    摘要: A method of atrial rotational activity pattern (RAP) source detection is provided which includes detecting, via a plurality of sensors, electro-cardiogram (ECG) signals over time, each ECG signal detected via one of the plurality of sensors and indicating electrical activity of a heart. The method also includes determining, for each of the plurality of ECG signals, one or more local activation times (LATs) each indicating a time of activation of a corresponding ECG signal. The method further includes detecting whether one or more RAP source areas of activation in the heart is indicated based on the detected ECG signals and the one or more local LATs. Mapping information of the detected RAP source areas of activation in the heart is also generated for providing one or more maps.

    摘要: The disclosed technology includes a method of ablating tissue including positioning an electrode into contact with tissue and applying a first ablation signal to the tissue. The method can include forming a first lesion comprising a first depth with little or no first temperature change in a temperature of the tissue. The method can include applying a second ablation signal to the tissue different from the first ablation signal. Applying the second ablation signal to the tissue can include forming a second lesion comprising a second depth and generating a second temperature change in the tissue different from the first temperature change by at least 10°C. The method can include forming a combined lesion comprising the first lesion and the second lesion and comprising a combined size. The combined depth can be about 20% to about 40% greater than either of the first depth and the second size.

    摘要: A catheter may be adapted to map a chamber of the heart. The catheter may include a magnetic and/or ultrasound sensor for navigation. The body of the catheter may be pliable and configured to form a predetermined shape upon exiting a catheter sheath. Upon exiting the catheter sheath, the catheter body may be configured to form one or more loops, and the loops may be non-overlapping loops. In some examples, the non-overlapping loops may be concentric loops. Alternatively, the catheter body may be configured to form one or more splines. The catheter body may include an embedded electrode assembly. The electrodes of the electrode assembly may be may be arranged in one or more rows and configured to detect a wave front. The electrode assembly may also be configured to generate and activation sequence and determine a direction of an activation source. The electrode assembly may also be configured to determine the type of activation source, for example a rotational activation source, a focal activation source, and a single-wide activation source.
