Oscilloscope Analysis
To precisely analyze the circuit after simulating it over spring break, I used Keysight’s MSOX4034A oscilloscope to measure the output signal and to determine characteristics like frequency.
Heart Rate
The heart rate came out to 1.3683 Hz, or about 82 BPM, similar to the 85 BPM I estimated using the online BPM counter.

Pacemaker
After disconnecting the heart output, the pacemaker’s heart rate came out to 1.1218 Hz, or about 73 BPM, very close the 72 BPM I estimated using the online BPM counter.
