Heart PVC Symptoms, Treatments, and Further Information

Premature ventricular contractions (PVCs) are a common type of abnormal heartbeat that originates in the lower heart chambers. These irregular heartbeats can feel like the heart has skipped a beat or cause a fluttering sensation.

Most PVCs are benign and do not require treatment if they do not cause symptoms or complications. However, for those with frequent PVCs or heart disease, treatment may be recommended.

Common Causes of PVCs

While structural heart disease can cause PVCs, there are several non-structural causes that are more frequent. These include:

  • Stress: High levels of anxiety can trigger irregular heartbeats, including PVCs.
  • Caffeine: Intake of caffeine can stimulate the heart and provoke PVCs.
  • Fatigue or Lack of Sleep: Lack of rest can precipitate PVCs.
  • Electrolyte Imbalances: Abnormal levels of potassium, magnesium, or calcium can cause PVCs.
  • Stimulant Use: Some medications or recreational substances can induce PVCs.
  • Advancing Age: As people age, the likelihood of PVCs increases, even without heart structural changes.
  • Gastroesophageal Reflux Disease (GERD): Irritation from this condition can induce PVCs.

In some cases, valvular abnormalities like mitral valve prolapse (MVP) can cause ventricular arrhythmias linked to PVCs. However, MVP is often considered a structural abnormality, so it may not fit as a non-structural cause in a strict sense.

Diagnosis and Treatment

To diagnose PVCs, doctors use an electrocardiogram (ECG) or a Holter monitor, which records the heart's electrical activity for extended periods.

For many people, PVCs may not have any known cause and may go away without treatment. For others, treatment and avoiding triggers can resolve or reduce PVC occurrence.

Doctors may use antiarrhythmics (such as amiodarone and flecainide), beta-blockers, and calcium channel blockers to treat PVCs. If symptoms or frequent PVCs are present, treatment will depend on the underlying cause, which may include correcting an electrolyte imbalance or treating drug toxicity.

In cases of structural heart disease, treatments like radiofrequency catheter ablation may be used to restore a normal heart rhythm by destroying the section of heart tissue causing the PVC. Successful treatment with radiofrequency catheter ablation may reverse heart muscle damage due to PVC.

For those without structural heart disease and who are otherwise healthy, the outlook for people with PVCs is generally similar to those without PVCs. However, the mortality risk of PVCs may increase if heart disease or left ventricular dysfunction is present.

Managing PVCs

Managing stress and reducing intake of stimulants or triggers, including caffeine, can be important for treating PVCs. Regular exercise, a balanced diet, and adequate sleep can also help reduce the occurrence of PVCs.

In conclusion, while PVCs can be concerning, they are often benign and do not require treatment. For those with frequent PVCs or heart disease, treatment may be necessary. By understanding the common causes of PVCs, individuals can take steps to manage their symptoms and reduce their occurrence.
