Can PVCS be caused by stress?

As a medical professional with expertise in cardiology, I can provide you with an informed response to your question regarding PVCs, or premature ventricular contractions. PVCs are extra heartbeats that occur when the ventricles in your heart beat earlier than they should. They are quite common and can be felt as a fluttering, flip-flopping, or skipped heartbeat. While PVCs are usually harmless, they can sometimes be a sign of an underlying heart condition. Stress can indeed be a factor in the development of PVCs. When you're stressed, your body releases stress hormones, such as adrenaline, which can increase your heart rate and potentially trigger PVCs. Additionally, stress can exacerbate existing heart conditions or other factors that may contribute to the occurrence of PVCs. However, it's important to note that PVCs can also occur in people without any heart disease and are often not a cause for concern. If you're experiencing frequent PVCs, especially if they're accompanied by other symptoms like chest pain, shortness of breath, or dizziness, it's important to consult with a healthcare provider to rule out any serious underlying conditions.

In most cases of occasional PVCs the underlying cause cannot be identified. ... Certain medications, alcohol, illegal drugs and high levels of adrenaline due to stress, exercise or caffeine also can cause PVCs.
