Popis:	A 69-year-old patient with a single chamber cardioverter defibrillator (ICD) implanted in primary prevention of sudden cardiac death (heart failure in dilated cardiomyopathy) was admitted to the hospital due to ventricular tachycardia (VT) not recognized by the ICD. After control of ICD, it was concluded that the cause of the absence of ICD intervention was the classification of arrhythmia by Wavelet as a supraventricular. Default settings have been used since the implant – (Wavelet – 70%, Onset and Stability off). The arrhythmia was within the VT detection zone. There were two possible solutions: turning Wavelet off or reducing its threshold. However, considering the absence of supraventricular arrhythmias, the Wavelet function was disabled.
