Why would the Instrumentation be better to record the ECG ?
Unfortunately, the differential amplifier turns out to be rather limited in its performance because of the low input impedance of (R2 + R1). To improve this, two bootstrapped buffer amplifiers (which are just op-amps with unity gain) are commonly added, which results in the simple instrumentation amplifier:
