a heart rhythm detector that detects the heart rhythm of a shock recipient; a manual mode controller that sets the defibrillator in the synchronous shock operating mode or the asynchronous shock operating mode; a shock module that causes the defibrillator to deliver a shock to the shock recipient according to the operating mode of the defibrillator; and an automatic mode controller that sets the defibrillator to the synchronous shock operating mode or the asynchronous shock operating mode depending on the detected heart rhythm of the shock recipient. ### Claim 2 (depends on 1) The defibrillator of claim 1, in which the manual mode controller sets the defibrillator in the synchronous shock operating mode depending on an input. ### Claim 3 (depends on 1) The defibrillator of claim 1, in which the manual mode controller sets the defibrillator in the asynchronous shock operating mode depending on an input. ### Claim 4 (depends on 2) The defibrillator of claim 2, wherein the input comprises an input from an operator of the defibrillator. ### Claim 5 (depends on 1) The defibrillator of claim 1, wherein the automatic mode controller sets the defibrillator after the defibrillator has delivered a shock. ### Claim 6 (depends on 1) The defibrillator of claim 1, wherein the automatic mode controller sets the defibrillator after the defibrillator has delivered a shock. ### Claim 7 (depends on 1) The defibrillator of claim 1, wherein the automatic mode controller sets the defibrillator to the synchronous shock operating mode without an input from an operator. ### Claim 8 (depends on 7) The defibrillator of claim 7, wherein the automatic mode controller sets the defibrillator to the synchronous shock operating mode without an input from the shock recipient. ### Claim 9 (depends on 8) The defibrillator of claim 8, wherein the input from shock recipient is representative of a condition of the shock recipient. ### Claim 10 (depends on 1) The defibrillator of claim 1, wherein the automatic mode controller sets the defibrillator to the asynchronous shock operating mode without an input from an operator. ### Claim 11 (depends on 10) The defibrillator of claim 10, wherein the automatic mode controller sets the defibrillator to the synchronous shock operating mode without an input from the shock recipient. ### Claim 12 (depends on 11) The defibrillator of claim 11, wherein the input from the shock recipient is representative of a condition of the shock recipient. ### Claim 13 (depends on 1) The defibrillator of claim 1, wherein the synchronous shock operating mode operates to deliver a shock that is timed to correlate with a certain QRS complex in a heart rhythm. ### Claim 14 (depends on 1) The defibrillator of claim 1, wherein the asynchronous shock operating mode is distinct from the synchronous operating mode in which delivery of a shock is timed independent of a certain QRS complex in a heart. ### Claim 15 (depends on 14) The defibrillator of claim 14, wherein the heart rhythm detector detects at least one of an electrocardiogram (ECG) or a pulsatile blood flow monitor to determine the heart rhythm. ### Claim 16 (depends on 15) The defibrillator of claim 15, in which the automatic mode controller sets the defibrillator in the synchronous shock operating mode after the shock has been delivered, when the detected ECG includes a QRS complex after the shock has been delivered. ### Claim 17 (depends on 1) The defibrillator of claim 1, further comprising: a processor that includes the automatic mode controller. ### Claim 18 (depends on 1) The defibrillator of claim 1, wherein the defibrillator comprises an external defibrillator. ### Claim 19 (depends on 1) The defibrillator of claim 1, wherein the heart rhythm detector detects the heart rhythm of the shock recipient a plurality of times after the shock has been delivered to the shock recipient. ### Claim 20 (depends on 1) The defibrillator of claim 1, wherein the heart rhythm detector analyzes the heart rhythm of the shock recipient before a shock is delivered.
