Dual-chamber implantable cardioverter-defibrillators (ICDs) may improve detection of atrial fibrillation as well as differentiation of tachycardias. However, this advantage is undermined by complications associated with the second electrode, which is required in conventional dual chamber devices. Therefore, BIOTRONIK has developed a new electrode called the LinoxSMART S DX that, when used in conjunction with the Lumax DX ICD, offers dual-chamber detection without the risks associated with the...

Chambers of the Heart

The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles. Deoxygenated blood from the body is received in the right...

FAQs
The device continuously senses electrical activity through a single transvenous lead positioned in the right ventricle. Its detection function evaluates the ventricular rhythm and identifies patterns consistent with ventricular tachycardia or ventricular fibrillation. This sensing step is essential because therapy is delivered only after the device recognizes a rhythm that may require antitachycardia pacing or an electrical shock.
Antitachycardia pacing attempts to treat a detected ventricular tachycardia using pacing activity rather than a high-energy shock. If that approach does not restore a safer rhythm, or if the detected rhythm is ventricular fibrillation, the device can deliver an electrical shock. These therapy functions give the single-chamber ICD more than one way to respond to dangerous ventricular arrhythmias.
Sensing and detection settings determine how the device interprets ventricular electrical activity and when it initiates therapy. Appropriate programming links rhythm recognition to the available treatments, including antitachycardia pacing or shock delivery. Because the device must respond to life-threatening ventricular arrhythmias while monitoring continuously, programming is a central part of device management rather than a secondary technical detail.
Implantation places one transvenous lead in the right ventricle and connects it to the ICD system. Clinicians then configure the device so it can sense ventricular rhythm, identify ventricular tachycardia or ventricular fibrillation, and provide the intended therapy. Follow-up evaluates device function and programming over time, supporting continued management after the initial implantation.
Clinicians may consider this device for patients at risk of life-threatening ventricular arrhythmias, including some individuals with cardiomyopathy or a history of cardiac arrest. The relevant clinical concern is prevention of sudden cardiac death through prompt rhythm detection and treatment. Device selection remains part of cardiovascular decision-making, with implantation and programming tailored to the patient’s arrhythmia risk.
Long-term follow-up can assess whether the device continues to sense ventricular electrical activity, recognize dangerous rhythms, and deliver antitachycardia pacing or shocks when indicated. It also provides an opportunity to review programming and device performance. This ongoing evaluation is important because the ICD’s preventive role depends on reliable monitoring and appropriately configured therapy functions.
