PVCs:
PVCs are premature ventricular contractions which are quite common in the general population. In the evaluation of PVCs one must ask whether or not there is a structurally normal heart and whether or not there are symptoms. PVCs in the presence of a structurally normal heart are virtually benign. There is currently no treatment of PVCs in any situation which improves survival. However, beta blockers may improve symptoms.
I am not aware of any direct association between PVCs and a sore throat. However, any situation which triggers an increased adrenaline level may cause an increase in PVCs. Your sore throat likely resulted in an increase in adrenaline which may have played a role in your PVCs. One may also avoid alcohol, caffeine, tobacco and stimulants such as those found in decongestants to reduce PVCs.
Thanks for your question,
