trouble sleeping pvcs or not

For the past two days every time I try and sleep it feel like I wake up gasping for air, it happens a few times before I'm finally able to drift away into a deep sleep, I experienced this before right before my first ablation but it went away and wasnt as half as bad, as I have went thru the last couple of days. Its really scary and im afraid to fall asleep thinking that I will stop breathing, I dnt no if I'm having pvcs in my sleep or is it something else, and also when this happens sometimes when I wake it feels like my heart is vibrating not tachycardia but literally vibrating, I called my Dr. This morning about this and is awaiting his phone call. Has anyone else experienced this, could this be sleep apnea, or something worse

Thanks, it's all so frustrating, right when you think you might just be ok something else happens!!!!
