You might want to get a Kardia device to do a home EKG, or a smart watch-or ask your doctor for a patch monitor. Do you have a cardiologist to discuss this with? My cardiologist would be concerned about the jaw pain (or any left arm pain) from what he has told me.
If this happens again maybe you could go to the ER and it could be documented and diagnosed. I am sorry you went through that!
In my experience a PVC, a premature ventricular contraction, feels like a pause and then a fast double or triple beat. There are also PAC's and atrial flutter, and atrial fibrillation, which a doctor can differentiate for you.
We cannot diagnose or give medical advice here, only share our experience. I get afib with "rapid ventricular response" meaning heart rate above 190 and a big fish flopping around inside. When I was younger I sometimes had PVC's for a period of minutes or even hours.
Hope you can get a device and also consult a doctor or go to the ER. Good luck!
Thank you windyshores, I've never heard of a Kardia device and will look into it. My previous episodes have always involved the intense jaw pain, so the cardiologist knows about them and doesn't seem concerned. I appreciate the information!
