Source and direction would be killer features. Imagine holter monitors that can sit beside your bed as you sleep (tossing and turning), instead of wearing them, or instant continuous ECG data during triage. Many heart attacks are misdiagnosed (especially in women) and instant continuous ECG readings (possibly from multiple people at once) would be incredible!
