Hi all, since acquiring AF I've been experiencing a load of ectopics. I understand PACs are from the atria and PVCs are from the ventricles. Is there a way to tell them apart? I've had 48hr holter and I was told I had a number of PVCs. Since then my 'ectopic load' appears to have increased (possibly with switching from Tildiazem to Bisoprolol). I have a Kardia so I can pick the ectopics up quite easily on there. Is there a way to understand, either via the Kardia or simply through understanding the sensation, if an ectopic is a PAC or a PVC? Thanks in advance!
