“…34 After adjustment for clinical risk factors, TCRT/HR loop area remained an independent predictor of cardiac death with hazard ratio 5.6 (P < 0.007) and SCD with hazard ratio 10.7 (P < 0.024). 34 Exercise-recovery hysteresis of TCRT might provide prognostic information on cardiac mortality and SCD. However, the parameter might be technically challenging to assess in patients.…”

“…Exercise-recovery hysteresis of TCRT was quantified by measuring the TCRT/HR loop area bounded by the exercise and first 3-minute postexercise recovery curves. 34 The HR-corrected TCRT/HR hysteresis was calculated by dividing the area with the HR decrement during the first 3 minutes of recovery. 34 During 45 ± 12 months follow up, 5.7% patients died, 2.6% were cardiac deaths and 1.9% were SCDs.…”

Background: Sudden cardiac death (SCD) remains a major public health problem. Current established criteria identifying those at risk of sudden arrhythmic death, and likely to benefit from implantable cardioverter defibrillators (ICDs), are neither sensitive nor specific. Exercise electrocardiogram (ECG) testing was traditionally used for information concerning patients' symptoms, exercise capacity, cardiovascular function, myocardial ischemia detection, and hemodynamic responses during activity in patients with hypertrophic cardiomyopathy.Methods: We conducted a systematic review of MEDLINE on the utility of exercise ECG testing in SCD risk stratification.Results: Exercise testing can unmask suspected primary electrical diseases in certain patients (catecholaminergic polymorphic ventricular tachycardia or concealed long QT syndrome) and can be effectively utilized to risk stratify patients at an increased (such as early repolarization syndrome and Brugada syndrome) or decreased risk of SCD, such as the loss of preexcitation on exercise testing in asymptomatic Wolff-Parkinson-White syndrome.Conclusions: Exercise ECG testing helps in SCD risk stratification in patients with and without arrhythmogenic hereditary syndromes.

“…Ferner rückt mehr und mehr die prognostische Wertigkeit einer ER bei Patienten mit akuten Koronarsyndromen in den Fokus des Interesses [3,4]. Hinsichtlich neuer nichtinvasiver elektrophysiologischer Parameter wurde erstmals ein interessanter Prädik-tor für den plötzlichen Herztod beschrieben, der nach einer Belastungsuntersuchung die Erholung des räumlichen QRS/ T-Winkels beschreibt [5].…”
