Fastest Way to Pull up ECG

Just my first Apple Watch (Series 9) to help monitor my heart rhythm due to recent serious cardiac issues. My arrhythmias are usually brief (2–5 seconds), and I’d like to catch them using the ECG app.

Right now, I have ECG in the Smart Stack, so I swipe up, tap it, and record. Is there a faster way? Is there a way to put a direct ECG button on the watch face?
