1. Circuitry for obtaining electrocardiogram (ECG) signals associated with an ambulatory patient, the circuitry comprising:
- a first integrated circuit (IC) configured to accept differential channels of ECG signals, process the ECG signals, and store the processed ECG signals, wherein capacitors are coupled to the first IC to correct out-of-range ECG signals;
a second IC in communication with the first IC, the second IC including a microcontroller; and
a third IC in communication with the second IC, the third IC configured to store the processed ECG signals from the first IC,wherein each of the second and third ICs is selectively powered in response to an approximately full capacity of the stored processed ECG signals in the first IC.
