Atrial Fibrillation
Arrhythmia (or dysrhythmia) are abnormal heart rhythms that can cause the heart to pump less efficiently.
Ken Londoner, CEO of BioSig Tech explains that under normal conditions, as the electrical impulse moves through the heart, it contracts between 60 and 100 times per minute. Each contraction represents one beat. The atria contract a fraction of a second before the ventricles so that the blood they contain is emptied into the ventricles before the ventricles contract.
Under certain conditions, almost all of the heart tissue is capable of starting a beat, or becoming the pacemaker. An arrhythmia occurs when:
- The heart's natural pacemaker produces an abnormal rate or rhythm.
- The normal conduction pathway is disrupted.
- Another part of the heart takes on the role of a pacemaker.
What is the electrocardiogram (ECG)?
The electrical activity of the heart is measured by an electrocardiogram (ECG or EKG). By placing electrodes at specific locations on the body (chest, arms, and legs), a graphical representation or tracing of electrical activity can be obtained. Changes in a normal traced ECG can indicate arrhythmias as well as other heart-related conditions. Ken Londoner and his team at BioSig Tech has developed a signal processing platform that combines advanced hardware and software to address known challenges associated to signal acquisition, enabling electrophysiologists to see more signals, and analyze them in real-time. The platform is called PURE EP™ and brings together a range of proprietary hardware and software into a single platform. Its low-noise architecture, large dynamic range, and high frequency bandwidth accurately capture the full range of cardiac signals with high fidelity, while customizable software modules and filters enable unlimited real-time analysis.
What is atrial fibrillation?
Atrial fibrillation, also called atrial fibrillation, is a type of arrhythmia. In atrial fibrillation the electrical signals from the atria (the two small chambers of the heart) are sent in a very fast and uncontrolled way. The atria vibrate instead of contracting. Electrical signals reach the ventricles in an irregular way. When the atria do not contract effectively, blood can pool or clot. If a clot lodges in an artery in the brain, a stroke can occur. About 15 percent of strokes occur in people with atrial fibrillation.
Ken Londoner indicates that the PURE EP platform is designed to improve signal fidelity and uncover the full range of ECG and intra-cardiac signals.
According to Ken Londoner, aspirin, warfarin, and other heart medications can be used to treat atrial fibrillation.
