Abstract
A method of treating a patient in cardiac arrest (e.g., in fibrillation, electrochemical dissociation, or asystole), the method comprising delivering an agent for enhancement of cardiac function to the coronary arteries of the patient; and microperfusing the patient's cardiac tissue by electromagnetically stimulating the cardiac issue at an energy level below a threshold sufficient to defibrillate the heart.
Claims5
Apparatus for treating a patient in cardiac arrest (e.g., in fibrillation, electrochemical dissociation, or asystole), the apparatus comprising:
- circuitry for generating microperfusing pulses to the patient's cardiac tissue, wherein the microperfusing pulses stimulating the cardiac tissue at an energy level below a threshold sufficient to defibrillate the heart;
- and
- circuitry for generating and pacing pulses and/or a defibrillation pulse to the patient,
- wherein the microperfusing, pacing, and/or defibrillation pulses are generated by varying the duty cycle, shape, and/or rate of delivery of a series of pulses delivered from an energy storage device.
Apparatus for treating a patient in cardiac arrest (e.g., in fibrillation, electrochemical dissociation, or asystole), the apparatus comprising:
- circuitry for generating a pacing pulse to the cardiac tissue;
- and
- circuitry for generating a defibrillation pulse to the cardiac tissue,
- wherein the pacing pulse has substantially the same waveform as the defibrillation pulse except for a difference in amplitude.
