In brief: Best to get checked
Pvcs are very common and can occur for many reasons, most not very dangerous.
If the fast rate is from drugs like caffeine or ocaine, they can make the heart muscle irritable and prone to extra beats. With the stress of a fast heartbeat, perhaps problems with blood flow (ischemia) or anatomy (muscle size or conduction) may play a role. Best to get good history, exam and at least ekg to check.
