Boston Scientific Corporation develops, manufactures, and markets medical devices used in various interventional medical specialties worldwide.
A lead designed for use in the atrium; it may be endocardial (within the heart) or epicardial (attached outside the heart).
Industry:Medical devices
A partial or total disruption of the conduction of electrical impulses from the atria to the ventricles.
Industry:Medical devices
A cluster of cells located in the wall between the right and left atria, just above the ventricles. This part of the heart's electrical pathway helps carry signals from the atria to the ventricles.
Industry:Medical devices
A type of supraventricular tachycardias (SVT). Accounts for about 60% of all fast heart rates that start in the upper part of the heart. AVNRT occurs when the A-V node has an extra electrical pathway in the heart linking the right atrium to the A-V node, a kind of "short circuit." The paths are different and unique; one is fast and the other slow. Symptoms include attacks of palpitations, dizziness, and syncope; heart rates can achieve 150-230 beats per minute. These attacks start and stop suddenly. .
Industry:Medical devices
The normal time sequence for an atrial contraction followed, after a fraction of a second, by a ventricular contraction.
Industry:Medical devices
The two valves, one in each side of the heart, between the atria and ventricles. The tricuspid valve is located on the right side of the heart, and the mitral value is located on the left side.
Industry:Medical devices
One of the upper two chambers of the heart (plural: atria). The right atrium collects deoxygenated blood and the left atrium collects oxygenated blood before it is passed to the ventricles.
Industry:Medical devices
A surgically implanted device that monitors the heartbeat and delivers electrical impulses to correct an abnormally fast rhythm and restore a regular heartbeat. The AICD system usually consists of an implanted pulse generator and one or more leads. The system is adjusted using an external programming device. Also known as an implantable cardioverter defibrillator (ICD).
Industry:Medical devices
A bacterial infection of the heart lining or valves. People with abnormal heart valves or congenital heart defects are at increased risk of developing this disease.
Industry:Medical devices
The electrocardiogram (ECG) waveform that represents ventricular depolarization. If all components are present, the complex is made up of Q-, R- and S-waves. The duration of a normal QRS complex is approximately 80-120 ms.
