Temporal Stability and Precision of Ventricular Defibrillation Threshold Data [PDF]
, 1978 Over two-hundred measurements of the minimum damped sinusoidal current and energy for transchest electrical ventricular defibrillation (ventricular defibrillation threshold) were made to determine the stability and precision of threshold data in 15 ...

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023 Numerous T wave morphology biomarkers, which can supplement QTc assessment in long QT syndrome (LQTS), have been identified. Their diagnostic capabilities include differentiation of genotypes, identification of concealed LQTS, differentiating acquired LQTS from congenital LQTS; and determining multichannel versus hERG channel blockade.

Advantage of four-electrode over two-electrode defibrillators [PDF]
, 2015 Defibrillation is the standard clinical treatment used to stop ventricular fibrillation. An electrical device delivers a controlled amount of electrical energy via a pair of electrodes in order to reestablish the normal heart rate.

Rise in chronic defibrillation thresholds in nonthoracotomy implantable defibrillator. [PDF]
Circulation, 1994 BACKGROUND To establish the chronic stability of defibrillation thresholds (DFTs) in a transvenous cardioverter/defibrillator (TCD) system, we studied 37 consecutive patients with TCD systems implanted for > 6 months. METHODS AND RESULTS DFT was measured by a step-down method at ...

European Journal of Clinical Investigation, Volume 53, Issue 1, January 2023., 2023 Abstract Background The number of patients with cardiac implantable electronic devices (CIEDs) undergoing radiotherapy (RT) for cancer treatment is growing. At present, prevalence and predictors of RT‐induced CIEDs malfunctions are not defined. Methods Systematic review and meta‐analysis conducted following the PRISMA recommendations.

Is There an Effect of Amiodarone on the Defibrillation Threshold?
Japanese Heart Journal, 1993 The interaction between amiodarone and the defibrillation threshold (DFT) is still controversial. We present a case with dilated cardiomyopathy and recurrent sustained monomorphic ventricular tachycardia who received an automatic implantable cardioverter defibrillator (AICD) while under long-term amiodarone treatment.

Treatment of ineffective endocardial defibrillation with subcutaneous array: a case report
Türk Kardiyoloji Derneği Arşivi, 2017 Defibrillation threshold (DFT) testing is an important part of ICD implantation. After placement of the ICD generator, a DFT test is performed to evaluate the integrity of the ICD system and to confirm a successful defibrillation safety margin. More than

Defibrillation via the Elimination of Spiral Turbulence in a Model for Ventricular Fibrillation [PDF]
Physical Review Letters, Vol. 86, 3678-3681 (2001), 2001 Ventricular fibrillation, the major reason behind sudden cardiac death, is turbulent cardiac electrical activity in which rapid, irregular disturbances in the spatiotemporal electrical activation of the heart makes it incapable of any concerted pumping action.

Traumatic Tension Pneumothorax as a Cause of ICD Failure: A Case Report and Review of the Literature
Case Reports in Cardiology, 2014 Background. Tension pneumothorax can infrequently cause ventricular arrhythmias and increase the threshold of defibrillation. It should be suspected whenever there is difficulty in defibrillation for a ventricular arrhythmia. Purpose. To report a case of
