Current status of antitachycardia devices.

Current status of antitachycardia devices.

With the limitations of currently available modalities for treating clinically important tachycardias, the role of implanted antitachycardia devices will continue to expand. The challenge of the future will not only involve continued technological advances but the socioeconomic impact of this efficacious but expensive mode of therapy in an era of increasing financial restraints.

Clinical Progress Series Current Status of Antitachycardia Devices

M anagement of hemodynamically significant supraventricular and ventricular tachyarrhythmias is often a difficult problem for the practicing cardiologist. Not only is there considerable controversy regarding the appropriate technique to guide the selection of therapy (i.e., noninvasive versus invasive techniques), but the available therapeutic options continue to expand. Antitachycardia therapy...

Tachycardia detection in implantable antitachycardia devices.

We have developed a microcomputer algorithm for tachycardia identification suitable for use in an implanted antitachycardia pacemaker. The algorithm distinguishes atrial, ventricular, and AV reentrant tachycardia, while ignoring high rates due to sinus tachycardia. A new method whereby the pacemaker delivers an atrial extrastimulus has been developed for distinguishing paroxysmal 1:1 tachycardi...

Current status of liver tumor ablation devices.

The liver is a common site of disease for both primary and metastatic cancer. Since most patients have a disease that is not amenable to surgical resection, tumor ablation modalities are increasingly being used for treatment of liver cancer. This review describes the current status of ablative technologies used as alternatives for resection, clinical experience with these technologies, currentl...
