Summary

This research study is a prospective, single-center, feasibility study designed to assess the possibility to detect hemodynamic changes during tachycardia episodes using tissue perfusion.

Detailed description

This study is being conducted to evaluate the feasibility to detect hemodynamic changes induced by supra-ventricular or ventricular tachycardia (SVT or VT) using tissue perfusion. Patients with a standard indication for either an electrophysiological study or an implantable cardioverter defibrillators(ICD) implant can be included into this study. Tissue perfusion and arterial blood pressure will be monitored and recorded throughout the electrophysiological procedure or ICD implant testing. The study will be conducted in two consecutive phases. After completion of study phase I the study phase II will commence. Study phase I will be an acute non-invasive study in patients with an indication for an electrophysiological study, in whom tissue perfusion will be measured non-invasively with an epi-cutaneous tissue perfusion sensor. Phase II will be an acute invasive study in patients with an indication for the implantation of an ICD, in whom the tissue perfusion sensor will be placed in the surgically prepared device pocket on the muscular pectoralis or between the muscular pectoralis major and muscular pectoralis minor.

Conditions

• Arrhythmias, Cardiac

Interventions

Type	Name	Description
PROCEDURE	High rate atrial and vetricular stimulation	The right atria and ventricle of the subject will be electrically stimulated at high rate mimicking tachycardia episodes using electrodes placed in the right atria and ventricle.
PROCEDURE	Ventricular Tachycardia induction	A programmed electrical stimulation protocol will be performed using an electrode placed in the right ventricle.
