### input:
II I take Metoprolol Succ Extended 25 mg tab twice a day. Earlier this evening I ate a piece of chocolate and shortly after, I noted I was having palpitations. I took a Metoprolol tablet as it was time for my evening dose. I continued to note the palpitations. My son took me to an Urgent Care Center. An EKG showed no acute injury and an occasional PVC. EKG and Lab work showed no acute abnormality other than a rare PVC. Home now for a couple of hours and having more frequent PVC s. I called the Urgent Care and the ED physician had me take another Metoprolol as long as my systolic BP was greater that 120 and it was 190/63. I took the med and my BP is back to normal, but I am still having PVC S. A PVC occurs every 4th beat. I have no chest pain and no SOB. I do have a little discomfort in my upper left arm. No nausea and no SOB

Hello, Brief answer: Your condition just needs to be followed up. Explanation: My opinion is that PVC occurrence in your case was aggravated by emotional stress or eating chocolate which might increase the level of serotonin in your blood and caused such condition. The information provided by you is not sufficient to provide a good opinion. If someone comes to me with this condition I would ask them about their heart condition or their medications if any may causing that as a side effect, also check their blood pressure as high readings may lead to that. Conclusion: I suggest you check your blood pressure avoid any emotional stress and if so review with your cardiologist. Hope I have answered your query. Let me know if I can assist you further.
