Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Whenever I have the skipped beat sensations, there's like an anxious feeling in my chest and sort of a feeling like my body is heavy. It is the same sensation that I get during panic attacks but much less severe. The sensation never lasts. It goes away immediately after the beat. I'm terrified these fuckers are going to kill me. I have no idea why all of a sudden these are happening so frequently.. ### Response: It sounds like PVCs (premature ventricular contractions) which feel weird but arent life threatening..
