I ended up going straight to the ER, and fortunately the doctors caught the trigeminy on the ECG. The recovery
phase after exercise
, when your heart rate is decreasing, is obviously a more likely time for PVCs and PACs to flare up, as the pulse is starting to slow...I also get the odd PVC/PAC during a run (skip sensation, flip flop or a hard thud). I think the adrenaline from the workout lingers in our system, and the opportunity for a PVC attack presents itself as we cool down.
