DAD
Figure 3: Illustration of a DAD following a train of 20 stimuli at 3 Hz. The first action potential reached threshold producing a triggered arrhythmia. The final oscillation (15 mV) is a DAD that failed to reach
threshold.
EAD
Figure 4: Illustration of an EAD that occurred during the 2 minutes of quiescence between 2 trains of stimulation. Abnormal sustained
rhythm develops after the second action potential with EAD.
