Abstract: Methods of and systems for ablating cardiac tissue is disclosed. One example method includes monitoring an electrical signal of a heart of a patient. The electrical signal represents the heart beating. The method further includes determining, with an electronic processor and based on the electrical signal, an end-diastolic time period at an end of a diastolic time period during which diastole of the heart has occurred during a previous cardiac cycle. The method further includes determining, with the electronic processor and based on the electrical signal, that another cardiac cycle has begun. The method further includes causing, with the electronic processor, an electrode to deliver pulsed field ablation (PFA) energy to the heart during at least a portion of a time in which the end-diastolic time period of the another cardiac cycle is expected to occur.

Abstract: Evaluating a cardiac lesion formed by an ablation procedure, by receiving, by processing circuitry and following conclusion of delivery of ablation energy, a bioelectrical signal from an electrode proximate to a target location of cardiac tissue for the cardiac lesion; determining, by the processing circuitry, one or more characteristics of the received bioelectrical signal in a frequency band of the received bioelectrical signal; and estimating, by the processing circuitry, an efficacy of the cardiac lesion based on a comparison of the determined amplitude of the bioelectrical signal and a threshold amplitude.

Abstract: A medical device system including a physiological sensor and ultrafiltration unit senses a physiological signal in a patient and computes a fluid status measurement of the patient using the physiological signal. Ultrafiltration therapy is delivered to the patient according to a therapy delivery control parameter established in response to the fluid status measurement.

Abstract: Control of conduction through a heart is described. A lead with a proximal end and a distal end is provided. The distal end of the lead is inserted into a target area. An agent is delivered through the lead to the target area. Delivery of the agent is monitored via a closed loop feedback system.
