This channel includes news and new technology innovations for cardiac electrophysiology (EP) systems, techniques and devices using in EP labs. This includes implantable EP devices, pacemakers, implantable cardioverter defibrillators (ICD), cardiac resychronization therapy (CRT), ablation technologies, left atrial appendage (LAA) occlusion, atrial fibrilation (AF) and Holter monitors.
Chest X-ray from a patient included in the study. Posteroanterior view, of a 79-year-old man with history of a previous pacemaker, with abandoned right atrial and right ventricular pacing leads on the right side at time of new cardiac resynchronization therapy defibrillator implant on the left side. Arrows indicate a nodular opacity in the right midlung concerning for mass. Find more images of patients in this study in Radiology: Cardiothoracic Imaging.
The Medicalgorithmics PocketECG Holter monitor offers real-time, remote, wireless ECG recording and tracking. Real-time data review may be able to help diagnose an arrhythmia quickly, reducing the amount of time the patient needs to be monitored. Also, 24/7 data offers a more complete picture of the patient's health, rather than fragments of data from older Holter and event monitor systems.
The study used cadaver hearts that were images with contrast enhanced MRI and the images used to create a 3-D computation model of the electrical activation in the heart and how it was influenced by adenosine and ablation. Find more images in the original article
The Mesuron Inc. Avalon-H90 uses magnetometers to detect myocarditis in patients without any physical contact. It uses ventricular repolarization dynamics analysis software to look for abnormalities. The vendor said it is more specific than using ECG. It detects the multidimensional dynamics of the electrical activity caused by differences in functions of electrical action potential of normal heart tissues and abnormal ones with hypoxia.
New cardiac monitoring technologies allow for longer duration data collection. The Medtronic Reveal Linq implantable cardiac monitor allows for 24/7 monitoring for up to three years. This might not be necessary for most patients, and there are several newer Holter monitors that can record up to several days or several weeks of data in real-time.
The FDA granted 510(k) clearance for the SentiAR CommandEP system, the first holographic guidance system to be used during an invasive electrophysiology (EP) lab cardiac procedures. The system allows electrophysiologists to visualize 3-D electro-anatomic models in real-time, via a wearable headset and offer a truly handsfree control interface providing superior visualization, allowing them to navigate accurately within the heart during a cardiac ablation procedure.
An example of the new generation of inexpensive, wearable cardiac monitors that are seeing increased usage. This is the Cardiac Insight Cardea Solo device. After the monitoring period is over, the wearable patch is torn open to retrieve a data pod that is inserted into a reader to download the data. The software automatically creates reports based on the data, complete with waveforms for various cardiac measures.
