Sure: Depends how long you use it. This can be 5 seconds, or minutes, or one day or one week or even longer...

Yes: Only if it occurs during the few seconds that the ECG study samples. An event recorder may sample thousands to hundred of thousands to millions of heart cycles thus increasing the probability to discover abnormal heart beats over time.
