarrhythmias within a short time. In the contemporary implantable cardioverter-defibrillator (ICD) era, ES is defined as recurrent (three or more separate episodes) of ICD discharges over 24 hours. Some ESs are due to inappropriate repetitive shock and are potentially lethal for the patient. The most common causes of inappropriate ICD shock include supraventricular tachycardia with high ventricular response and oversening of peaked T waves or R wave, myopotentials or electrical noise. Appropriate diagnosis and treatment are critical in the Emergency Department. To approach these patients systematically, it is important to understand, that there are four causes of shock. Modern ICD incorporate sophisticated tachycardia detection algorithms within their programming designed to minimize devices’ detection mistakes and ICD-related information can also be checked using remote home monitoring systems. However, these opportunities are often not utilized to their full benefit. Thus, careful attention should be paid to the programming of the device. Fine tuning of the detection and differentiation algorithms is critical, and best done by a practitioner who understands the subtle differences among the different manufacturers. The racommendations for those problems should be revised.
