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.
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.

Regular, narrow complex tachycardia with a ventricular rate around 150 can be challenging. The differential includes sinus tachycardia, atrioventricular nodal reentrant tachycardia (AVNRT), atrioventr...
An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (AV dissociation).
A malignant form of polymorphic ventricular tachycardia that is characterized by HEART RATE between 200 and 250 beats per minute, and QRS complexes with changing amplitude and twisting of the points. The term also describes the syndrome of tachycardia with prolonged ventricular repolarization, long QT intervals exceeding 500 milliseconds or BRADYCARDIA. Torsades de pointes may be self-limited or may progress to VENTRICULAR FIBRILLATION.
Cardiac electrical stimulators that apply brief high-voltage electroshocks to the HEART. These stimulators are used to restore normal rhythm and contractile function in hearts of patients who are experiencing VENTRICULAR FIBRILLATION or ventricular tachycardia (TACHYCARDIA, VENTRICULAR) that is not accompanied by a palpable PULSE. Some defibrillators may also be used to correct certain noncritical dysrhythmias (called synchronized defibrillation or CARDIOVERSION), using relatively low-level discharges synchronized to the patient's ECG waveform. (UMDNS, 2003)
Implantable devices which continuously monitor the electrical activity of the heart and automatically detect and terminate ventricular tachycardia (TACHYCARDIA, VENTRICULAR) and VENTRICULAR FIBRILLATION. They consist of an impulse generator, batteries, and electrodes.
Abnormally rapid heartbeats originating from one or more automatic foci (nonsinus pacemakers) in the HEART ATRIUM but away from the SINOATRIAL NODE. Unlike the reentry mechanism, automatic tachycardia speeds up and slows down gradually. The episode is characterized by a HEART RATE between 135 to less than 200 beats per minute and lasting 30 seconds or longer.
