It was the 1 year checkup appointment and i told him that sometimes i get these like back to pack pvc feelings and it like kinda feels like it flutters. Now i have to go for an echo next week and get a even monitor. He says its most likely a benign pvc thing. Or else he said it could be something else more serious, but he wouldnt tell me what it was. So does anyone know what the serious problem could be? Im a little worried.
