Mechanistically based mapping of human cardiac fibrillation
The mechanisms underpinning human cardiac fibrillation remain elusive. In his 1913 paper 'On dynamic equilibrium in the heart', Mines proposed that an activation wave front could propagate repeatedly in a circle, initiated by a stimulus in the vulnerable period. While the dynamics of activation and recovery are central to cardiac fibrillation, these physiological data are rarely used in clinica...
متن کاملBasic Science for the Clinical Electrophysiologist Phase Mapping of Cardiac Fibrillation
Phase is a descriptor that tracks the progression of a defined region of myocardium through the action potential and has been demonstrated to be an effective parameter in analyzing spatiotemporal changes during fibrillation. In this review, the basic principles behind phase mapping are presented mainly in the context of ventricular fibrillation (VF), atrial fibrillation (AF), and fibrillation f...
متن کاملCurrent Status and Future of Cardiac Mapping in Atrial Fibrillation
AF is a major concern in general population worldwide. Every year, 3 million suffer from AF related stroke, 1.5 million die from AF related stroke within a year, and 1 million are severely disabled by AF related stroke. Only 1% of AF patients underwent a treatment such as ablation or AF surgery. 99% remain as they are or prophylactic anticoagulation medication only. The reason why is due to the...
متن کاملTheoretical considerations for mapping activation in human cardiac fibrillation.
Defining mechanisms for cardiac fibrillation is challenging because, in contrast to other arrhythmias, fibrillation exhibits complex non-repeatability in spatiotemporal activation but paradoxically exhibits conserved spatial gradients in rate, dominant frequency, and electrical propagation. Unlike animal models, in which fibrillation can be mapped at high spatial and temporal resolution using o...
متن کاملMapping of atrial fibrillation.
Cardiac mapping has been defined as: "a method by which cardiac signals are recorded from multiple sites of the heart and spatially depicted as a function of time in an integrated manner". It requires determination of the local activation time at each electrode and the creation of activation maps which provide a spatial model of the activation sequence. With respect to atrial fibrillation, mapp...
